Attapulgite-modified pbt material and preparation method thereof

Abstract

The invention discloses an attapulgite modified PBT material, which is composed of the following raw materials in parts by weight: aluminum potassium sulfate 1-2, potassium dihydrogen phosphate 3-4, caprolactam 70-80, attapulgite 10-10 13. Zinc acetate 1‑1.4, γ‑aminopropyltriethoxysilane 2‑3, oxalic acid 18‑20, polybutylene terephthalate 300‑370, monoglyceryl monostearate 2 ‑4, 2‑mercaptobenzimidazole 1.7‑2, butyl acrylate 10‑15, ethylene bisstearamide 2‑3, polytetrahydrofuran ether glycol 4‑6, quicklime 2‑3. The material of the invention can form a "micro-network" structure with the masterbatch as the core, thereby increasing the strength and toughness of the polyamide matrix material, and facilitating the dispersion of the composite material in the polyamide matrix material.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to an attapulgite modified pbt material and a preparation method thereof. Background technique [0002] As a photocatalytic antibacterial agent, ZnO has been widely studied in recent years, and it generates strong oxidative active functional groups under photocatalysis to kill bacteria. It has the advantages of non-toxic, non-irritating, good stability, difficult to decompose at high temperature, long-term aging, low price, abundant resources, etc., and has broad application prospects; [0003] At present, the commonly used supports for supporting photocatalysts mainly include carbon nanotubes (CNTs) and activated carbon, mesoporous materials, silica and zeolite. High stability. Nano-photocatalyst / porous mineral composite system, that is, assembling or loading nano-semiconductor photocatalysts into the pores or surfaces of mineral materials, not only solves the problem of agglom...

Problems solved by technology

However, during the application process, the polar group of the polyamide 6 material makes it easy to absorb water, resulting in low dry and low temperature impact strength, poor product stability, prone to plastic deformation due to friction, and severe wear. In addition, as a mine The use of engineering plastics does not have antistatic properties and is prone to gas explosions, etc., which affects the dimensional stability, anti-wear and anti-friction properties and electrical properties of its products, which limits its application range;
