Abstract
The invention discloses a preparation method of a board adhesive. The board adhesive comprises the following components in parts by weight: 40-50 parts of polyvinyl alcohol, 30-55 parts of acetaldehyde, 15-20 parts of polyvinyl butyral, 30-55 parts of epoxy resin, 7-12 parts of silane coupling agent, 25-30 parts of filler and 2-5 parts of solvent. The preparation method comprises the following steps: mixing the polyvinyl alcohol, acetaldehyde, polyvinyl butyral and epoxy resin according to parts by weight, reacting at 70-90 DEG C for 1-2 hours, filtering out the intermediate product, sequentially adding the intermediate product, a silane coupling agent, a filler and a solvent into a stirrer, stirring, and reacting at 30-40 DEG C for 1-2 hours to generate the finished product. The board adhesive has the advantages of high adhesive force, moisture resistance and corrosion resistance. The added coupling agent increases the adhesive force. The added filler and solvent lower the production cost on the premise of not influencing the adhesive effects of the adhesive.
Description
Technical field
The present invention relates to the preparation method of a kind of adhesive, particularly relate to the preparation method of a kind of sheet material adhesive.
Background technology
Adhesive has higher metal and resin bonding ability and antistripping ability, can be used for the compound of aluminium foil and resin base material.But when aluminium foil is double-zero aluminum foil or single zero aluminium foil, himself surface is accompanied with a certain amount of greasy residues, restriction aluminium foil and the compound ability of other materials.Existing conventional adhesive, gumminess is poor, meets water easily separated, it is clear that can not meet use requirement.Accordingly, it would be desirable to a kind of new technical scheme solves the problems referred to above.
Summary of the invention
For solving the problems referred to above, the present invention provides the preparation method of a kind of sheet material adhesive.
The technical solution used in the present invention:
A kind of preparation method of sheet material adhesive, each composition including following weight portion: the polyvinyl alcohol of 40-50 part, the acetaldehyde of 30-55 part, the polyvinyl butyral resin of 15-20 part, the epoxy resin of 30-55 part, the silane coupler of 7-12 part, the filler of 25-30 part and the solvent of 2-5 part, according to above-mentioned weight portion, by polyvinyl alcohol, acetaldehyde, polyvinyl butyral resin and epoxy resin mixing, temperature is set to 70-90 DEG C, 1-2 hour time, filter out intermediate product, previous step is produced intermediate product and silane coupler, filler and solvent are sequentially added in blender and are stirred, temperature 30-40 DEG C, 1-2 hour response time, generate finished product.
Described filler is the one in calcium carbonate, barium sulfate and aluminium powder.
Described diluent is the one in methanol, ethanol and toluene.
Beneficial effects of the present invention: the sheet material adhesive cohesive force of the present invention is good, moisture resistance, anticorrosion, and the coupling agent of interpolation adds cohesive force, the filler of increase and solvent, is not affecting the gluing effect of adhesive, is reducing production cost.
