一种路用秸秆复合纤维材料的制备方法 A road preparing straw composite fiber materials

技术领域 Technical Field

[0001] 本发明涉及一种路用秸秆复合纤维材料的制备方法,尤其是对秸秆纤维分类资源化的提取方法。 [0001] The present invention relates to a method for preparing a road straw composite fiber material, especially straw fiber extraction method of classification of resources.

背景技术 Background

[0002] 随着国民经济的持续快速发展,现代公路交通向高速、重载、大交通量和交通渠化的方面发展,这对高速公路普遍采用的浙青混凝土路面的使用性能提出了更高的要求,从结构、材料、工艺入手解决路面早期损坏问题,形成我国重交通浙青路面的修筑技术,保证路面在使用寿命内的使用功能,降低公路的全寿命成本,路面的使用寿命力争达10-20年。 [0002] With the rapid development of national economy, modern highway traffic to high-speed, heavy-duty, high traffic volume and traffic channelization of the development, which is the use of green concrete pavement performance Zhejiang Expressway widely used higher requirements, from the structure, materials, technology start solving problems pavement early damage, the formation of heavy traffic Zhejiang green road construction technology to ensure the road surface over the life of the use of functions, reducing the whole life cost of the road, the road of life and strive to reach 10--20 years.

[0003] 路面结构体破坏是路面结构在环境(应力-温度-水力)共同作用下力学行为的直接反映,如何增加浙青混凝土路面抵抗重载作用的能力,提高疲劳寿命,延长路面使用年限,提高浙青混合料的性能是目前重载交通条件下浙青路面材料选择、结构设计所面临的重要课题。 [0003] The pavement structure damage is a direct reflection of the pavement structure under the environment (stress - hydro - temperature) joint action mechanical behavior, how to increase the capacity of Zhejiang green concrete pavement resist heavy load, improve fatigue life, extend the pavement service life, Zhejiang green mix to improve performance is an important issue Zhejiang green pavement material selection, structural design under heavy traffic conditions currently facing. 在改善浙青混合料的路用性能上主要开展的研究有三个方面:一方面是改善矿质混合料的级配来提高浙青混合料的高温抗变形能力,如浙青码蹄脂碎石(SMA)结构,多碎石(SMA)结构,大粒径浙青混凝土(LSMA)等;另一方面是改善浙青性能品质来提高浙青混合料的粘聚力,增强抵抗永久变形能力并减少感温性,如SBS 改性浙青,SBR改性浙青,PE改性浙青等;第三个重要的研究方向是在浙青混合料中加入纤维加筋材料以改善其整体的物理力学性能。 Zhejiang green mix to improve road performance with research carried out by three main aspects: one is to improve the grading of mineral mixture to increase the temperature of the mixture Zhejiang Green deformation resistance, such as Zhejiang green code Mastic Macadam ( SMA) structure, more gravel (SMA) structure, large diameter Zhejiang Green concrete (LSMA) and so on; the other is to improve the quality and to improve the performance of Zhejiang Green Zhejiang Green mix cohesion, enhance resistance to permanent deformation and reduce temperature sensitivity, such as SBS modified Zhejiang Green, SBR modified Zhejiang Green, PE modified Zhejiang green; the third important research direction is to add fiber reinforcements in Zhejiang green mix to improve their overall physical and mechanical performance. 在浙青混合料中掺入纤维成为一种提高浙青混合料性能的新手段,受到广泛的关注和重视。 In Zhejiang Green mix to improve the incorporation of fiber into a mixture of Zhejiang green performance of new means of widespread concern and attention. 在纤维拌入浙青混合料后,施工时无需大型机械设备及复杂施工工艺,从而能应用于道路工程的不同方面,如加固、修补和封闭裂缝。 After the fiber mix in Zhejiang green mix, no large-scale construction machinery and equipment and construction technology complex, which can be applied to different aspects of road projects, such as reinforcement, patching and sealing cracks. 而且对于不同环境下的路面结构,发挥其不同的有效作用,也不会明显增加路面的施工难度,这些优点都是其它加固方法所无法比拟的。 And the pavement structure under different circumstances, different play its effective role, it will not significantly increase the difficulty of the road construction, these advantages are unmatched by other methods of reinforcement.

[0004] 目前在浙青路面中掺加的纤维主要有木质素纤维、矿物纤维和有机合成纤维, 其中木质素纤维的使用最为普遍,其次为有机合成纤维和矿物纤维。 [0004] In Zhejiang Green Pavement currently incorporated fibers mainly lignin fibers, mineral fibers and organic fibers, lignin fibers in which the most common, followed by organic synthetic fibers and mineral fibers. 关于木质素纤维, 由于考虑成本及技术加工原因,国内厂家全部选用废纸作为原料,国外也有很多厂家采用废纸作原料,其中存在的主要问题:原料质量不稳定。 About lignin fibers, considering the cost and technical processing reasons, the domestic manufacturers all use of waste paper as a raw material, there are many foreign manufacturers use waste paper as raw material, main problems: the unstable quality of raw materials. 因为废纸的区别很大,有期刊,杂志,报纸,复印纸等等,其中有些纸张已经回收使用过。 Because of the large difference between the paper, there are journals, magazines, newspapers, copy paper, etc., some of which have been recovered paper used. 在选样送检时,厂家可以选送由较优质废纸加工而成的纤维产品,完全可以满足规范要求。 When sampling inspection, manufacturers can select in the processing of a relatively high-quality paper made of fiber products, fully meet the specifications. 但在实际生产中使用时,由于原料的不稳定性,导致产品质量不稳定。 However, when used in actual production, due to the instability of raw materials, resulting in unstable product quality. 且废纸油墨难以脱尽,直接影响纤维的吸油率。 And waste ink difficult Tuojin directly affect oil absorption fibers. 尽管国外有关厂家开始以木材作为原材料进行木质纤维的生产,来提高木质纤维的质量,但其价格贵,造成浪费资源。 Although the relevant foreign manufacturers began to wood as raw materials and the production of wood fiber to improve the quality of wood fiber, but its price is expensive, resulting in a waste of resources.

[0042] (6)用筛分选择粒径为0.01〜0.1mm之间的颗粒置于NaOH溶液中浸泡10小时以上后,使用搅拌机拌和成浆液,并且保证浆液易于流动,使用3000r/min以上的离心机搅拌浆液20〜30min,再经过脱水、提纯得到钠化膨润土。 [0042] (6) with a particle size of particles sieved to select between 0.01~0.1mm placed after the NaOH solution soak over 10 hours, using a stirrer mixing into a slurry, and ensure that the slurry flows easily using 3000r / min or more The slurry was stirred centrifuge 20~30min, then after dehydration, afforded the sodium bentonite.

[0043] (7)取钠化膨润土,加入水制成浆液。 [0043] (7) to take sodium bentonite, adding water to make a slurry. 向浆液中添加质量为钠化膨润土的20%〜30%的溴十六烷基三甲铵(简称为CTMB)对钠化膨润土进行化学反应改性。 Adding to the slurry quality sodium bentonite 20% ~ 30% of bromine cetyltrimethylammonium (referred to as CTMB) of sodium bentonite modified chemical reaction.

[0044] (8)采用柴油提纯经(7)化学改性的膨润土。 [0044] (8) through the use of diesel fuel purification (7) chemically modified bentonite. 向提纯出来的改性膨润土中加水, 并在打浆机中打制成含水率在150%〜200%的浆液,并不断搅拌,制成改性膨润土浆。 Out of the bentonite to purify water was added, and the beater hit made moisture content of 150% ~ 200% of the slurry, stirring constantly, made of modified bentonite slurry.

[0045] (9)将处理后的粗纤维制成pH为8.0的浆液并与(8)中配制的改性膨润土浆均勻拌和,取6Kg纤维浆和IKg改性膨润土浆,即把纤维、膨润土的混合浆先搅拌30〜 40min后再朝一个方向搅拌,并采用离心机筛分(混合浆在不同筛孔的过滤筛中离心分开,离心机转速控制在4000r/min,提取纤维长度在1〜1.5mm之间的吸附有改性膨润土的纤维。 [0045] (9) of the crude fiber processed into a slurry pH of 8.0 with (8) formulated bentonite slurry evenly mixing, take 6Kg fiber pulp and IKg bentonite slurry, that is, the fiber, bentonite The mixed slurry was stirred first 30~ 40min before stirring in one direction, and the use of centrifuges screening (mixed pulp in different filter mesh sieve separated by centrifugation, the centrifuge speed control at 4000r / min, extracting fiber length in 1 ~ 1.5mm between adsorption has modified bentonite fibers.

[0046] (10)将提取的长度在1〜1.5mm之间的纤维4.5Kg,加水45kg水和硅烷偶联剂22.5g制成乳浊液,拌和10分钟。 [0046] (10) the length of the fibers extracted 4.5Kg 1~1.5mm between 45kg water 22.5g water and the silane coupling agent made of emulsion, mixing for 10 minutes. 对于混合液进行脱水处理后再控制温度130°C下烘干, 便得到了复合路用纤维材料。 For the dehydrated mixture to control the temperature after drying at 130 ° C, it was a composite fiber material way.
