Problems solved by technology

But its shortcomings are also obvious. The adjusted conventional transparent putty must be used up in a very short time. After a long time, it will solidify and lose its use value; it has a strong smell and is not environmentally friendly; in addition, the conventional transparent putty is used improperly. , will also cause problems such as poor adhesion of the upper layer of paint

Abstract

The invention provides water-based two-component transparent putty, which is composed of a component A and a component B in a weight ratio of 100: (1-5), and the component A comprises the following components in parts by weight: 15-30 parts of redispersible rubber powder, 0.2-0.8 part of a defoaming agent, 0.2-0.8 part of a wetting dispersant, 0.5-1.5 parts of a thickening agent, 30-65 parts of filler and 15-30 parts of water; and the component B is a diphenylmethane diisocyanate monomer or a prepolymer of the diphenylmethane diisocyanate monomer. According to the water-based two-component transparent putty, the redispersible rubber powder serves as a main film forming matter, water serves as a main solvent, the diphenylmethane diisocyanate monomer or a polymer of the diphenylmethane diisocyanate monomer serves as a hardening agent, and the water-based two-component transparent putty is excellent in filling property, good in construction performance, high in adhesive force and long in construction time limit; most importantly, no harm is caused to the health of constructors, and the water-based paint is a water-based environment-friendly product.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based two-component transparent putty and its application. Background technique [0002] Transparent putty, commonly known as automobile putty, is a fast-growing embedded filling material in the world in the past 20 years. It was first used in automobile coating, and now it has been developed to be widely used in wood coating industry. [0003] Conventional transparent putty is a kind of unsaturated polyester resin as the main raw material, mixed with additives such as cobalt salt initiator, polymerization inhibitor, pigment and filler, and peroxide as curing agent, which can be prepared and used at any time according to actual needs. A fast new type of filling material. For example, the publication number is a kind of fiber transparent putty of CN 1673299A, which is composed of main body ash and curing agent. The weight ratio of main body ash and curing agent is 100:2, wherein ...
