Floor paint was first invented by Germany in 1934. It was mainly made of oil, tree material, color, solvent, etc. It was mainly divided into decorative floor paint, heavy anti-corrosion floor paint and heavy-duty floor paint. With beautiful, true, beautiful, wear-resistant, waterproof, anti-corrosion and other characteristics.
Product Categories:
1, heavy-duty
Ordinary concrete has poor impact resistance and wear resistance, and it is difficult to repair after surface damage. Therefore, it is often the case that floor paints with higher mechanical properties, such as pressure sand and mortar, are used as protective layers to increase the surface impact resistance and load carrying capacity. ability. For heavy machinery manufacturing, aircraft hangar, automobile manufacturing, automotive repair and other industries.
2, heavy anti-corrosion type
The ground used to contact chemical, corrosive chemicals such as acid, alkali and salt can effectively protect the concrete floor and prevent the chemical medium from infiltrating the cement floor. Vinyl ester heavy anti-corrosion floor paint, polyurethane, phenolic epoxy, vinyl resin and other paint varieties. Commonly used in electroplating, chemical, paper, food manufacturing and other industries.
3, anti-static type
Provide floor antistatic function, surface resistance of 2.5 × l04 ~ 1.0 × l09Ω, can effectively leak static charge, eliminate static electricity accumulation and electromagnetic interference hazards. According to the American Society for Testing and Materials (ASTM), anti-static flooring is divided into three types: the conductive floor (ECF, the surface resistance is 2.5 × l04 ~ 1.0 × 106Ω); static dissipative floor (DIF, the surface resistance It is 1.0×10 6 to 1.0×10 9 Ω) and the hard-to-be-static floor (ASF, whose surface resistance is 1.0×10 6 to 1.0×10 9 Ω). The commonly used coatings in China include solvent-based anti-static floor paints, solvent-free epoxy anti-static self-leveling floor paints, and conductive fibers used as conductive media. The conductive conductive mica powder, conductive zinc oxide, and other conductive fillers are used as conductive media. Solvent-free epoxy-conductive self-leveling floor paint. Has been widely used in electronics, precision instruments, powder manufacturing, military production and other fields in need of anti-static.
4, non-slip type
The glass transition temperature is lower than room temperature, and the elongation at break is more than 50%. After eliminating the external force, the coating has a better recovery performance.
The floor paint provides the floor with special functionalities and needs to be tested before use. The common varieties include impact-resistant spark floor paints made of wood chips, and polyurethane heat-resistant floor paints. It is used on the ground where the above performance is required in special occasions such as manufacturing of flammable and explosive dangerous goods.
Construction process:
1, floor surface treatment
(1) The newly completed industrial floor must undergo certain conservation before it can be constructed for approximately 28 days.
(2) Remove the surface of cement laitance, old paint, and attached debris.
(3) Thoroughly clean the surface of the oil and treat it with a degreasing agent.
(4) Remove stagnant water and thoroughly dry the tide.
(5) The surface cleaning must be done with a dust-free sweeper and a large vacuum cleaner.
(6) The flat surface is allowed to have a gap of 2 to 2.5 mm, a moisture content of less than 6%, and a pH of 6 to 80.
(7) The roughing of the surface of the floor needs to be done with a dustless grinder and thoroughly cleaned with a vacuum cleaner.
(8) Putty should be applied to the holes and obvious depressions on the surface of the floor to fill up the scrapings.
2, coating closed coating
(1) Apply a high-pressure airless spray or roller coater, epoxy sealer primer to treat clean, even surface of the crucible.
(2) Epoxy sealer has strong permeability. When applying the primer, a certain amount of thinner should be added so that the diluted primer can penetrate into the interior of the base layer to enhance the adhesion of the coating and the base layer. The cloth must be continuous and uninterrupted, and the amount of coating should be exactly saturated on the surface.
(3) Partial coating may be painted with a brush, and the excess primer on the surface must be polished before the next process.
3, coating the middle floor
(1) Finish the middle layer with epoxy floor coating on the surface of the polished and cleaned putty (20°C, 24 hours). The coating method can be applied by brush, scraping, high pressure airless spraying, large-area construction with high pressure without air Spraying is the best, spraying pressure is 20 ~ 25Mpa.
(2) This will make the ground more flat and easier to find defects still existing on the ground, so that the next level of construction leveling.
(3) This time also facilitates Party A's arrangement of equipment installation.
4. Finishing floor surface
(1) After the intermediate layer is dried, the epoxy floor coating is applied. The coating method is applied by scraping and high pressure airless spraying, but it is preferable to use high pressure airless spraying.
(2) Sanding and vacuuming should be performed on the intermediate layer with a sand bag type dustless rolling sander before painting.
(3) If Party A works in the intermediate layer, installation and adjustment of the equipment will be carried out first, which will cause new defects on the ground. The application of batch scraper will level and grind, and the surface shall be cleaned by vacuuming and cleaning.
Method of choosing:
1, wear resistance, floor paint most of the above is driving, stepping on people, so wear resistance must be better.
2, base case, the general value of compressive strength is greater than 20 on the line.
3, the choice of color. For different color designs, there are many colors for design requirements, as well as light and matt.
4, if you need to fire flowers, static discharge, you need to raise another.
