Problems solved by technology

[0002] The current water-based adhesive has many important advantages. It uses water as the medium, does not use organic solvents, is non-toxic or flammable, is an environmentally friendly product, has no solvent recovery, and has low cost. To bond corrugated filter materials, because the current market products are used to bond corrugated filter materials produced by our company, the adhesive is easily absorbed by corrugated filter materials, resulting in poor bonding strength, or high shear strength, corrugated filter materials Difficult to cut, or the curing time of the glue is long, causing the filter materials to stick to each other during curing, or the water resistance is not good
[0003] Since the existing adhesives are far from meeting the production needs, and the water-based adhesives are widely used
A water-based adhesive suitable for bonding corrugated filter media is hereby developed, hoping to solve the bottleneck of the production process caused by adhesives in the production of corrugated filter media at present, and to provide the possibility for the production of special functional corrugated filter media

Abstract

The invention discloses a preparation method of waterborne adhesive for a waterproof corrugated filter material. The waterborne adhesive for the waterproof corrugated filter material is prepared from,by mass, 60-80% of water, 10-20% of polyacrylate, 5-10% of polyurethane adhesive, 5-10% of silica powder, 1-5% of plasticizer and 1-5% of thickening agent. The preparation method of the waterborne adhesive for the waterproof corrugated filter material is simple; the waterborne adhesive is not easily absorbed by the corrugated filter material, an adhering effect can be achieved simply by using a small quantity of the waterborne adhesive, the bonding strength is high, the water resistance of the adhesive is improved to a certain degree, and more processing modes are provided for post-processingof the corrugated filter material; the surface of the waterborne adhesive is dry and smooth and not attached to the hands, the waterborne adhesive does not harden after being solidified, and the bodyof the waterborne adhesive is soft; when finally cut, the whole waterproof corrugated filter material can be cut, the cutting resistance is low, the waterborne adhesive is not attached to a cutter during cutting, therefore, the waterproof corrugated filter material is cut smoothly under the condition of thick stacks, and the production efficiency is improved.
