Abstract

The invention discloses a pouring sealant for an automobile igniter and a preparation method and an application thereof. The pouring sealant for an automobile igniter is prepared by solidifying material A and material B with the mass ratio of 100:(15-50), wherein the material A consists of spare resin, 42mum fusion silica powder, 25mum fusion silica powder, an anti-settling agent, an antifoaming agent, a coupling agent and color paste; and the material B consists of methyl tetralin phthalic anhydride, hexahydrophthalic anhydride, polyether, di-hexyl tetramethyl imidazole and antioxygen. Through formulation of components with a specific proportion, the epoxy resin pouring sealant for automobile igniters produced by a special process is used for insulating and waterproof protective encapsulation of automobile igniters. The pouring sealant for an automobile igniter has the advantages of environmental change resistance to high pressure and high-low temperature, strong cracking resistance and long service life.

Description

technical field [0001] The invention belongs to the field of potting glue materials, and relates to a potting glue for automobile igniters and a preparation method and application thereof. Background technique [0002] With the rapid development of China's economy, automobiles have entered thousands of households, and more than ten million automobiles are entering the market every year. As the main component of automobiles, the consumption of igniters is also increasing. Epoxy resin potting glue for igniters The consumption of epoxy resin is also increasing rapidly. Due to the high withstand voltage and extremely high temperature resistance requirements of this product, it also requires a long service life. As a key component of the car, the quality of the epoxy resin potting compound also received special attention. In the past, this product was mainly produced by major scale adhesive companies in Japan, Germany, the United States and other countries. Some domestic compani...
