Abstract

The invention provides polyurethane glue for an environment-friendly sports field and a preparation method of the glue. The glue comprises 30%-60% of polyether polyol, 5%-15% of diphenyl methane diisocyanate, 5%-10% of thermoplastic resin, 3%-7% of modified zeolite, 10%-25% of an auxiliary, 3%-10% of castor oil and 5%-10% of nano inorganic filler, wherein the inorganic filler comprises alumina micro powder and white carbon black nano micro capsule powder in the weight ratio being 1:(1.5-2). With the adoption of the preparation method, the production and construction environments are improved, the solidification time of the glue is shortened, the technological process is simple, the organic coordination of soft and hard chains after shaping of the glue is guaranteed, molecular arrangement between phases can be realized well, the glue has good elongation rate and the elongation strength is improved.

Description

technical field [0001] The invention relates to the field of sports, in particular to an environmentally friendly polyurethane glue for sports venues and a preparation method thereof. Background technique [0002] In 1968, polyurethane adhesives were used for the bonding of glass fiber reinforced plastics. After the improvement of the two-component polyurethane packaging and the use of one-component polyurethane adhesives in 1978, the development of polyurethane adhesives was accelerated. With the development of our country's national fitness campaign, the use of polyurethane adhesives is showing a trend of vigorous development. [0003] Polyurethane glue is a semi-finished product of organic synthesis calculated by the equivalent ratio of polyether and isocyanate. At present, in the actual use of most plastic runway glues, due to differences in the selection of raw materials, proportioning and synthesis processes when designing formulas, the mechanical properties and const...
