Embodiment 1

[0014] A filler is composed of the following raw materials in weight percentage: 35% of glass microspheres, 60% of epoxy resin curing agent, and 5% of pigments. The specifications of the glass microspheres are 100-260 mesh. The weight ratio of epoxy resin and curing agent in the epoxy resin curing agent is 1:1.

Embodiment 2

[0016] A filler is composed of the following raw materials in weight percentage: 79.5% of glass microspheres, 20% of epoxy resin curing agent, and 0.5% of pigment. The specifications of the glass microspheres are 120-200 mesh. The weight ratio of epoxy resin and curing agent in the epoxy resin curing agent is 2:1.

Embodiment 3

[0018] A filler is composed of the following raw materials in weight percentage: 57% of glass microspheres, 40% of epoxy resin curing agent, and 3% of pigments. The specifications of the glass microspheres are 140-220 mesh. The weight ratio of epoxy resin and curing agent in the epoxy resin curing agent is 3:2.

Abstract

The invention relates to a filler which is composed of the following raw materials in percentage by weight: 35-79.5% of filler, 20-60% of epoxy resin curing agent and 0.5-5% of pigment. The filler has the advantages of reasonable raw material design, convenient preparation, high impact strength, small contractibility, good sound insulation effect, high rigidity, high hardness, comprehensive comprehensive performance and wide application environment.

Description

technical field [0001] The present invention relates to a 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. 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 environment.
