AI Technical Summary

Problems solved by technology

Generally, it is only corroded by concentrated alkali, hydrofluoric acid and concentrated phosphoric acid. Its main components are silicon dioxide, aluminum oxide, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., and are often used as toughening agents for organic raw materials. The compatibility with organic raw materials is poor, which will reduce the storage stability of the finished product while improving the mechanical properties of the finished material

Abstract

The invention discloses a light-weight organic glass fiber composite material. The composite material is prepared from the following raw materials in parts by weight: 1-2 parts of palm wax, 0.7-1 partof epoxy chloropropane, 30-40 parts of glass fiber, 7-9 parts of abietyl alcohol, 0.5-1 part of polybenzimidazole, 1-2 parts of ammonium molybdate, 2-3 parts of hexamethylphosphoramide, 2-4 parts ofcaprylic / capric triglyceride, 2-3 parts of melamine, 0.7-1 part of p-toluene sulfonic acid, 7-10 parts of light-weight calcium carbonate, 2-3 parts of calcium ricinoleate and 50-60 parts of polycarbonate. According to the light-weight organic glass fiber composite material, the calcium carbonate and the glass fiber are respectively subjected to cyanamide and epoxidation treatment, the surfaces ofthe calcium carbonate and glass fiber are subjected to complete organification, then the calcium carbonate and the glass fiber are blended to be dispersed into the polycarbonate, the compatibility ofthe calcium carbonate and the glass fiber in the organic polycarbonate is effectively improved, so that the stability of products is improved.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a light organic glass fiber composite material and a preparation method thereof. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair. 1 / 20-1 / 5 of that, each bundle of fiber precursors consists of hundreds or even thousands of monofilaments. Glass fibers are usually used as reinforcing materials in composite materials, electrical insulation materials and thermal insulation materials, circui...
