Abstract

The invention discloses a water-soluble acrylic resin coating and a preparation method thereof. The preparation method comprises the following steps of weighting hydroxyethyl methacrylate, chlorinated polyethylene, methyl methacrylate, butyl methacrylate, monobutyl maleate, butyl acrylate, styrene, diethylaminoethyl methacrylate, azobisisobutyronitrile, methylbenzene, a crosslinking agent, hexahydrophthalic anhydride, methanol 1 and a plasticizer; adding hydroxyethyl methacrylate, chlorinated polyethylene, methyl methacrylate and butyl methacrylate into a reaction kettle; stirring while heating; then, adding styrene, methanol and azobisisobutyronitrile; recovering methanol; adding monobutyl maleate and methylbenzene; adding the rest raw materials, and grinding to obtain the water-soluble acrylic resin coating. The water-soluble acrylic resin coating has the viscosity of 60-80s, the adhesive force of 1-2 grades and the hardness of 0.55-0.75; the impact strength is 45-65kg / cm, the tack-free time is 30-50min, and the solid drying time is 4-6h; a coated film has no bubbling and winkling phenomena after being soaked in a saturated calcium hydroxide solution for 7-14d and has no falling and bubbling phenomena after being soaked in water for 15-30d; the water-soluble acrylic resin coating has the flexibility of 2-4mm and can be widely produced and used for continuously replacing the traditional material.

Description

technical field [0001] The invention relates to a coating, in particular to a water-soluble acrylic resin coating and a preparation method thereof, belonging to the technical field of water-soluble coatings. [0002] Background technique [0003] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called a...
