Abstract

The invention belongs to the technical field of polyurethane, and particularly relates to a quick-curing silicon PU material and a preparation method thereof. The quick-curing silicon PU material is composed of a component A and a component B, wherein the component A is composed of polyether polyol, a filler, a plasticizer, a chain extender, a pigment, an ultraviolet absorber, an antioxidant, a catalyst, a defoamer and a thixotropic additive, the component B is composed of polyether polyol, isocyanate and a storage stabilizer, and the mass ratio of the component A to the component B is 4-6: 1.According to the quick-curing type silicon PU material, the curing speed of silicon PU is increased, construction is convenient, the construction efficiency is improved, good wear resistance and flexibility are achieved, and the problem that a traditional silicon PU material is long in construction period is effectively solved; the invention also provides the preparation method thereof.

Description

technical field [0001] The invention belongs to the technical field of polyurethane, and in particular relates to a fast-curing silicon PU material and a preparation method thereof. Background technique [0002] Silicon PU material is a new generation of stadium paving material developed on the basis of traditional PU stadium materials. Because of its good cushioning, ductility, wear resistance, etc., it is widely used in the construction of basketball courts, badminton courts, tennis courts and other sports venues. Silicon PU materials effectively solve the deficiencies of PU court materials in terms of professional performance, environmental protection construction, service life, daily maintenance, etc., and are revolutionary innovations. However, at present, silicon PU has high requirements in construction, the viscosity of the material liquid is high, and the curing time is long. Generally, the next step of construction can only be carried out after 24 hours, which grea...
