Problems solved by technology

[0003] There are several main problems in this formula system: 1), due to the main mechanical properties of the product, such as the elongation at break is only 105%, it cannot adapt to the foundation fracture, bulge, and subsidence of sports venues due to ground freezing, water immersion, etc. The stress generated by such deformation causes the fracture of the polyurethane paving material; 2), the flame retardant performance of the product is low, in fact, the flame retardant performance of most domestic products has not reached the first-class flame retardant standard; 3), in order to Anti-aging, anti-mildew, adding a variety of expensive anti-ultraviolet agents, antioxidants and anti-fungal agents, which greatly increases the cost, but the amount added is far from the actual demand, and the effect is not ideal

Abstract

An environment protection type composite polyurethane elastomer / nano laminated material is prepared through vacuum heating of dihydroxy polyoxyacrylether, dewatering, adding the mixture (MDI-50) of 4,4'-and 2,4'-diphenylmethane diisocyanate, reacting to obtain component A, compounding organic laminated nano material with trihydroxy or dihydroxy polyoxyacrylether, mixing with metaphenyldiamine pigment, filler and plasticizer to obtain component B, proportionally mixing components A with B, and laminating polymerization reaction under catalysis of zinc naphthenate. Its advantages are no pollution on preparing and using it, high mechanical performance, and excellent flame-retarding and anti-mildew performance.

Description

technical field [0001] The invention belongs to the field of polymer composite materials. In particular, it relates to an environment-friendly polyurethane elastomer / nano composite material and a preparation method thereof, and is mainly used for laying sports grounds. Background technique [0002] Regarding the laying of sports venues, in 1961, the American 3M Company first laid a horse racing track with polyurethane materials; in the 19th Olympic Games in 1968, the track and field track was officially laid with polyurethane paving materials produced by 3M Company (called "Tartan") Runway), has been internationally recognized as the best playing field, and has been widely used. In the 1980s, track and field tracks paved with polyurethane also appeared in our country. For more than 20 years, the formula system similar to that adopted by the Chinese invention patent application publication number CN1033639A has been used, namely: the so-called TDI (toluene diisocyanate) (co...
