Problems solved by technology

These two glues have good adhesion to metal floors and wooden floors, but have no adhesion to PVC floors, PP floors and other (composite) material floors, and cannot meet the technical requirements of lightweight development of automobiles.
In addition, neoprene solvent and water-based acrylic white latex have high TVOC value and are not environmentally friendly

Abstract

The invention relates to an environment-friendly silane-modified adhesive and its preparation method and application. The environment-friendly silane-modified adhesive is mainly composed of a specific ratio of silane-modified polymer, plasticizer, calcium oxide, filler, It is prepared from nonionic surfactant, coupling agent and catalyst. The environment-friendly silane-modified adhesive has the characteristics of fast deep-layer curing speed, good water resistance and low TVOC value, and can meet the bonding requirements of PVC floor, PP floor and other (composite) material floors in the installation process as a whole. skills requirement.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environment-friendly silane-modified adhesive, a preparation method and application thereof. Background technique [0002] Lightweight has gradually become the mainstream trend of automobile development. Because wooden floor, PVC floor, PP floor and other (composite) material floors can effectively reduce the weight of the car body, and have good sound insulation, comfort, thermal insulation and other properties, they gradually replace metal floors and become the mainstream of car decoration. Faced with the increasingly abundant floor materials, how to achieve firm bonding of these materials has become a major problem in the development of lightweight automobiles. [0003] At present, neoprene solvent glue or water-based acrylic white latex is mainly used for bonding automobile floors and floor leather. These two glues have good adhesion to metal floors and wooden floors, ...
