Problems solved by technology

[0003] 1. The bending resistance is poor, and the bending resistance is only 0.75 to 1.2 times the weight of the partition wall;
[0004] 2. The partition board is easily distorted and deformed;
[0005] 3. The water resistance of the partition board is poor, and the partition board will return to moisture after it rains;
[0006] 4. After the partition board is installed, a layer of oxide film will be formed on the surface of the board body. After the board body is painted, the whitewash layer will turn yellow and fall off easily;
[0007] 5. The expansion and contraction rate of the partition wall panel is large. After installation, there will be cracks between the partition wall panel and the partition wall panel, which makes the installation not up to standard

Abstract

The invention relates to a high-performance concrete extrusion partition plate, which is made from the following ingredients of: by weight, 200 parts of cement, 200-300 parts of flay ash, 400-600 parts of waste stone flour, 3-5 parts of mekralon, 30-50 parts of vegetable fiber, 60-80 parts of an inorganic water-retaining agent, 2-3 parts of a rare earth catalyst and 150-200 parts of tap water. A preparation method of the high-performance concrete extrusion partition plate comprises the following steps of: raw material preparation, raw material mixing and stirring, extrusion by a high-pressure vacuum extruder, autoclave curing and setting high-pressure curing. The high-performance concrete extrusion partition plate provided by the invention has characteristics of energy conservation, no pollution, high compressive strength, good water resistance, aging resistance, low expansion and contraction, distortion and deformation resistance, water tightness, fire protection and sound insulation. In addition, the yellowing and shedding phenomena of the partition plate can be eliminated.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-performance concrete extruded partition wall board and a preparation method thereof. Background technique [0002] At present, there are various kinds of partition boards used in the market. According to the research, the disadvantages are as follows: [0003] 1. The bending resistance is poor, and the bending resistance is only 0.75 to 1.2 times the weight of the partition wall; [0004] 2. The partition board is easily distorted and deformed; [0005] 3. The water resistance of the partition board is poor, and the partition board will return to moisture after it rains; [0006] 4. After the partition board is installed, a layer of oxide film will be formed on the surface of the board body. After the board body is painted, the whitewash layer will turn yellow and fall off easily; [0007] 5. The expansion and contraction rate of the partition board is large....
