Problems solved by technology

[0002] Existing PU paint products not only generally have the problem of solvent residue after paint construction, but also have low filling performance, low hardness, and cannot form a film at one time. They have high requirements for the construction environment, thus reducing production efficiency and increasing construction costs.

Abstract

The invention relates to unsaturated polyester black backing varnish with high fillibility and a preparation method thereof. The black backing varnish is prepared from a main agent, a promoter, an initiator and a diluent according to a weight ratio of (90-110): (0.9-1.1): (1.1-1.3): (25-30), wherein the main agent is prepared from the following raw materials in parts by weight: 35-50 parts of unsaturated resin, 0.5-1 part of dispersant, 0.1-0.3 part of non-silicon flatting agent, 0.5-0.8 part of carbon black, 0.1-2 parts of zinc powder, 30-45 parts of talcum powder, 10-20 parts of styrene and 0.1-0.2 part of polymerization inhibitor; the promoter is cobalt naphthenate; the initiator is cyclohexanone peroxide; the diluent is styrene. The unsaturated polyester black backing varnish prepared by the preparation method disclosed by the invention not only has high fillibility and high hardness, but also is capable of improving the fullness of finishing coat, and no solvent is rest on the varnish films after the construction, so that the environmental tolerance of the construction is large.

Description

technical field [0001] The invention relates to a black primer and a preparation method thereof, in particular to a highly filling unsaturated polyester black primer and a preparation method thereof. Background technique [0002] Existing PU paint products not only generally have the problem of solvent residue after paint application, but also have low filling performance, low hardness, cannot form a film at one time, and have high requirements on the construction environment, thus reducing production efficiency and increasing construction costs. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art, the invention provides a kind of highly filling unsaturated polyester black primer and preparation method thereof, the unsaturated polyester black primer prepared by the present invention not only has high filling, High hardness can improve the fullness of the topcoat, and there is no solvent residue in the paint film after...
