Embodiment 1

[0009] First, weigh the components of the dry material according to the following proportions: 30% cement, 50% ground quartz powder, 10% coarse calcium, 4% wollastonite fiber, 4% PP fiber (polypropylene fiber), plasticized Agent 2%; Wherein, above-mentioned percentage is percentage by weight.

[0010] The raw materials are put into the mixer in order to stir, followed by cement, finely ground quartz powder, coarse calcium, wollastonite fiber, PP fiber and plasticizer. The ratio (weight ratio) of dry material to water consumption is 10:3; Filtration, vacuuming, molding, maintenance, and then painting, and finally packaging and inspection before leaving the factory.

[0011] The weight per square meter of the fiber cement roof tile prepared by the above method is below 24kg, and meanwhile, the effective area of ​​a single sheet of the fiber cement roof tile is 0.264 square meters.

[0012] In addition, the strength and other performances of the fiber cement roof tiles in this e...

Embodiment 2

[0015] First, weigh the components of the dry material according to the following proportions: 50% cement, 30% ground quartz powder, 5% coarse calcium, 6% wollastonite fiber, 6% PP fiber, and 3% plasticizer; , the above percentages are percentages by weight.

[0016] The raw materials are put into the mixer in order to stir, followed by cement, finely ground quartz powder, coarse calcium, wollastonite fiber, PP fiber and plasticizer. The ratio (weight ratio) of dry material to water consumption is 10:5; Filtration, vacuuming, molding, maintenance, and then painting, and finally packaging and inspection before leaving the factory.

[0017] The weight per square meter of the fiber cement roof tile prepared by the above method is less than 30 kg, and at the same time, the effective area of ​​a single sheet of the fiber cement roof tile is 0.264 square meters.

[0018] In addition, the strength and other performances of the fiber cement roof tiles in this example all meet or exce...

Embodiment 3

[0021] First, weigh the components of the dry material according to the following proportions: 35% cement, 35% ground quartz powder, 10% coarse calcium, 10% wollastonite fiber, 5% PP fiber, and 5% plasticizer; , the above percentages are percentages by weight.

[0022] The raw materials are put into the mixer in order to stir, followed by cement, finely ground quartz powder, coarse calcium, wollastonite fiber, PP fiber and plasticizer. The ratio (weight ratio) of dry material to water consumption is 10:5; Filtration, vacuuming, molding, maintenance, and then painting, and finally packaging and inspection before leaving the factory.

[0023] The weight per square meter of the fiber cement roof tile prepared by the above method is less than 27 kg, and at the same time, the effective area of ​​a single sheet of the fiber cement roof tile is 0.264 square meters.

[0024] In addition, the strength and other performances of the fiber cement roof tiles in this example all meet or ex...

Abstract

The invention discloses a fiber cement roof tile. The fiber cement roof tile comprises the following components in percentage by weight: 30 to 50 percent of cement, 30 to 50 percent of pulverized quartz powder, 5 to 20 percent of crude calcium and 10 to 20 percent of auxiliary additive, wherein the ratio of a dry material to water is 10:(3-5). The fiber cement roof tile product has high strength,light weight per unit area, and large single area; various properties such as strength can meet or exceed the requirement of 'Concrete Tile' JC / T 746-2007; the weight of the fiber cement roof tile per square meter is less than 30kg, while the weight of the common concrete tile per square meter is more than 45kg; meanwhile, the effective area of the single fiber cement roof tile is 0.264 square meter, while the effective area of the single common concrete tile is less than 0.1 square meter.

Description

technical field [0001] The invention relates to a fiber cement roof tile. Background technique [0002] Fiber cement roof tiles are widely used in roofing systems due to their light weight per unit area, high strength, and large single-sheet area. [0003] At present, fiber cement roof tiles widely used have problems such as large weight per unit area and small single-sheet area in order to ensure strength, which limits their use and increases the structural load of the roof. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a fiber cement roof tile with satisfactory strength and smaller specific gravity. [0005] In order to solve the above problems, the present invention provides a fiber cement roof tile, comprising the following components: 30-50% of cement, 30-50% of ground quartz powder, 5-20% of coarse calcium, and 10-20% of auxiliary additives %; the ratio of the above-mentioned dry material to water consu...
