Novel anti-skidding coating for deck and preparation method thereof

Abstract

The invention provides a novel anti-skidding coating for a deck, which is composed of the following components in parts by weight: 30-45 parts of latex, 2-5 parts of film forming accessory ingredient, 15-25 parts of titanium pigment, 5-20 parts of filler, 0.2-1.0 part of wetting dispersant, 5-15 parts of anti-skidding agent, 0.1-0.5 part of de-foaming agent, 0.5-1.0 part of age inhibitor, 0.5-2.0 parts of thickening agent, 0.5-1.0 part of anti-mildew corrosion-protection agent, and 10-25 parts of water. The coating of the invention has very high wearing resistance and anti-skidding degree; the formed coat has good adhesive ability, wearing resistance, weather resistance, light-proof aging resistance, seawater resistance and salt mist resistance, wherein the artificial weathering aging test (ultraviolet UVB-313 resistance) is 4000 h, and the wearing resistance (1000g / 1000r) is not more than 30mg; the coating is applied to the corrosion prevention of the decks and the iron surfaces of the sea apparatus of boats and ocean platforms, wherein the decks and the iron surfaces require to have weather resistance, anti-skidding property, wearing resistance, and seawater corrosion resistance. The preparation method of the anti-skidding coating for the deck is simple in technology, low in cost and is performed without special apparatus.

Description

Technical field [0001] The invention relates to a preparation method of ship deck coating, in particular to a new type of deck anti-skid coating and a preparation method thereof, and belongs to the field of coatings. Background technique [0002] Common anti-slip coatings can be divided into the following three categories according to the type of anti-slip agent added: One type uses inorganic sand particles as anti-slip agents, such as silica sand, quartz sand, glass hollow beads, emery, ceramsite, crystalline alumina, etc. The characteristics of this type of anti-skid coating are: high friction, easy-to-obtain raw materials, and low cost. However, this anti-skid agent has a large proportion and is easy to precipitate when mixed with paint. When spraying the gun, you have to manually spread sand and clean up the unglued parts. Sweeping away the caked sand results in low construction efficiency and uneven sand grains. Although the initial friction is large, it is easy to wear...

Problems solved by technology

[0002] Common anti-slip coatings can be divided into the following three categories according to the type of anti-slip agent added: one type uses inorganic sand as an anti-slip agent, such as silica sand, quartz sand, glass hollow beads, emery, ceramsite, crystalline alumina, etc. The characteristics of this type of anti-slip coating are: high friction, easy to obtain raw materials, and low cost. However, this anti-slip agent has a large specificity, and it is easy to precipitate when mixed with the paint. If the spray gun is blocked, artificial sanding must be used to deal with the aftermath. Sweep away the knotted sand, the construction efficiency is low, and the sand particles are uneven. Although the initial friction is large, it is easy to wear and fall off later, and the service life is short; the second type of anti-slip agent uses organic compound pellets, such as synthetic resin and waste rubber particles. Although the price of the non-slip agent is higher than that of inorganic granules, it has suitable hardness and elasticity, no sharp edges and corners, can withstand friction and impact, is not easy to break, has good adhesion, and is not easy to fall off. Compared with inorganic granules, the initial friction is a little smaller, but the service life Long, and the specific gravity is similar to the base material, not easy to settle, easy to apply, suitable for spraying, uniform pellets, but it is necessary to prevent the swelling and delamination of pellets and solvents; the third type of anti-slip coatings does not use anti-slip agent pellets, It is mainly to carry out molecular design on the base resin of the coating, and the highly active group components will generate strong polarity on the surface of the paint film, and the surface contact will generate movement resistance. This anti-slip coating is currently in the trial stage

The current anti-skid coatings are difficult to meet the use requirements of ship decks. The main disadvantages are: poor weather resistance and easy aging; complex construction, polluting the environment during the construction process and low construction efficiency; poor adhesion and corrosion resistance; resistance to alternating cold and heat poor sex etc.
