Problems solved by technology

[0003] However, traditional polyurethane paints and UV paints are solvent-based paints. During the painting process, a large amount of toxic organic solvents and a small amount of free isocyanate monomers will be volatilized, which not only pollutes the operating environment, causes physical damage to operators, but also brings fire hazards. , and pollute the atmosphere

Embodiment 1

[0016] Example 1: Water-soluble floor paint resin, its production formula includes the following raw materials in parts by weight: 200 parts of castor oil; 90 parts of HDI; 100 parts of diethylene glycol; 55 parts of pentaerythritol; 35 parts of trimethylolpropane diallyl ether 70 parts of dimethylolpropionic acid; 2 parts of hypophosphorous acid; 9 parts of ammonia water; 180 parts of acetone.

[0017] The synthetic technique of present embodiment: throw castor oil, diethylene glycol, pentaerythritol, trimethylol propane diallyl ether, dimethylol propionic acid, hypophosphorous acid into four-necked flask, be warming up to 195~200 After esterification to an acid value of 55-65mgKOH / g at ℃, add ammonia water to neutralize, then add HDI to react at 80℃ for 3 hours, then dilute with acetone to obtain a water-soluble one-component floor oil resin.

Embodiment 2

[0018] Example 2: Water-soluble floor paint resin, its production formula includes the following raw materials in parts by weight: 185 parts of castor oil; 80 parts of HDI; 90 parts of diethylene glycol; 60 parts of pentaerythritol; 40 parts of trimethylolpropane diallyl ether 65 parts of dimethylol propionic acid; 1.5 parts of hypophosphorous acid; 10 parts of ammonia water; 180 parts of acetone.

[0019] The synthesis process of this embodiment is the same as that of Example 1.

Embodiment 3

[0020] Example 3: Water-soluble floor paint resin, its production formula includes the following raw materials in parts by weight: 180 parts of castor oil; 85 parts of HDI; 80 parts of diethylene glycol; 50 parts of pentaerythritol; 30 parts of trimethylolpropane diallyl ether 60 parts of dimethylolpropionic acid; 1 part of hypophosphorous acid; 8 parts of ammonia water; 183 parts of acetone.

[0021] The synthesis process of this embodiment is the same as that of Example 1.

Abstract

The invention discloses a water-soluble floor paint resin and an application thereof. A production formula of the water-soluble floor paint resin comprises the following raw materials of, by weight, 180-200 parts of castor oil, 80-100 parts of HDI, 60-100 parts of diethylene glycol, 50-60 parts of pentaerythritol, 30-40 parts of trimethylolpropane diallyl ether, 60-70 parts of dimethylolpropionic acid, 1-2 parts of hypophosphorous acid, 8-10 parts of ammonia water and 150-200 parts of acetone. Air drying monomers of trimethylolpropane diallyl ether are introduced in the water-soluble floor paint resin to form a dual-curing system with NCO groups, so that film hardness and wear resistance are increased greatly. The water-soluble floor paint prepared by using the water-soluble floor paint resin as a main component realizes low VOC, has no free isocyanate monomers and can meet the requirements of environmental performance, because water-soluble components are adopted during a construction process.

Description

technical field [0001] The invention relates to the field of paints and coatings, in particular to a resin for preparing floor paint and the floor paint using the resin. Background technique [0002] In the manufacturing process of the existing decorative floor, paint is often used as the coating on the surface of the product, and according to the characteristics of the manufacturing process of the decorative floor, polyurethane paint and UV paint are the preferred coatings, and the coating film formed by these coatings has higher Hardness and wear resistance, and can be used in assembly line, easy to operate. [0003] However, traditional polyurethane paints and UV paints are solvent-based paints. During the painting process, a large amount of toxic organic solvents and a small amount of free isocyanate monomers will be volatilized, which not only pollutes the operating environment, causes physical damage to operators, but also brings fire hazards. , and pollute the atmosp...
