The invention discloses a high temperature-resistant, low-volatility, insect-proof, halogen-free flame-retardant PP material and a preparation method thereof; The composition of 5-15% of the particles: the formulation of the insect-proof master batch is: 89% of homopolypropylene resin, 10% of insect-proof modified magnesium-aluminum hydrotalcite, 0.5% of antioxidant, and 0.5% of lubricant. In the present invention, high temperature-resistant magnesium-aluminum hydrotalcite with a layered structure is introduced, which is further modified, and 2-methyl butanol, isobornyl acetate and dextroborneol are introduced to volatilize a certain pungent odor. Mosquitoes are stimulated by small molecular substances, so that they have an emergency response, so as to achieve the effect of repelling mosquitoes; among them, magnesium-aluminum hydrotalcite is quite a temperature-resistant protective layer, and the internal small molecular substances will not be decomposed by thermal processing, effectively It solves the problem of high temperature decomposition of volatile substances. |
