Abstract

The present invention relates to actylic resin, and especially water base type cationic actylic resin adhesive and its preparation process. The water base type cationic actylic resin adhesive consists of water thinned cationic actylate resin in 75-90 weight portions and water thinned natural or synthetic cationic or non-ionic polymer solution. The cationic emulsifier is polynary copolymer emulsion including N, N'-dimethyl amino ethyl acrylate, butyl acrylate, styrene, 2-ethyl hexyl acrylate, etc. Compared with available technology, the present invention has the advantages of raised adhesion, raised waterproof performance, no toxicity and environment friendship, and is especially suitable for use in finishing household, office, etc.

Description

technical field [0001] The invention belongs to the technical field of light industry and chemical industry. It relates to an acrylic resin, specifically a water-based cationic acrylic resin adhesive and a preparation method thereof. Background technique [0002] Adhesives are generally divided into two categories: solvent-based and water-based. It is obvious that solvent-based adhesives have adverse effects of polluting the environment and endangering personal health. It also causes huge consumption of energy. It not only increases the cost but also irreversibly loses the limited energy in the human world. For example, urea-formaldehyde resin adhesives, phenolic resin adhesives, etc., which are commonly used at present, not only contain a certain amount of unreacted formaldehyde and cause damage to the human body, but also continuously release formaldehyde during the aging process to cause lasting damage to the human body. Another example is polyvinyl formal adhesive, c...
