Abstract

The invention relates to the field of polyurethane sports grounds, in particular to a prefabricated polyurethane foamed elastomer material and a preparation method thereof, a field for construction and a construction method thereof. The prefabricated polyurethane foaming elastomer material is a two-component foaming polyurethane material, consisting of A component and B component; wherein A component is composed of polyether polyol, polymer polyol, foam stabilizer, talcum powder , color green, fumed white carbon black, diethanolammonium, ethylene glycol, water, and catalyst; B component is modified MDI; the ratio of A and B components is calculated according to the isocyanate index, and the isocyanate index is 0.7 -0.8. The prefabricated polyurethane foaming elastomer material of the present invention solves the problem of uneven foaming and bulging of cast-in-place foaming materials, has low water absorption and good cohesiveness; the stadium constructed by the present invention not only solves the problem of prefabricated It can solve the problem of poor flatness of the stadium, and also make the venue have better aging resistance and yellowing resistance.

Description

technical field [0001] The invention relates to the field of polyurethane sports grounds, in particular to a prefabricated polyurethane foamed elastomer material and a preparation method thereof, a field for construction and a construction method thereof. Background technique [0002] At present, most of the courts in various indoor and outdoor sports venues are still cast-in-place construction methods, and the promulgation of the new national standard GB / 36246-2018 restricts the impact absorption and vertical deformation performance of the court. In order to meet this performance requirement, most manufacturers When designing the formula, the material is designed to have a certain foaming rate, and this faces a problem, that is, the foaming rate of the material is different under different temperature and humidity environments, and under high temperature and high air humidity conditions, it is easy to cause The venue is bulging, affecting the quality of the venue. [0003]...
