Abstract

The invention relates to a polyurethane plastic material, which is prepared from the following raw materials by mass: 35-55wt% of polyether polyol; 7-15wt% of isocyanate; 10-20wt% of a plasticizer; 15-25wt% of an inorganic filler; 1-3.0wt% of a colorant; 0.5-2.0wt% of a wetting dispersant; 0.1-3.0wt% of an antioxidant; 1-5wt% of oxazolidine; and 0.1-2wt% phosphoric acid. The invention also discloses a preparation method of the polyurethane plastic material, and the method comprises the following steps of: (1) adding polyether polyol and additives into a reaction kettle, performing dehydratinguntil the water content of the system is lower than 0.05%, and conducting cooling; (2) adding isocyanate, carrying out reaction for 2-3h, and carrying out dehydration and cooling; (3) adding oxazolidine and phosphoric acid; and (4) uniformly mixing the product with water and a catalyst, and conducting flattening and curing to obtain the polyurethane plastic material. The polyurethane plastic material prepared according to the invention has a stable micropore structure and unshrinkable foam pores, is convenient to construct and has low requirements on construction conditions.

Description

technical field [0001] The invention relates to a polyurethane plastic material and a preparation method thereof, belonging to the technical field of polyurethane plastic venues. Background technique [0002] In recent years, the use of polyurethane plastic materials has become more and more common, and the laying sites include stadiums, schools, public fitness places, etc. The plastic material has a certain hardness and good flatness. The introduction of a closed microporous structure in it can absorb shocks, play a cushioning effect, protect the athletes' joints, reduce the risk of injury, and increase the elasticity of the material, which helps to improve sports performance. [0003] The laying of traditional polyurethane plastic sites generally adopts the method of two-component construction. The process of two-component construction requires operators to mix ingredients at the construction site. During the operation of ingredients, the ratio of the two components is pro...
