AI Technical Summary

Problems solved by technology

Sprayed fire retardant coatings not only have the above-mentioned shortcomings of environmental pollution and high cost, but also have inconsistent properties with the plastering mortar, and the interface is quite different, which may easily lead to interface defects and cause quality problems.
On the one hand, the flame retardant of non-woven composite board further increases the cost, and it is easy to fall off, which is not conducive to recycling

Embodiment Construction

[0020] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0021] (1) The common ash of 300 mass parts, the fine sand of 500 mass parts, the rubber powder of 30 mass parts, the wood fiber of 3 mass parts, the cellulose ether of 2 mass parts, the talcum powder of 4 mass parts and 40 mass parts Add the fireproof powder into the container in turn, and stir at the same time, so that the whole system is finally mixed evenly;

[0022] (2) Add 500 parts by mass of water to the homogeneously mixed system prepared in step (1), while stirring to make the homogeneously mixed system.

[0023] Among them, the common ash is PSB32.5 from Zhenxing Cement Plant.

[0024] The fine sand is 40-70 mesh from Xuri Sand Factory.

[0025] Rubber powder selects 5044 of Wacker Company of Germany for use.

[0026] The cellulose ether is selected from the cellulose ether hpmc100000 of Sanwei Chemical Company.

[0027] The fire re...

Abstract

The invention discloses an environment-friendly flame-retardant mortar, which is composed of 200-400 parts by mass of ordinary ash, 300-900 parts by mass of fine sand, 10-50 parts by mass of rubber powder, 1-5 parts by mass of wood fiber, 1-5 parts by mass of cellulose ether, 20-60 parts by mass of fireproof powder, 2-5 parts by mass of talc powder and 300-860 parts by mass of water. The above components are mixed and stirred evenly during preparation, the environment-friendly flame-retardant mortar evenly coats a heat-insulation board when used, the environment-friendly flame-retardant mortaris not only effective in flame retardance and convenient in construction, but also can effectively combine with a plastering mortar to avoid interface defects.

Description

technical field [0001] The invention relates to a fireproof material, more specifically, to an environment-friendly flame-retardant mortar and its preparation method and application. Background technique [0002] Fire has become one of the major disasters that endanger human life and property safety. Various bamboo and wood structure buildings are flammable buildings. Various concrete and steel structure projects will either burst or lose strength and collapse at high temperatures above 300°C. Therefore, people develop a variety of inorganic and organic fireproof coatings, which are sprayed on the surfaces of civil structures, concrete and steel structures to protect them from fire and avoid or reduce losses caused by fire. [0003] There are many kinds of fire retardant coatings. According to their composition, they can be divided into inorganic fire retardant coatings based on inorganic salts and organic fire retardant coatings based on natural or artificial resins. Accord...
