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

[0024] During preparation: add the polyether polyol to the reaction kettle at room temperature, raise the temperature to 80°C-100°C and stir, vacuumize (-0.09MPa) for dehydration and degassing for 2-3 hours, cool down to 40°C, add pure MDI, liquefy MDI, Add UV-9, BHT, phosphoric acid, react at 80-85°C for 2-3 hours, cool down to 40°C, bismorpholine diethyl ether, and put into barrels.

[0025] During construction, the binder and the rubber particles are mixed uniformly in a weight ratio of 20:100, then paved and cured (dried).

Embodiment 3

[0027] DL-3000: 40; DL-2000: 30; pure MDI: 27; UV-9: 1; BHT: 1, bismorpholine diethyl ether: 1, benzoyl chloride: 20PPM by total mass

[0028] During preparation: add the polyether polyol to the reaction kettle at room temperature, raise the temperature to 80°C-100°C and stir, vacuumize (-0.09MPa) for dehydration and degassing for 2-3 hours, cool down to 40°C and add diphenylmethane diisocyanate , add UV-9, BHT, benzoyl chloride, react at 80-85 ° C for 2-3 hours, cool down to 40 ° C, bismorpholine diethyl ether, and put into barrels.

[0029] During construction, the binder and the rubber particles are mixed uniformly in a weight ratio of 18:100, then paved and cured (dried).

[0030] The performance of the example is compared with the national standard as follows:

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 invention relates to an environment-friendly one-component polyurethane adhesive suitable for laying indoor sports venues and a preparation method thereof, more specifically 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, anti-skid, and is not affected by climatic conditions. It is very popular among 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 have become increasingly strong. sports track with a polyurethane system" proposal. However, the existing plastic runway products in China are basically TDI type. Due to the high vapor pr...
