Problems solved by technology

However, adhesives that are effective for bonding polar materials are extremely poor for bonding non-polar materials, and adhesives that are suitable for bonding non-polar materials are not suitable for bonding polar materials; With the development of the automotive material industry and the diversification of materials for automotive interior parts, the bonding between polar materials and non-polar materials has become a development trend. Traditional adhesives are obviously no longer able to meet the needs of automotive interiors. Adhesives with good adhesion to both polar substrates and non-polar substrates are urgently needed
On the other hand, traditional solvent-based adhesives contain toxic substances such as benzene, which are harmful to human health and do not conform to the international mainstream of environmental protection.

Abstract

The invention discloses a moisture cured multi-constituties grafting solvent-based adhesive, which is prepared by processing the following components in part by weight: 5 to 15 parts of main body, 0 to 0.2 part of initiator, 0.2 to 10 parts of grafting monomer, 1 to 15 parts of thickening agent, 0 to 1 part of antioxidant, 0.5 to 2.5 parts of silane coupling agent and 31 to 95 parts of solvent through processes of grafting, coupling and the like. The adhesive does not contain toxic substances such as benzene and the like which are harmful to human bodies, and has the advantages of good stability of components of products, safety and environmental protection; and simultaneously, the adhesive has the excellent cohesive force for polar materials and nonpolar materials, can bond various materials such as rubber, leather, fabrics, foam plastics, PVC leather, PU leather, plastics, surface veneer of color prints and the like, and are widely suitable for vehicle material markets and shoe manufacturing industry.

Description

technical field [0001] The invention belongs to the field of adhesives, in particular to a moisture-cured multi-component grafting solvent-based adhesive.
