Problems solved by technology

Not only that, as an interior wall material, it is difficult to meet the requirements of national or industry standards in terms of flexural strength, impact strength, dry shrinkage rate, wet expansion rate, screw holding force, and non-combustibility, which limits the Use of flame retardant board as interior wall material in actual production
At present, the cost of the existing flame-retardant, moisture-proof and environmentally friendly interior wall panels is relatively high, which affects the popularity of interior wall panels. Therefore, people need a flame-retardant, moisture-proof, and environmentally friendly interior wall panels with a relatively simple structure and low cost.

Embodiment 1

[0032] A preparation method of an environment-friendly fireproof inner wall material is characterized in that, it is realized according to the following steps:

[0033] Step (1): Add magnesium sulfate to water and mix and stir to make a magnesium sulfate solution, and send it into a blender. The above calculations are 5 parts by weight of magnesium sulfate and 5.5 parts of water;

[0034] Step (2): Magnesium oxide, calcium stearate, citric acid monohydrate, sodium citrate, calcium phosphate and bamboo chips are weighed and measured in turn, put into the batching bin, transported to the mixer and stirred with the magnesium sulfate solution for 15 -20min; add bentonite, fly ash, talcum powder in turn and continue to stir for 10-15min to form a slurry, the above-mentioned magnesium oxide by weight is 10 parts, citric acid monohydrate 0.1 part, sodium citrate 0.08 part, calcium phosphate 0.15 part , 0.1 part of calcium stearate, 2 parts by weight of bamboo chips in the filling mat...

Embodiment 2

[0040] A preparation method of an environment-friendly fireproof inner wall material is realized according to the following steps:

[0041] Step (1): Add magnesium sulfate to water and mix and stir to make a magnesium sulfate solution, and send it into a blender. The above-mentioned calculation by weight is 5.5 parts of magnesium sulfate and 6 parts of water;

[0042] Step (2): Magnesium oxide, calcium stearate, citric acid monohydrate, sodium citrate, calcium phosphate and bamboo chips are weighed and measured in turn, put into the batching bin, transported to the mixer and stirred with the magnesium sulfate solution for 15 minutes Add bentonite, fly ash, and talcum powder successively and continue to stir for 15 minutes to form a slurry.

Abstract

A preparation method of an environment-friendly fireproof interior wall material, characterized in that: the environment-friendly fireproof interior wall material is formed by reacting magnesium oxide, magnesium sulfate and water, and is formed with monohydrate citric acid, sodium citrate, calcium phosphate, stearic acid Calcium is used as an additive, and bamboo chips, bentonite, fly ash, talcum powder, etc. are used as auxiliary filling materials to make slurry, combined with medium-alkali or low-alkali glass fiber gray cloth and non-woven fabric, and distributed on the upper and lower surfaces respectively , adding slurry in the middle, roll forming, and then curing and demoulding. The raw materials used in the present invention are safe and environmentally friendly, and the formaldehyde emission of the prepared environmentally friendly fireproof inner wall material is as low as 0.1ml / L, which is lower than the EU standard. No moisture, no water drops, that is, no anti-halogen phenomenon, good moisture resistance, dry shrinkage rate of 0.1%, wet expansion rate of 0.1%, good dimensional stability of the board, good sulfate resistance of the material, and not easy to be corroded , the material has good adhesion and is easy to color.

Description

technical field [0001] The invention belongs to the field of building material preparation, and in particular relates to a preparation method of an environment-friendly fireproof interior wall material. Background technique [0002] Interior wall panels are a kind of decorative building panels commonly used in home decoration. At present, the commonly used interior wall panels are mainly wooden interior wall decoration materials, which are prone to frequent fire accidents and seriously threaten the safety of people's lives and property. Wood-based wood-based panels belong to Flammable materials, the combustion process releases a large amount of heat, spreads quickly, and can also release toxic smoke, so the fire hazard is great; and it is easy to be distorted and deformed during use, and the board surface will change color, pulverize, and crack due to moisture , The adhesion of the board is not good when it is used, and the shedding phenomenon is very serious. Therefore, in...
