Abstract

The invention discloses an inorganic particle enhanced PTT / TPEE composite material. The composite material comprises the following ingredients, by weight, 50%-85% of PTT, 5%-25% of TPEE, 2%-5% of poly(diisobutyl adipate), 5%-25% of inorganic particles, 0.5%-2% of light stabilizing agents, 0.1%-0.5% of coupling agents, 0.1%-0.5% of anti-oxidants and 0.1%-1% of lubricants. The inorganic particles are one selected from heavy calcium carbonate, fumed silica, talcum powder, calcium oxide, aluminium hydroxide and magnesium hydroxide. The beneficial effects are that the composite material has excellent mechanical properties, heat resistance and corrosion resistance, the ageing resistance is good, the preparation technology is simple, the production cost is low, and popularization is easy.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an inorganic particle reinforced PTT / TPEE composite material. Background technique [0002] Polytrimethylene terephthalate (PTT), as a new type of polyester polymer material with excellent comprehensive properties, has been widely used in the fields of fibers, films, engineering plastics, etc., but PTT alone has low strength and thermal stability. Not good, the anti-aging performance is not strong. Polyether ester (TPEE) is polybutylene terephthalate-polyethylene oxide-polypropylene oxide thermoplastic elastomer, which is composed of dimethyl terephthalate, butylene glycol, polyethylene oxide two A block copolymer obtained by polycondensation of polyalcohols and / or polypropylene oxide diols, which has the elasticity of rubber and the strength of engineering plastics, and will have better processability and longer service life than rubber , Compared with engineering ma...
