Problems solved by technology

Asbestos tiles are restricted in use due to carcinogens; fiberglass tiles have aging defects, color steel tiles are easy to process and install, and are widely used, but they have disadvantages such as no heat insulation, no sound insulation, and easy oxidation and corrosion; cement tiles are also widely used. It is wide, but its capacity is large, and it is not easy to install.
Magnesite corrugated tiles are widely used in the field of building materials due to their good properties such as fire prevention, light weight and high strength, anti-corrosion, anti-aging, and easy construction. At present, the main raw materials for corrugated tiles are mainly produced in the In Liaoning, my country, due to the limitation of resources and regions, the cost of raw materials for the production of magnesite fireproof board decorative boards is relatively high, and it is not easy to promote

Embodiment 1

[0005] Example 1: A dolomite magnesium cement corrugated tile and its manufacturing method. Take 10 kg of caustic dolomite powder, 1.2 kg of magnesium chloride, 1 kg of sawdust, 0.5 kg of fly ash, 0.5 kg of expanded perlite, and 4.4 kg of water. The magnesium chloride and water Prepare a solution, mix the solution and other materials evenly in the mixer to make a slurry. After the slurry is made, it is poured into the plate-making machine board. At the same time, two layers of glass fiber mesh are laid, and the back is laid with a non-woven fabric. After the board is moved into the corrugated tile mold (1800×720×5mm), it is molded and cured for 18 hours at 10℃ and then demolded. After demolding, it is cured at 10℃ and the relative humidity of the air is less than 80% after indoor curing for 28 days. Natural dolomite magnesium cement corrugated tile.

[0006] The main technical indicators of the finished product are as follows:

Embodiment 2

[0011] Example 2: A dolomite magnesium cement corrugated tile and its manufacturing method. Take 10kg of caustic dolomite powder, 4kg of magnesium chloride, 6kg of crop straw powder, 3kg of talcum powder, 3kg of expanded vermiculite, 12kg of water, and make a solution of magnesium chloride and water , The solution and other materials are stirred evenly in the mixer to make a slurry. After the slurry is made, it is injected into the plate-making machine board. At the same time, two layers of glass fiber mesh are laid, and the back is placed with a non-woven fabric. In the corrugated tile mold (1800×720×5mm), it is molded and cured at 40°C for 24 hours and then demolded. After demolding, it is cured indoors at 40°C and air relative humidity less than 80% for 28 days. Use polyester The front of the paint sprayed corrugated tile, after the pigment is completely cured, it will become the finished colored corrugated tile.

Abstract

The invention relates to a dolomite magnesia cement pantile and a manufacturing method thereof, which belongs to the field of chemical and building materials. The dolomite magnesia cement pantile comprises caustic dolomite powder, magnesium chloride, a light filler, an inert filler, water and a thermal insulating material, the mass ratio of which is 1.00:0.12 to 0.40:0.10 to 0.60:0.05 to 0.30:0.44 to 1.20:0.05 to 0.30, and a supporting material is properly added. The manufacturing method comprises the following steps of slurry mixing, shaping, curing and maintaining. The produced dolomite magnesia cement pantile for buildings has the advantages of fire protection, thermal insulation, high strength, good water resistance, anticorrosion, shock prevention, easiness in construction, environmental protection, energy conservation, simple production process, low energy consumption and the like, is an updated product for replacing various color steel light partition wall boards, silicate cement partition wall boards and other boards, belongs to an environment-friendly building material and can be widely applied to the building industry.

Description

1. Technical Field [0001] The invention is a dolomite magnesium cement corrugated tile and a manufacturing method thereof, belonging to the field of chemical building materials 2. Background technology [0002] At present, the domestically produced corrugated tiles include asbestos tiles, FRP tiles, color steel tiles, cement tiles and so on. The use of asbestos tiles is restricted due to carcinogens; FRP tiles have aging defects, color steel tiles are easy to process and install, and are widely used, but they have the disadvantages of no heat insulation, no sound insulation, and easy oxidation and corrosion; cement tiles are also used It is wide, but its capacity is large and it is not easy to install. Magnesite corrugated roof tiles are widely used in the field of building materials with good performance such as fire resistance, light weight, high strength, anti-corrosion, anti-aging, and easy construction. At present, the main raw material for the production of corrugated roof...
