Plastic sizing agent for silane-modified single component wet cured polyurethane playing court and preparation method thereof

Abstract

The invention relates to plastic sizing agent for a silane-modified single component wet cured polyurethane playing court; the plastic sizing agent comprises 7 to 11% of isocyanate, 25 to 40% of polyether polyol A, 1 to 3% of polyether polyol B, 10 to 20% of dissolvant, 20 to 40% of solid filler, 5 to 25% of plasticizer, 0.1 to 5% of silane coupling agent, 0.4 to 2% of pigment, 0.1 to 2% of anti-aging agent, 0.1 to 2% of ultraviolet absorbent, 0.1 to 1% of water, 0.001 to 0.1% of catalyst and 0.001 to 0.1% of polymerization inhibitor. The plastic sizing agent for a silane-modified single component wet cured polyurethane playing court is suitable for basketball courts and indoor venues, is convenient to use, does not need to be blended, and has stronger cohesive force with bottom foundations and low requirements on environment moisture; and after the plastic sizing agent is modified by the silane coupling agent, all indexes of the plastic sizing agent are superior to national standard.

Description

technical field

[0001] The invention relates to the preparation and application method of a new type of silane-modified polyurethane plastic slurry. Background technique

[0002] Traditional two-component polyurethane slurry needs to be prepared and applied at any time, and the storage time should not be too long. Mixing and metering take man-hours and increase the construction cost. Mistakes are inevitable when mixing and metering before use, and the construction is harmful to the environment. The temperature and humidity requirements are relatively high. Compared with the traditional two-component polyurethane slurry, the one-component silane-modified moisture-curing polyurethane slurry is easy to use, does not need to be mixed, greatly reduces the construction time and construction cost, and reduces the influence of human factors on the quality of the project, without stoichiometric , no need to add cross-linking agent, it can be cured by using air or moisture on the sur...
