Abstract

The invention relates to an adhesive agent specially used for a metal plate and the preparation method. The formulation is mainly made by the components according to the weight parts: 86 parts to 100 parts of amine terminated liquid nitrile rubber, 40 parts to 50 parts of bisphenol A epoxy resin, 5 parts to 7 parts of nanometer silica, 5 parts to 7 parts of nanometer alumina, 1 part to 2 parts of silane coupling agent, 2.5 parts to 4 parts of dicumyl peroxide, 1 part to 2 parts of triallyl cyanurate, 30 parts to 40 parts of methyl hexahydro phthalic anhydride, 0.5 part to 1 part of benzyl triethyl ammonium chloride and 50 parts to 60 parts of acetic ether. The adhesive agent is used for compounding two layers of the metal plates, and when compared with the traditional adhesive agent, both the shear strength and the peel strength are greatly enhanced. The compounded metal plate bonded by the adhesive agent is particularly suitable for manufacturing a damping and deadening disc, because the damping coefficient of which is high. In addition, the raw material adopted in the adhesive agent belongs to the environmental protection product, and during the large-scale industry application, the problem of the environmental pollution can not be generated.

Description

technical field [0001] The invention relates to an adhesive, in particular to a special adhesive for metal plates and a preparation method thereof. Background technique [0002] The shock-absorbing and noise-absorbing pad is an important part of the brake pad. When the brake pad is braking, the shock-absorbing and noise-absorbing pad can damp the vibration and noise caused by the friction block in the brake pad. At present, there is a shock-absorbing and sound-absorbing sheet of a composite structure, which is formed by bonding two layers of metal sheets. Compared with the ordinary shock-absorbing and sound-absorbing sheet using a single-layer metal plate, the shock-absorbing sheet with a composite structure has better strength, excellent shock-absorbing and sound-absorbing properties. In this shock absorber, the glue that bonds the two metal sheets is the key factor. Since glue and metal are two different materials, their chemical structure and mechanical properties are v...
