Problems solved by technology

The main advantages of epoxy resin floor coatings are high hardness and good acid and alkali resistance. However, its disadvantages are: because epoxy resin is a rigid material, its wear resistance, low temperature resistance, surface scratch resistance, weather resistance, etc. Poor performance, easy aging and short service life
At present, most polyurethane floor coatings on the market are solvent-based, and solvent-based polyurethane floor coatings also contain a certain amount of free isocyanate monomers, which will seriously affect people's health and living environment during construction.
In addition, solvent-based polyurethane floor coatings will be affected and restricted by ambient temperature and humidity, grass-roots humidity, and other problems on the base surface. Difficult to satisfy
Therefore, there will be many disadvantages that are difficult to overcome during construction, such as: foaming, bubbling, shedding, poor adhesion, etc., which affect the protective effect of floor coatings
[0003] A self-closing polyurethane waterproof coating with application number 201510959502.1 and its production process. The polyurethane waterproof coating uses 1,6-hexamethylene diisocyanate, 2,6-diisocyanatocaproic acid methyl ester and polycaprolactone polyol The main component A base material is made of HTPB, calcium-based bentonite and diethylene triamine-based component B base material, which has good self-closing waterproof performance and strong adhesion, but the polyurethane The chemical resistance, stability and anti-skid performance of waterproof coatings are lacking and the curing speed is slow at room temperature; It is easy to cause problems such as cracking of the polyurethane floor coating bonded to the base layer due to some stress concentration

Description

technical field [0001] The invention belongs to the technical field of floor coatings, in particular to polyurethane textured anti-slip floor coatings. Background technique [0002] More than 80% of domestic floor coatings are epoxy floor coatings, which are the most mature technology and the largest proportion. Epoxy flooring is based on epoxy resin, adding curing agent, thinner, dispersant, defoaming agent Agents and some fillers are mixed and processed. The main advantages of epoxy resin floor coatings are high hardness and good acid and alkali resistance. However, its disadvantages are: because epoxy resin is a rigid material, its wear resistance, low temperature resistance, surface scratch resistance, weather resistance, etc. Poor performance, and easy aging, short service life. The properties of polyurethane materials are as widely adjustable as epoxy resins, and their hardness, flexibility, resistance to organic acids and organic solvents are also very superior. Com...
