Abstract

The invention relates to a solvent-free single-component wet-curing polyurethane court elastic material sizing agent and preparation method. The sizing agent is prepared by adopting the following raw material formula: 25 to 40 parts of polyurethane pre-polymer with an end sealed by NCO, 20 to 45 parts of inorganic packing, 10 to 15 parts of plasticizer, 8 to 12 parts of viscosity reducer and 10 to 25 parts of functional additive; the polyurethane pre-polymer with the end sealed by the NCO is a reaction product of polyether glycol and excessive diisocyanate. According to the sizing agent prepared by adopting the formula and a process provided by the invention, the weakness that an existing material needs to be diluted by adding an organic solvent so as to be used can be solved; the sizing agent contains no organic solvent, thereby being small in viscosity, good in self leveling performance and convenient for construction; meanwhile, the solvent pollution during the material production, field construction and field application processes can be avoided, and the environmental friendliness can be realized; moreover, no organic solvent is contained, thus fewer material is used for per unit construction area of the same thickness, and the cost is saved.

Description

technical field [0001] The invention relates to a court elastic material slurry and a preparation method thereof, in particular to a solvent-free one-component moisture-cured polyurethane court elastic material slurry and a preparation method thereof. Background technique [0002] In recent years, with the rise of the sports industry, the sports field laying industry has developed rapidly. Polyurethane materials have also been greatly developed as excellent sports ground paving materials. The use of traditional two-component polyurethane paving materials requires on-site measurement and mixing, which is laborious and prone to errors, and requires high requirements for construction workers. [0003] In 2005, Jiangmen Changhe Group launched a silane-modified one-component polyurethane flooring material and named it Silicon PU. The material has good cushioning and ductility, strong adhesion, has a certain healing function on the foundation, can be automatically leveled, simpl...
