Problems solved by technology

[0003] In addition, at present, as a roofing material for waterproofing, heat preservation and heat insulation, clay tiles are one of the roofing materials that we use more and have a longer history. However, such tiles need to consume a large amount of clay. Environment, energy conservation, need to develop new tile materials

Embodiment 1

[0038] Straw tiles are prepared by the following steps:

[0039] (1) Straw crushing treatment: cut the rice straw into small pieces of 27-30mm, then sieve to remove the broken leaves and silt, and then put it into a pulverizer for crushing, and get the crushed material after screening, and get the rice after drying Straw raw materials for standby;

[0040] (2) adding the modified polyacrylic resin to a screw extruder to extrude and granulate to obtain the raw material of the modified polyacrylic resin for later use;

[0041] (3) Preparation of straw tiles by hot pressing: Treated rice straw: 30 parts, modified polyacrylic resin: 20 parts, and fly ash: 20 parts; calcium carbonate: 5 parts; antioxidant 1010: 2 parts; Silicone flame retardant: 1 part; calcium sulfoaluminate: 1 part; isocyanate: 3 parts mixed, hot-pressed at a temperature of 160 ° C, the pressure of hot pressing is 2.5Mpa, and then obtained after cooling and demoulding Rice straw tiles.

Embodiment 2

[0043] Straw tiles are prepared by the following steps:

[0044] (1) Straw crushing treatment: cut soybean straw into small pieces of 20-22mm, then sieve to remove broken leaves and silt, and then put them into a crusher for crushing, and obtain crushed materials after screening, and obtain soybeans after drying Straw raw materials for standby;

[0045] (2) adding the modified polyacrylic resin to a screw extruder to extrude and granulate to obtain the raw material of the modified polyacrylic resin for later use;

[0046] (3) Preparation of straw tiles by hot pressing: 40 parts of processed soybean straw, 25 parts of modified polyacrylic resin, 10 parts of fly ash, 8 parts of calcium carbonate, 5 parts of antioxidant 1010; Organosilicon flame retardant: 3 parts; calcium sulfoaluminate: 3 parts; isocyanate: 5 parts, mixed, hot-pressed at 180°C, the pressure of hot-pressed is 3Mpa, and then cooled and demolded to obtain soybeans Straw tiles.

Embodiment 3

[0048] Straw tiles are prepared by the following steps:

[0049] (1) Straw crushing treatment: cut rice straw and wheat straw into small pieces of 25-30mm, then sieve to remove broken leaves and silt, then put them into a crusher for crushing, and obtain crushed materials after screening, and dry them Afterwards, straw raw materials are obtained for subsequent use;

[0050] (2) adding the modified polyacrylic resin to a screw extruder to extrude and granulate to obtain the raw material of the modified polyacrylic resin for later use;

[0051] (3) Preparation of straw tiles by hot pressing: Treated rice straw and wheat straw: 35 parts, modified polyacrylic acid resin: 25 parts, and fly ash: 15 parts; calcium carbonate: 6 parts; antioxidant 1010: 3 parts; silicone flame retardant: 2 parts; calcium sulfoaluminate: 2 parts; After molding, rice straw and wheat straw tiles are obtained.

Abstract

The invention discloses a straw tile. The straw tile is prepared from the following components in parts by weight: 30-40 parts of straws, 20-25 parts of modified polyacrylate, 10-20 parts of coal ashes, 5-8 parts of calcium carbonate, 2-5 parts of an antioxidant, 1-3 parts of a flame retardant, 1-3 parts of a water-proofing agent and 3-5 parts of an adhesive. The invention also discloses a preparation method of the straw tile. The straw tile disclosed by the invention not only can be used for retaining excellent characteristics of being heat-insulated, thermal-insulation, soundproof, warm in winter and cool in summer of the raw materials, but also has the characteristics of being resistant to corrosion, resistant to rust and non-deforming, can be used for substituting for the conventional color steel tiles, clay tiles, asbestos tiles and cement tiles, and has great application prospect.

Description

technical field [0001] The invention relates to a straw tile and a preparation method thereof, belonging to the technical field of tile production. Background technique [0002] Straw, the usual treatment method is incineration or burial. A large amount of incineration or burial will seriously pollute the environment. At present, my country has strictly restricted or even prohibited the burning or burying of straw. The reuse of straw has become a relatively hot research direction at present. [0003] In addition, at present, as a roofing material for waterproofing, heat preservation and heat insulation, clay tiles are one of the roofing materials that we use more and have a longer history. However, such tiles need to consume a large amount of clay. Environment, energy conservation, need to develop new tile materials. [0004] Therefore, the organic combination of straw and tile materials has become the focus of research. Contents of the invention [0005] In order to so...
