Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
A novel water-based vegetable oil-based polyurethane terrace coating comprises a resin component and a curing agent component;
the resin component comprises the following raw materials in parts by weight:
60-70 parts of water-based vegetable oil hydroxy resin;
8-10 parts of toner;
8-10 parts of barium sulfate;
2-5 parts of 1, 3-propanediol;
2-5 parts of dipropylene glycol methyl ether;
0.1-0.2 parts of thickening agent;
0.2-0.3 part of defoaming agent;

The invention adopts the water-based vegetable oil hydroxyl resin to replace the traditional hydroxyl acrylic resin, and the condensate is used as a pure polyurethane structure, has excellent hardness and weather resistance of the hydroxyl acrylic resin, and has better flexibility and high and low temperature resistance than the hydroxyl acrylic resin. The high-temperature wear-resisting floor paint has excellent high-temperature wear resistance, is applied outdoors, and can adapt to high-temperature use scenes with high ground temperature in summer and friction heating during automobile running.
Wherein the weight ratio of the resin component to the curing agent component is 2-10: 1. The curing agent component is HDI type water-based curing agent. The HDI type waterborne curing agent has the solid content of 79-81 percent and the NCO content of 16-17 percent, adopts aliphatic isocyanate and has excellent weather resistance.
The solid content of the water-based vegetable oil hydroxyl resin is 32-34%, and the solid content hydroxyl value is 1.7%. The invention changes the resin type, adopts the water-based vegetable oil hydroxyl resin with wear resistance, flexibility and high and low temperature resistance, and can keep good performance at the temperature of-10-120 ℃ when being cured and reacted with the isocyanate curing agent to generate a cured paint film.
The preparation method of the floor coating comprises the following steps:
step one, adding toner into the water-based vegetable oil hydroxyl resin according to a ratio, grinding, then adding barium sulfate, 1,3 propylene glycol, dipropylene glycol methyl ether, a thickening agent, a defoaming agent, a leveling agent and a wetting agent, stirring and dispersing, and adjusting the viscosity to a proper range.
And step two, before use, mixing the resin component and the curing agent component according to the proportion, and stirring uniformly for use.
In this example, paint films prepared from the similar product hydroxy acrylic resin, waterborne epoxy and paint films prepared according to the invention were used for high temperature abrasion resistance testing; comparing the friction loss amount by adopting a GB/T1768-2008 abrasion resistance test method (750g/500r) under the condition that the paint film is at 75 ℃:
water-based epoxy: 0.08 (middle)
Hydroxy acrylic resin: 0.12 (worst)
