Abstract
The invention relates to a method for adopting waste polystyrene foaming material to prepare PVC artificial leather. Currently, a large quantity of waste polystyrene foaming packing materials have the disadvantages of relatively high cost for being recycled and transported to manufacturing enterprises of PVC artificial leather due to small specific gravity and large volume and serious pollution to the environment without automatic degradation of the foaming packing materials. At correspondingly concentrated recycling points, the invention adopts mixed toluene and butanone or dioctyl phthalate (DOP) for solving the waste polystyrene foaming packing materials. After being obtained, gluing solution or No. 1 artificial leather raw material is transported to the PVC manufacturing artificial leather enterprises to be first processed into artificial leather adhesive, artificial leather surface layer material and raw material for artificial leather foaming layer. Then, the PVC artificial leather is manufactured according to a traditional method. With the waste polystyrene foaming packing material which is difficultly recovered in the past used as the raw material of PVC artificial leather, not only can the production cost be lowered but also white pollution are reduced. The method is beneficial to the environmental protection.
Description
Technical field
The present invention relates to artificial leather and make the field, particularly a kind of method that adopts waste polystyrol foam material to make artificial polyvinyl chloride leather.
Background technology
The manufacture method of existing artificial polyvinyl chloride leather adopts the polyvinyl chloride virgin material mostly, and cost is higher; Also adopt polyvinyl chloride leftover bits or waste product to make auxiliary material to reduce cost.But current a large amount of employing polystyrol foam material is made the damping packing articles of various electrical equipment, instrument, take packing apart after, discarded immediately; The proportion of these goods is minimum, and is bulky, and the transportation of recovery, to deposit cost higher relatively, and the profit that reclaims these goods is very little, lacks to reclaim enthusiasm, thereby hinders the recycling of these goods.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method that waste polystyrol foam material is made artificial polyvinyl chloride leather of recycling,
For solving the problems of the technologies described above, technical scheme of the present invention comprises following process steps:
(1) 40-70 weight portion waste polystyrol foam material, 100 weight portion dioctyl phthalates are added agitator, the evenly mixed 1# artificial leather raw material that gets, standby;
(2) the 1# artificial leather raw material that 100 weight portion polyvinyl chloride, 60-70 weight portion dioctyl phthalate, 10-60 weight portion step (1) are made, 1-5 weight portion barium zinc stabilizer and 2-5 weight portion colorant add agitator, the evenly mixed artificial leather surface layer raw material that gets, standby;
(3) the 1# artificial leather raw material that 100 weight portion polyvinyl chloride, 60-70 weight portion dioctyl phthalate, 10-80 weight portion step (1) are made, 1-5 weight portion potassium zinc stabilizer, 20-100 weight portion dicalcium powder, 1-5 weight portion blowing agent, 3-8 weight portion thinner and 2-5 weight portion colorant add agitator, the evenly mixed artificial leather foaming layer raw material that gets, standby;
(4) 90 parts by weight of toluene and 10 weight portion butanone are mixed in agitator, 40-70 weight portion waste polystyrol foam material is added in the agitator dissolve again, get mixed solution;
(5) mixed solution that 100 weight portion polyvinyl chloride, 60-80 weight portion dioctyl phthalate and 10-30 weight portion step (4) is made adds agitator, and the evenly mixed artificial leather adhesive that gets is standby;
(6) the artificial leather foaming layer raw material that adopts artificial leather adhesive that step (5) makes, artificial leather surface layer raw material that step (2) makes and step (3) to make is made artificial polyvinyl chloride leather by following method;
A. first coating machine carries out the slurry coating first time to the release liners of input, the artificial leather surface layer raw material that slurry adopts step (2) to make, and the release liners that be coated with behind the artificial leather surface layer raw material first time changes second coating machine over to behind curing oven;
B. second coating machine is to carrying out the slurry coating second time from the release liners of first coating machine input, the artificial leather foaming layer raw material that slurry adopts step (3) to make, the release liners that is coated with the second time behind the artificial leather foaming layer raw material changes the 3rd coating machine over to after curing oven and foaming;
C. the 3rd coating machine is to carrying out slurry coating for the third time, the artificial leather adhesive that slurry adopts step (5) to make from the release liners of second coating machine input; Cover knitted cloth, Woven Fabrics or nonwoven fabric on the release liners after being coated with the artificial leather adhesive for the third time again, behind curing oven, change cooling and shaping over to;
D. separate release liners and promptly make the artificial polyvinyl chloride leather finished product.
The invention has the beneficial effects as follows: current a large amount of discarded foamed polystyrene packaging material are minimum because of proportion, bulky, and it is higher relatively to reclaim the cost that is transported to artificial polyvinyl chloride leather manufacturing enterprise, lack and reclaim enthusiasm; Foam package material can not be degraded voluntarily, and particularly the particle of its lightweight waves everywhere, serious environment pollution.The present invention is the recovery point of concentrating relatively, adopt the toluene and butanone or the discarded foamed polystyrene packaging material of dioctyl phthalate [DOP] dissolving that mix, after making adhesive solution or 1# artificial leather raw material, be transported to artificial polyvinyl chloride leather manufacturing enterprise again and be processed into artificial leather adhesive, artificial leather surface layer raw material and artificial leather foaming layer raw material earlier, make artificial polyvinyl chloride leather by traditional method subsequently.Utilize the waste polystyrene foam package material that in the past was difficult to reclaim to make the raw material of artificial polyvinyl chloride leather, not only can reduce production costs, and reduce white pollution, help environmental protection.
