Abstract

The invention provides environment-friendly two-component polyurethane lawn glue with high initial adhesion and easy construction. The lawn glue comprises a component A and a component B in a mass ratio of 1:4. The component A is 25 parts of a curing agent; and the component B is prepared from the following components in parts by weight: 3-8 parts of polytetrahydrofuran ether glycol, 15-25 parts of 2-functional group polyether, 5-15 parts of polyfunctional group polyether, 0.2-1 part of 403 polyether, 2-6 parts of a chain extender, 5-15 parts of a plasticizer, 25-40 parts of filler, 5-15 parts of tackifying resin, 0.2-1 part of a coupling agent, 0.01-0.5 part of a catalyst, 0.2-1 part of a dewatering agent, and 0.1-2 parts of a pigment. According to the environment-friendly two-component polyurethane lawn glue with high initial adhesion and easy construction, the influence of solvent volatilization of a solvent type lawn glue on the environment is avoided, and the defects that common two-component polyurethane lawn glue is high in viscosity and difficult to construct, and misalignment and displacement phenomena caused by low initial adhesion are overcome.

Description

technical field [0001] The invention relates to the technical field of artificial turf paving glue, in particular to an environmentally friendly two-component polyurethane lawn glue with high initial adhesion and easy construction and a preparation method thereof. Background technique [0002] Lawn glue is a special adhesive specially used for artificial turf / turf paving and fixing. It is a special-purpose universal glue with special additions and excellent weather resistance and water resistance. [0003] More than 95% of the popular lawn paving adhesives on the market are solvent-based resin adhesives. The organic solvent of solvent-based resin glue volatilizes, releases in the air, or adheres to the artificial turf, causing environmental pollution and seriously endangering human health. meets the. [0004] For this reason, people have developed two-component polyurethane lawn glue, because it does not contain solvents, so the environmental protection performance has bee...
