The application of wax emulsions is very wide, in the field of coatings, inks, textile industry, water-based adhesives are playing a significant role Wax emulsion in the field of water-based sealant, its main role is as follows. 1, Spill can be wiped to improve. 2, Improve the high and low temperature resistance and water resistance of the adhesive layer, and prevent the opening of the adhesive caused by changes in ambient temperature and humidity. Recommended reading: water-based wax emulsion for concrete mold release 3, Because of the similar structure of OPE, MAPP and PE, PP film and other non-polar polymers, the adhesion of sealant to plastic film, water-based varnish, etc. is increased, and it provides good affinity to plastic film. Precautions in the use of water-based wax emulsion 1, Water-based tackifying resin requires acid value between 20-30, acid value is too large to make the system appear gel phenomenon. The low acid value tackifying resin can also be used to dissolve with toluene and other solvents and then emulsify to join, the tackifying resin requires softening point between 70℃-90℃. 2, Keim wax emulsions are stable under alkaline conditions, such as the use of acidic acrylic emulsion, the system should be adjusted to weak alkaline with ammonia before adding PE emulsion. Otherwise, it will gel, appear particles and other phenomena. 3, Such as the use of alkali thickening thickener, it is recommended to use water to thicken the thickener to thin, in a stirred state to join, otherwise there will be particles. 4, With VAE emulsion, rosin emulsion and tackifying resin system with good stability, especially suitable for packaging lamination (BOPP film PE film, etc.) and water-based varnish after the paper edge sealing adhesive. Recommended addition amount 10%-50%.
