Abstract
The invention discloses a powder coating composition with an effect of repelling insects and a preparation method of the powder coating composition. The powder coating composition is characterized by being prepared from the following components in percentage by weight: 20-30% of epoxy resin, 30-40% of polyester resin, 1-1.5% of a flatting agent, 0.3-0.5% of benzoin, 0.3-1% of polytetrafluoroethylene wax, 10-25% of titanium dioxide, 10-20% of barium sulfate and 0.1-1% of fluorine-containing pyrethroid. By selecting a safe, environment-friendly and long-acting insect repellant which is good in compatibility with raw materials in the powder coating formula, suitable for the powder coating production process and spraying process and free from side effects to product performance in production and use, the effect of repelling insects by the powder coating is realized by scientifically proportioning and adding a certain proportion of the repellant, and the coating can maintain a good coating performance and appearance.
Description
Technical field
The present invention relates to a kind of powder coating, particularly a kind of powder coating of walking quickly and keeping away insect effect.The invention further relates to the preparation method of above-mentioned powder coating.
Background technology
Powder coating is a kind of important industrial coating, current powder coating is because of its environmental protection and energy saving, VOC free discharge, the features such as one-pass film-forming is pollution-free, free from extraneous odour, and film performance excellence is attractive in appearance have become the first-selected application mode of people's daily necessitiess such as household electrical appliance, light fixture, kitchen tackle, outdoor furniture.
And in people's daily life, be often subject to the invasions of the insects such as mosquitos and flies, cockroach, ant; in the gap of refrigerator and wall, often having cockroach occurs; the frequent search of food chip of ant in kitchen; insect can invade the inside of means of illumination, and requires great effort in cleaning globe glass lamp shade inside very much.
Therefore the powder coating that makes to be coated on these products has the effect of walking quickly and keeping away insect and people is lived significant.But because production technique and the spraying curing process of powder coating all need to complete under comparatively high temps, do not have in the market after high bake solidifies, still to possess and to walk quickly and keep away insect effect, and still can keep the coating products of its good coating property.
Summary of the invention
The present invention completes in order to solve above-mentioned deficiency of the prior art, the object of this invention is to provide a kind of powder paint compositions of walking quickly and keeping away insect effect that has, another object of the present invention is to provide a kind of preparation method with the powder paint compositions of walking quickly and keeping away insect effect, the present invention is good by selecting with powder coating formula Central Plains material compatibility, can be applicable to powder coating production technique and spraying coating process, in production and use, product performance are had no side effect, safety, environmental protection, long-acting wormer, the science being listed as by the ratio of filling a prescription certain is added, reach powder coating and walk quickly and keep away the effect of insect. and make coating can keep good coating property and outward appearance.
An object of the present invention is to provide a kind of powder paint compositions of walking quickly and keeping away worm effect that has, its concrete technical scheme is as described below:
There is a powder paint compositions of walking quickly and keeping away insect effect, it is characterized in that described composition comprises following component:
Further technical scheme, described in there is the powder paint compositions of walking quickly and keeping away insect effect, it is characterized in that described composition comprises following component:
Technical scheme further, described in there is the powder paint compositions of walking quickly and keeping away insect effect, it is characterized in that described composition comprises following component:
Further technical scheme of the present invention, wherein said have a powder paint compositions of walking quickly and keeping away insect effect, it is characterized in that described fluorine-containing pyrethroid is fluorine silicon pyrethroid or fluorine the third pyrethroid.
The present invention also provides a kind of preparation method with the powder paint compositions of walking quickly and keeping away insect effect, wherein according to above-mentioned each component concentration, take each component, then by vibrin, epoxy resin, flow agent, four kinds of components of titanium dioxide are put in mixing tank and are fully stirred, churning time is 300s, after stirring, add st-yrax, tetrafluoroethylene wax, barium sulfate, fluorine-containing pyrethroid continues to stir 300s, then the raw material mixing is put in forcing machine and extruded, extruder temperature is set to first and extrudes 90 ℃, district, two extrude 95 ℃, district, by sheeter roller, be pressed into again the sheet stock of 1-10mm thickness, then by grinding machine, sheet stock is ground into powder.
The present invention adds the pyrethroid of fluoropolymer as wormer in formula, realizes the avoidance effect to insect.Pyrethroid is the broad spectrum pesticide that a class can be prevented and treated various pests, and its insecticidal toxicity improves 10～100 times than older generation sterilant as organochlorine, organophosphorus, amino formate.Pyrethroid has strong action of contace poison or fumigation action to insect, and its mechanism of action is to upset the normal physiological of insect nerve, makes it by excited, spasm death to benumbing.Pyrethroid is because consumption is little, working concentration is low, thus safer to people and animals, very little to the pollution of environment.Conventional pyrethroid temperature tolerance on market is generally 80 ℃, and powder coating temperature when producing reaches 120 ℃, when curing, temperature reaches 180 ℃ especially, we are by carrying out heatproof test and various technical screening in laboratory, discovery is in pyrethroid molecular chain after grafting fluorochemicals, the temperature tolerance of pyrethroid can arrive 200 ℃, and with powder coating in other starting material have very much good consistency, do not need existing machinery equipment in process of production, production technique is transformed.
By to the screening of fluorinated pyrethrin pesticide in the market, applicant's preferred four kinds of fluorine-containing pyrethroids in numerous sterilants carry out contrast experiment, it is extremely low that it has acute toxicity and chronic toxicity, without the feature of teratogenesis, carinogenicity risk, and has and anergy good with coating consistency.
