Problems solved by technology

However, the method of this technology to eliminate low-VOC harmful gases is mainly physical adsorption, and physical adsorption is saturated. Zinc ricinoleic acid can only decompose part of harmful gases, and has no effect on formaldehyde and other aldehydes and benzene. The antibacterial agent used It only has a certain bactericidal effect and does not eliminate the effect of low-VOC harmful gases. Therefore, the bactericidal effect of this technology is very limited, and due to the poor compatibility between the hydrophobic high-temperature-resistant odor adsorption masterbatch and the base material, it affects the mechanical properties of the material obtained by this technology. performance

Abstract

The invention discloses a low-odor sterilization micro-bubbling scratching-resistant nylon composite material and a preparation method thereof. The composite material is prepared from nylon 6, a compatilizer, a micro-sphere foaming agent, a starching-resistant resin, a low-volatile substance adsorbent, a wrapping treatment lytic enzyme, a nano photocatalyst, a lubricant, an antioxidant and a thermal stabilizer in parts by weight. As the low-volatile substance adsorbent in the material is particularly good in adsorption property, low-volatile substance harmful gases generated from parts made ofthe material can be effectively prevented; due to adoption of the wrapping treatment lytic enzyme and the nano photocatalyst, trace low-volatile harmful gasses generated from parts made of the material and low-volatile harmful gasses generated from ambient environments of the parts can be decomposed into harmless carbon dioxide and water. After microsphere treatment, nylon 6 has relatively low density and water absorption, relatively high elasticity, relatively excellent anti-shock pressure-resistant buffer thermal-insulating noise reduction and a relatively beautiful surface effect, and automatable lightening and humanized development tendency are met.

Description

technical field [0001] The invention relates to the technical field of modification of nylon materials, in particular to a micro-foaming scratch-resistant nylon composite material with low odor and bactericidal function and a preparation method thereof. Background technique [0002] Polyamide-6, also known as polycaprolactam, has excellent wear resistance and self-lubricating properties, high heat resistance and mechanical strength, excellent low temperature performance, self-extinguishing, oil resistance, chemical resistance, good elasticity, high impact strength , shock resistance and noise absorption, excellent alkali resistance, UV and sunlight resistance, relatively small density, and easy processing, the disadvantage is large shrinkage rate and poor dimensional stability. Because of the above advantages, nylon 6 is now playing an increasingly important role in the production of auto parts. [0003] In recent years, domestic consumer rights protection incidents related...
