Problems solved by technology

However, the existing domestic plastic runway products are basically TDI type. Due to the high vapor pressure of TDI (1.33Pa, 20°C), there is a strong pungent smell, which is easy to damage the human respiratory system during construction and use. deals damage, and MDI has a low vapor pressure (1.5×10 -4 Pa, 20°C), basically odorless and less harmful to the human body, so it is recommended by IST

Abstract

The invention discloses an environment-friendly type monocomponent polyurethane adhesive to pave gas permeable playground, which comprises the following parts: isocyanate, polyether polyol, age resister, ultraviolet absorbent, dimorpholine ether catalyst and polymerization inhibitor, wherein the polyether polyol is polypropene oxide polyol, which is selected from one or more components of DL-2000, DL-3000, MN-3050 or 330N; the isocyanate is diphenyl methane diisocyanate; the adhesive and rubber particle are blended evenly with weight rate at 15-20: 100 to be paved and solidified (dried). The invention is superior to international index of runway, which is especially for paving indoor playground.

Description

technical field [0001] The present invention relates to an environment-friendly one-component polyurethane adhesive suitable for laying indoor sports grounds and its preparation method, more precisely an environment-friendly one-component polyurethane that does not contain TDI (toluene diisocyanate) and toxic catalysts adhesive. Background technique [0002] Polyurethane rubber sports field (referred to as plastic sports field) has the characteristics of good elasticity, wear resistance, non-slip, and not affected by weather conditions. It is popular with the public and is also the development direction of modern sports field construction. [0003] With the enhancement of people's awareness of environmental protection, the environmental protection requirements for sports venues are also increasingly strong. As early as 1994, IST (International Sports Track Technology Association) proposed "do not accept monomeric TDI components" for the problem of "using polyurethane resin t...
