Novel filling agent

Abstract

The invention discloses a novel filling agent which is characterized in that the filling agent is prepared by mixing polyurethane foam, asbestos, titanium oxide, diatomite, alumina powder, boric acid and emery according to a mass ratio of 4:1:3:1:2:0.5:1. The product provided by the invention has high impact strength, low shrinkage, good sound insulation effect, relatively high rigidity, and relatively high hardness. The filling agent also has a flame-retardant function. The filling agent has comprehensive overall performance, and has wide application environments.

Description

technical field [0001] The invention is suitable for the field of materials, in particular it is a novel filler. Background technique [0002] Fillers are also known as fillers and fillers. Its function is to add solid substances to materials to improve performance or reduce costs. Fillers usually do not contain water, are neutral, and organic, inorganic, metal or non-metallic powders that do not have adverse effects on material components can be used as fillers. However, the existing fillers often have single components and have their own defects, such as low impact strength, high shrinkage, no sound insulation, and weak rigidity and hardness, so most of them cannot meet various requirements and Complicated use environment, very troublesome. [0003] Therefore, there is an urgent need for a new type of filler with high impact strength, low shrinkage, good sound insulation effect, high rigidity and hardness, comprehensive comprehensive performance, and wide application e...
