Abstract

The invention provides a solvent-free picking finish paint which comprises the following components in percentage by weight: 20-40% of epoxy resin, 1-5% of modified gas-phase silicon dioxide, 20-50% of pigment and filler, 1-10% of assistant and 20-40% of curing agent. The friction factor is increased by changing the surface condition of the paint film, thereby achieving the effects of skid prevention, environmental protection, decoration protection and fouling resistance; and the invention solves the problems of rough surface, complex construction and high cost in the existing product.

Description

technical field [0001] The invention relates to a floor paint, and more specifically relates to a solvent-free brushed finish paint. Background technique [0002] At present, the floor paint used more on the market is self-leveling epoxy floor paint. Although this floor paint has the advantages of convenient construction, environmental protection, cleanliness, and stain resistance, its surface friction coefficient is low and cannot achieve high Good anti-slip effect. For this reason, in order to achieve the anti-slip effect, the common practice now is to add quartz sand to the self-leveling epoxy floor paint to make a rough surface to achieve the anti-slip effect, but this method has a rough surface and poor cleaning performance. At the same time, the construction is cumbersome and the cost is relatively high. Contents of the invention [0003] In order to solve at least one of the above-mentioned problems of rough surface, poor stain resistance, cumbersome construction ...
