Abstract

The invention discloses a PVC material composite water-based adhesive. The composite water-based adhesive is prepared from the following raw materials in parts by weight: 35-50 parts of polyurethane modified acrylic prepolymer, 15-20 parts of petroleum resin, 9-12 parts of rosin resin, 4-6 parts of a plasticizer, 6.5-8.5 parts of organosiloxane monomer, 1-5 parts of an initiator and 5-8 parts of an accelerant. The PVC material composite water-based adhesive prepared by the invention has good bonding strength, good leveling property, smooth surface after coating and no agglomeration, caking orwatermarks, and does not yellow after being placed for 30 days after being used.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a PVC material composite water-based adhesive and a preparation method thereof. Background technique [0002] PVC (polyvinyl chloride) floor material is a new type of light-weight floor decoration material, which can be widely used in various places such as families, hospitals, schools, office buildings, factories, public places, supermarkets, and businesses. The water-based adhesive used for bonding PVC materials is a kind of adhesive that has a fast transparent speed during use, almost no glue traces can be seen after completion, and has a very light smell and strong viscosity after painting. [0003] At present, the PVC material composite water-based adhesives on the market often have insufficient bonding strength, or poor leveling during use, and are prone to agglomeration and agglomeration. After being placed for a period of time after use, yellowing is prone to occur, which affects...
