Problems solved by technology

In CN 103215751A "a long-term insect-repellent and mosquito-repellent PP non-woven fabric", the use of permethrin to volatilize a special smell has the effect of avoiding mosquitoes, and at the same time, through the process of spunbond-meltblown-spunbond, long-term effect is achieved. Insect-proof effect, but the process temperature in this invention is very high, the decomposition temperature of permethrin is 200-220 ℃, ignoring the problem of pyrolysis and high temperature volatilization of permethrin in the process of processing

Abstract

The invention discloses a high-temperature-resistant, low-volatilization, insect-proof, halogen-free and flame-retardant PP material and a preparation method thereof. The material is composed of 60-80% of polypropylene resin, 20-30% of a halogen-free flame retardant and 5-15% of a high-temperature-resistant low-volatilization insect-proof master batch, wherein the insect-resistant master batch iscomposed of 89% of homo-polypropylene resin, 10% of insect-proof modified magnesium-aluminum hydrotalcite, 0.5% of an antioxidant and 0.5% of a lubricant. High-temperature-resistant magnesium-aluminumhydrotalcite with a layered structure is introduced and subjected to modification treatment, 2-methyl butanol, isobornyl acetate and D-borneol are introduced, and small molecular substances with certain pungent smell can be volatilized to stimulate mosquitoes, so that emergency reaction is generated, and the effect of repelling the mosquitoes is achieved; the magnesium-aluminum hydrotalcite is equivalent to a temperature-resistant protective layer, and small molecular substances in the magnesium-aluminum hydrotalcite cannot be decomposed due to hot working, so that the problem of high-temperature decomposition of easily volatile substances is effectively solved.

Description

technical field [0001] The invention belongs to the field of functional polymer materials, and relates to a high-temperature-resistant, low-volatility, insect-proof, halogen-free, flame-retardant PP material and a preparation method thereof; in particular, it relates to a PP material that limits the volatilization of volatile small molecular substances, has good insect-proof effects, and has a flame-retardant effect. A high-temperature-resistant, low-volatility, pest-proof, halogen-free flame-retardant PP material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is one of the general-purpose plastics in the world. It has many excellent properties, such as good molding performance, good chemical properties and low price, making it widely used in automobiles, home appliances, packaging , medical and other industries. However, since the limiting oxygen index of polypropylene material is only 17.5%, it is a flammable material, which limits the ...
