A kind of novel deck antiskid coating and preparation method thereof

Abstract

The invention provides a novel deck anti-skid coating, which is composed of the following components in parts by weight: 30-45 parts of emulsion; 2-5 parts of film-forming aid; 15-25 parts of titanium dioxide; 5-20 parts of filler; 0.2-1.0 parts of dispersant; 5-15 parts of anti-slip agent; 0.1-0.5 parts of defoamer; 0.5-1.0 parts of anti-aging agent; 0.5-2.0 parts of thickener; share. The wear resistance and skid resistance of the present invention are very high, and its coating has excellent adhesion, wear resistance, weather resistance, light aging resistance, sea water resistance and salt spray resistance, wherein the artificial weather aging test (resistant to ultraviolet light UVB ‑313) reaches 4000h, wear resistance (1000g / 1000r) is not more than 30mg, can be used for ships, ocean platforms, etc., which need weather resistance, cloudy and slippery wear resistance, seawater corrosion resistant decks and other ocean facilities steel surface anticorrosion; The manufacturing method of the deck antiskid coating has simple process, no special equipment and low price.

Description

technical field [0001] The invention relates to a preparation method of a ship deck coating, in particular to a novel deck anti-skid coating and a preparation method thereof, belonging 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 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 ...

[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.
