Abstract

The invention relates to pre-coating adhesive used for heat cure bonding and a preparation method thereof, belonging to adhesive and a preparation method thereof and solving the problems of poor heat resisting property and poor ablation resistance of the prior adhesive and the problems of poor bonding stability and low reliability of the prior adhesive. The pre-coating adhesive is made from matrix resin, filmerformer, coupling agent, filling agent and solvent. The preparation method comprises the following steps: firstly, weighting raw materials; secondly, respectively stirring and dissolving the raw materials in a dissolution reactor; thirdly, putting the raw materials in a mixing reactor for mixing uniformly; fourthly, dispersing the mixed raw materials by a high-speed shear dispersion machine and grinding the mixed raw materials by a colloid. The pre-coating adhesive has better heat resisting property and excellent ablation resistance, not only can be used as single-coating adhesive adhering with metal or composite material and rubber in a hot cure way, but also can be used as double-coating adhesive adhering with the metal or composite material and rubber in a hot cure way, has high adhering strength and stable and reliable adhering property, and can be applied to munitions industry, constructional engineering, and the like.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof. Background technique [0002] With the development of technology and the emergence of new machines and equipment, parts that have both the mechanical properties of metal and the inherent shockproof, wear-resistant, rust-proof and other properties of rubber are required. Metal-rubber vulcanization bonding systems have been widely used in many In industrial fields, such as mechanical engineering, construction, shipbuilding and military industry, the application of metal adhesives used in metal-rubber vulcanization bonding is becoming more and more extensive, and with the rapid development of advanced resin matrix composite materials technology With the development, there are more and more occasions that require the bonding of rubber and composite materials. At present, adhesives for bonding metal and rubber are generally used to realize the bonding of rubber and composite materials. ...
