Embodiment 1

[0023] In parts by weight, each raw material was weighed: 160 parts of trimethylene carbonate monomer, 3 parts of pyromellitic dianhydride, 2 parts of ammonium molybdate, 8 parts of oxidized polyethylene wax, 12 parts of polyether glycol 1 part of vinyl distearic acid amide, 2 parts of calcium acetylacetonate, 13 parts of light filler, 2 parts of trimethylolpropane, 0.4 part of 2-mercaptobenzimidazole, 5 parts of N-methylpyrrolidone , 1 part of sorbitan monooleate, 0.2 part of stannous sulfide, and 20 parts of anhydrous toluene.

[0024] Wherein, the light filler is composed of light calcium carbonate and diatomaceous earth with a weight ratio of 6:1.

[0025] Each raw material that weighs is carried out preparation lightweight polycarbonate material, and specific preparation steps are:

[0026] (1) Take 2-mercaptobenzimidazole, add it to 15 times its weight in absolute ethanol, stir evenly, raise the temperature to 70°C, add trimethylolpropane, keep stirring for 10 minutes, ...

Abstract

The invention discloses a lightweight polycarbonate material, made from, by weight, 140-160 parts of a carbonate monomer, 2-3 parts of pyromellitic dianhydride, 1-2 parts of ammonium molybdate, 6-8 parts of oxidized polyethylene wax, 10-12 parts of polyether glycol, 0.8-1 part of ethylene bis-stearamide, 1-2 parts of calcium acetylacetonate, 10-13 parts of lightweight filler, 1-2 parts of trimethylolpropane, 0.4-1 part of 2-mercaptobenzimidazole, 3-5 parts of N-methylpyrrolidone, 0.8-1 part of sorbitan monooleate, 0.1-0.2 part of stannous sulfide, and 16-20 parts of anhydrous toluene. The lightweight filler is organically modified and is subjected to mixed esterification with acid-doped polyester, the dispersity of the lightweight filler in a polyester matrix is effectively improved, the compatibility of the lightweight filler with other materials is improved, the stability strength of a finished product is improved, and the mechanical properties of the finished product are enhanced.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a lightweight polycarbonate material. Background technique [0002] The three major application areas of polycarbonate engineering plastics are glass assembly industry, automobile industry and electronics and electrical industry, followed by industrial machinery parts, CDs, packaging, computers and other office equipment, medical and health care, films, leisure and protective equipment, etc. . Polycarbonate can be used as door and window glass, and polycarbonate laminates are widely used in banks, embassies, detention centers and protective windows in public places, for aircraft canopies, lighting equipment, industrial safety baffles and bulletproof glass. Polycarbonate sheets can be used for various signs, such as gasoline pump dials, car dashboards, warehouse and open-air commercial signs, dot-type sliding indicators, polycarbonate resins are used in automotive lighting sy...
