Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an anti-cracking PE primer and its preparation method, which has the advantage of wider applicable temperature, and solves the problem that the PE primer can only guarantee the anti-cracking function at normal temperature. When the value is too low, the number of cracks of the PE primer will gradually increase, which will affect the function of the PE primer

Abstract

The present invention discloses an anti-cracking PE primer and a preparation method thereof. The anti-cracking PE primer is prepared from the following raw materials in parts by weight: 50-60 parts ofPE resin, 5 parts of zinc stearate, 20 parts of transparent powder, 0.5 part of anti-settling agent, 0.3 part of dispersing agent, 0.2 part of defoaming agent, 0.4 part of leveling agent, 0.1-0.5 part of polymerization inhibitor, 10-15 parts of nano micro-bead, 10 parts of styrene, 9 parts of methylbenzene, 9 parts of ethyl acetate, 1-1.5 parts of blue water, and 1-1.5 parts of white water. The anti-cracking PE primer and the preparation method thereof are characterized in that the strength of the PE primer can be enhanced by adding an appropriate amount of nano micro-bead, thus allowing foran improvement in the deformability of the material; the PE primer has better anti-cracking capability in a low-temperature environment and therefore is suitable for a low-temperature severe environment; and the original excellent properties of the PE primer are not changed after an appropriate amount of nano micro-bead is added. The anti-cracking PE primer has good coating effect and excellent cracking resistance, and can be widely used in furniture coating; and no waste gas is produced to pollute the environment during the preparation of the PE primer.

Description

technical field [0001] The invention relates to the field, in particular to an anti-cracking PE primer and a preparation method thereof. Background technique [0002] PE paint is unsaturated polyester paint, which is cured by the blending of the main agent, accelerator and initiator for polymerization and bridging reaction. The solvent is styrene, which participates in the reaction when forming a film. Compared with solvent-based wood paint , the advantage of PE paint is that it has "100% reactivity", which means that the liquid composition can be completely transformed into a solid polymer without the release of by-products under the action of the initiator, while the solvent paint requires a large amount of solvent After volatilization, the paint film can be formed. Such a paint film is not as hard as the resin curing molding, and the volatilization of the solvent has caused certain environmental pollution and brought health damage to the construction workers. In addition,...
