Photocuring hammer paint

Abstract

The invention discloses photocuring hammer paint. The photocuring hammer paint comprises components in percentage by weight as follows: 15-25% of thermoplastic organic silicone modified alkyd resin, 5-25% of phenolic epoxy acrylic resin, 15-30% of UV (ultraviolet) curing monomers, 1-5% of a photoinitiator, 35-45% of a solvent, 0.5-1% of a hammer additive and 2-4% of non-floating type aluminium powder. According to the photocuring hammer paint, the UV curing components are introduced into the hammer paint, so that the film formation and curing time is shortened, and the construction efficiency is improved; and the UV curing components are introduced, through a photocuring chemical crosslinking reaction, the crosslinking density of a paint film is increased, the heat resistance and the abrasion resistance of the paint film are improved, and the phenolic epoxy acrylic resin in the paint has the excellent chemical resistance, so that the hammer paint has the better chemical resistance, corrosion resistance and temperature variation resistance and can satisfy the requirements of hammer decoration on surfaces of instruments in current aviation and navigation fields for resistance.

Description

technical field [0001] The invention relates to a paint, in particular to a photocurable hammer paint. Background technique [0002] Hammer paint is so named because the paint film resembles the pattern of light reflection after hammering the metal surface. Due to the unevenness of the surface of the hammer paint and the irregular reflection of light, the surface after spraying has a pattern with a strong three-dimensional hammering shape, which can cover up defects such as uneven surface of the product. During construction, as long as the painted surface is relatively flat, the requirements can be met, which relatively reduces the workload of paint construction personnel to apply putty. With the development of modern coating technology, hammer paint has been widely favored by people for its clear hammer pattern, beautiful and unique, good three-dimensional effect and uniform distribution, and has gradually become a commonly used decorative paint in the field of surface coa...

Problems solved by technology

Under the catalysis of toluenesulfonic acid, the domestic methyl etherified melamine formaldehyde resin selected by the hammer paint can produce bright luster, strong hardness, high flexibility and good weather resistance when cured, but its curing time is relatively long, and the formaldehyde Free formaldehyde contained in etherified melamine formaldehyde resin will pollute the environment
