Abstract

The invention provides a thermosetting waterproof adhesive which is applicable to a silk-screen printing mode of a traditional type, and has very strong adhesive strength after being hardened forcibly. The thermosetting waterproof adhesive is a pressure sensing adhesive of bi-component, and is applicable to the silk-screen printing. The thermosetting waterproof adhesive comprises the following raw materials, by weight, 30% to 60% of pure ethers solvent, 1% to 20% of esters solvent, 30% to 50% of acrylic ester raw materials, 1% to 10% of methacrylic acid raw materials, 0.1% to 1% of initiator, 0.5% to 1% of auxiliary additives and 0.1% to 2% of curing agents.

Description

technical field [0001] The invention relates to a thermosetting waterproof glue and a preparation method thereof. Background technique [0002] Thermosetting waterproof glue is based on the powder particles of insulator materials that are evenly distributed on the printing surface. Through the matching of different proportions of carriers, it can meet the waterproof requirements of products. It is widely used in electronic products and plastic products. [0003] The Chinese invention patent No. 200910040236.7 discloses a white adhesive for flexible printed circuits and its preparation method. The raw material components of the white adhesive include thermosetting resin, filler, thermoplastic resin, rubber, curing agent and curing accelerator. The weight ratio of raw material components is: 20-80 parts of thermosetting resin; 45-150 parts of filler; 0-60 parts of thermoplastic resin; 0-40 parts of rubber; 2-9 parts of curing agent; 0.5-2 parts of curing accelerator ; 40-120 ...
