Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcoming existing in the prior art, and propose a kind of intumescent water-based fireproof coating, adopt propylene glycol, inorganic bentonite, ammonium polyphosphate, melamine, pentaerythritol, chlorinated paraffin, nanoscale titanium dioxide, hydroxyl The raw material of the fireproof coating is composed of ethyl cellulose, and the water reducer and ettringite powder are used as the mixed components of the expansion agent. The above raw materials are fully stirred or ground at a certain speed and at a suitable temperature, so that the raw materials are uniform Mixing, to crush the internal particles to the greatest extent, and the above-mentioned raw materials are all tasteless, so that the finished coating has no irritating smell, so that the staff will not feel uncomfortable during the spraying process, and at the same time the raw materials The ingredients are all non-toxic under the normal production process, and have no pollution to the external environment, which is in line with the concept of green production. At the same time, the coating performance after uniform grinding and mixing is relatively smooth, which increases the beauty of the sprayed product and improves the quality of the product. The effect of coating

Abstract

The invention discloses an intumescent water-based fireproof coating. The intumescent water-based fireproof coating comprises the following raw materials in parts by weight: 10 to 20 parts of propylene glycol, 20 to 30 parts of inorganic bentonite, 40 to 50 parts of ammonium polyphosphate, 25 to 35 parts of melamine, 15 to 35 parts of pentaerythritol, 30 to 40 parts of chlorinated paraffin, 10 to20 parts of nanoscale titanium dioxide, 25 to 35 parts of hydroxyethyl cellulose, 10 to 20 parts of a water reducing agent and 40 to 50 parts of ettringite powder. Compared with other treatment processes, the fireproof coating is prepared from a fireproof coating original material composed of propylene glycol, inorganic bentonite, ammonium polyphosphate, melamine, pentaerythritol, chlorinated paraffin, nanoscale titanium dioxide and hydroxyethyl cellulose. Meanwhile, a water reducing agent and ettringite powder are used as mixed components of the expanding agent, the raw materials are uniformly mixed, particles in the raw materials are ground to the maximum extent, the raw materials are odorless and do not pollute the external environment, the concept of green production is met, meanwhile,the uniformly ground and mixed coating is smooth in spraying performance, the attractiveness of a sprayed product is improved, and the using effect of the coating is improved.

Description

technical field [0001] The invention relates to the technical field of wallboards, and more specifically relates to an intumescent water-based fireproof coating. Background technique [0002] Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. It is applied to the surface of flammable substrates. It is used to change the combustion characteristics of the surface of the material to retard the rapid spread of fire; or to apply it to building components to improve the fire resistance limit of the special coatings, called fire retardant coatings. [0003] The existing fire retardant coatings have some disadvantages: the raw materials used in the existing fire retardant coatings are relatively simple, and the performance of fire prevention is also extremely limited. They can only blo...
