Embodiment 1

[0029] A. Preparation of component A (polyurethane prepolymer):

[0030] Vacuum dehydrate the polyether polyol mixture at 100°C for 2 hours, then cool to 50°C, calculate the ratio of polyether polyol and MDI required for component A with an NCO content of 9%, and then slowly add the measured MDI, the reaction temperature is controlled at 80-100°C, and the pressure is controlled at 4-6kg / cm 2 , the reaction time is 2-4 hours, until the hydroxyl groups in the system react completely;

[0031] B. Preparation of component B:

[0032] First mix 600g of mixed polyether polyol, 1100g of hydrochlorinated palm oil, and 150g of modified organic nano-montmorillonite, and use a planetary mixer or a high-shear homogeneous emulsifier to stir at high speed for 2 hours; then mix the mixed The colloid is added to the reactor, and the remaining 600g DINCH, 150g iron oxide red pigment, 50g DMTDA, 50g liquid HER, 250g titanium dioxide, 100g fumed silica, 1940g ultrafine talcum powder, 5g anti-u...

Embodiment 2

[0037] Example 2 700g mixed polyether, 1000g hydrochlorinated palm oil, 700g BENZOFLEX9-88, 100g modified organic nano-soil, 155g iron oxide red pigment, 60g DMTDA, 25g liquid HER, 150g fumed silica, 2100g superfine Talc powder, 5g anti-ultraviolet agent, and 5g antioxidant are formulated into 5kgB component according to the method described in Example 1 and synthesized track rubber sample block.

Abstract

The invention relates to an adhesive for polyurethane synthetic tracks and application thereof. The adhesive comprises an A component group and a B component group. The weight ratio of the A component group to the B component group is 1:3-8. The A component group comprises a mixture of a plurality of polyether polyols and modified liquid MDI in a weight ratio of 50-80:20-50. The B component group includes 10-40 parts of polyether polyols, 1-10 parts of an environmentally friendly chain extender, 10-40 parts of an environmentally friendly odorless plasticizer, 1-10 parts of pigment, 1-10 parts of fumed silica, 10-50 parts of an ultrafine filler, 1-10 parts of nanometer organic montmorillonite, 0.1-0.5 part of an antioxidant, and 0.1-0.5 part of an ultraviolet-resistant agent. A nanometer PU synthetic track pavement material prepared from the adhesive has more excellent weatherability, wear resistance and cohesiveness and is nontoxic, odorless and harmless to human bodies and the environment.

Description

technical field [0001] The invention relates to a polyurethane plastic track adhesive and an application thereof. The nano PU plastic track pavement material prepared by the adhesive is harmless to human body and basically has no irritating smell. Background technique [0002] PU was first used in the paving of sports grounds by the American 3M Company in the early 1960s. After years of development, PU has been used in track and field tracks, football fields, tennis courts, and children's playgrounds so far. Gym ground. Compared with the traditional soil runway, it has the characteristics of good elasticity, skid resistance, wear resistance, shock absorption, clean and flat site, easy maintenance and management, and good shock absorption. [0003] For decades, a series of PU runways have been developed successively at home and abroad. From the original TDI type, it has been improved to the MDI type, which is widely used and relatively less harmful to the human body; it is ...
