example 1

[0025] First, take 2kg of pigskin and wash it with water, then cut 3 incisions with a depth of 2mm on the inside of the pigskin, apply 100g of salt and 50g of white sugar evenly on the inside of the pigskin, let it stand for 40 minutes, and hang the pigskin in In the oven, dry the water at 70°C, then take out the dried pigskin, use a nail plate to evenly pierce small holes on the outside of the pigskin so that the liquid lard can flow out, and then take out the pigskin with the holes Hang it back to the oven, heat up to 150°C, continue to bake for 10 minutes and collect the dripping lard, then weigh 50g of montmorillonite and put it in a ball mill for 30 minutes, then pass it through a 200-mesh sieve, collect and sieve the montmorillonite powder, press The mass ratio is 1:10:50:100. Mix montmorillonite powder, collected lard, peach gum and water and put it into a fermenter. Stir evenly to obtain a fermentation substrate, and then add the fermentation substrate to the fermenter....

Abstract

The invention discloses a preparation method of a reinforced rubber sheet bonding layer material and belongs to the technical field of bonding material preparation. The preparation method is characterized in that the polarity of a rubber sheet is reduced by introducing nonpolar peach gum by virtue of strong polarity of butadiene-acrylonitrile rubber in the reinforced rubber sheet bonding layer material, formation of the rubber sheet is facilitated, the butadiene-acrylonitrile rubber also can serve as a toughening agent and forms one toughened granular dispersion phase in a continuous phase of terpene resin, so that the terpene resin is in a multiphase structure, and toughening effect is realized; then the surface of peach gum is modified by lard oil under the action of microorganisms, quantity of oleophilic ester groups is increased, and a chemical bonding force between the surface of the peach gum and an oil surface steel plate base is improved, so that the bonding force is enhanced; and the terpene resin has excellent bonding performance and mechanical properties, so that adhesion of a reinforced rubber sheet is further improved, the problem of fall off can not be produced during application, and the reinforced rubber sheet bonding layer material has a broad application prospect.

Description

technical field [0001] The invention discloses a method for preparing a reinforcing film adhesive layer material, which belongs to the technical field of adhesive material preparation. Background technique [0002] In order to solve the disadvantages caused by the use of thin steel plates in the automotive industry, one of the measures currently taken by the automotive industry is to apply reinforcing films on thin steel plates. [0003] Reinforcing film is a multi-layer composite material. Its main structure is that the uppermost layer is glass fiber or metal sheet skeleton material, the middle is an adhesive layer based on epoxy resin / rubber, and the bottom layer is anti-sticking paper. This composite material can be made into various geometric sizes and shapes as required. Remove the anti-adhesive paper when using it, and attach it to the surface of the steel plate to be reinforced. After the electrophoresis baking process, the adhesive layer is cured and hardened, and t...
