Abstract

The invention provides an environmentally friendly silane graft modified polymer (SGP) elastic layer material, which includes the following components in weight percentage: silane modified polyurethane resin: 5-15%; silane modified polyether resin: 5-15% %; Environmental diluent: 15‑45%; Filler: 30‑60%; Pigment: 0.3‑0.8%; Coupling agent: 0.4‑1.0%; Water remover: 0.4‑1.0%; Catalyst: 0.2‑1.2%; Flame retardants: 3‑8%. The environmentally friendly silane graft modified polymer (SGP) elastic layer material of the present invention quotes silane graft polyether resin, which has better weather resistance, water resistance and flexibility than polyurethane, and its physical properties are better than polyurethane materials. Better and more suitable for laying sports ground materials.

Description

technical field [0001] The invention relates to the field of silane graft modified materials, in particular to an environmentally friendly silane graft modified polymer (SGP) elastic layer material and a preparation method thereof. Background technique [0002] Nowadays, many plastic runways and stadiums use polyurethane materials as elastic layer materials. Although polyurethane has good elasticity, good wear resistance, aging resistance, low temperature resistance, and softness can be adjusted, its single component can be used in high temperature and high humidity conditions. Bubbles are easy to form under the environment, and the mechanical properties will be greatly reduced. After being made into two components, problems such as inaccurate ingredients of components, difficulty in eliminating bubbles by mechanical stirring, and inconvenient construction are often encountered. [0003] With the introduction of GB36246-2018 "Sports Fields with Synthetic Surfaces for Primary...
