Energy-saving embedded type light inside and outside wall board

Abstract

The invention relates to an HP-CLC energy-saving embedded type light inside and outside wall board and a manufacturing method of the wall board. The wall board is prepared from 30-60 parts by weight of inorganic gel material, 30-45 parts by weight of inorganic low-gel material, 15-30 parts by weight of inorganic heavy framework material, 0.3-0.4 part by weight of toughening fiber, 1-1.5 parts by weight of high-performance activating agent, 0.1-0.3 part of macromolecule initiating agent and 40-50 parts by weight of water. The physical foaming principle is adopted, namely, hollow foams formed by high polymer material are stirred and homogenized into slurry of the inorganic gel material, and the gas is not generated by chemical foaming, so that the produced concrete product has the characteristics of being diversified in varieties, high in yield, stable in performances and durable in weather fastness, having the rate of finished products reaching up to 100%, etc. Furthermore, all the raw materials used in the product can be directly used without additionally processing and grinding, thus having no limitation; and therefore, the cost is saved, and the defects such as environmental pollution and the like can be overcome.

AI Technical Summary

Problems solved by technology

[0003] 1. Weight: The traditional lightweight partition wall is made of cemented slurry material with high water-cement ratio, and the dry volume density of the product is 1000-1300kg / m 3 In order to reduce the weight of the board itself, light-weight skeleton materials such as perlite, polystyrene waste particles, or composite sandwich polystyrene foam boards inside the board are added, and some circular holes are drawn out of the internal structure of the board to solve the weight of the board itself. Even this cannot solve the requirement of the weight of the plate itself. Generally, the weight of a plate with a length of 3000mm, a width of 600mm, and a thickness of 90mm is 120-150kg / piece, and the weight of a plate with a thickness of 120mm is 180-210kg / piece.

[0004] 2. Poor safety: The structure of traditional lightweight partition wall panels is hollowed-out circular holes or composite sandwich polystyrene foam panels. The thickness of the main panel protective layer is reduced, and the compressive strength, flexural strength, and impact resistance are all satisfactory. The strength design requirements of the building wall cannot be met. After the installed wall is cut by the embedded pipeline or decoration, the wall is easy to collapse, and the composite sandwich polystyrene foam board has a fire hazard.

[0005] 3. Poor durability: Most of the cementitious materials used in traditional lightweight partition boards are air-hardened cementitious materials, such as gypsum boards, magnesium oxide boards, and sulphoaluminate cement boards; The service life of the material is only 8-10 years. As time goes by, the strength of this type of wallboard will be greatly reduced, causing engineering quality problems such as wall cracking, pulverization, and water softening, especially in humid environments (such as kitchens, bathrooms) Serious quality problems will occur if the service life is at most 3-5 years

[0006] 4. Poor impact resistance and hanging load capacity: Since the traditional lightweight partition wall plate structure is hollow or composite sandwich material, the reinforcing ribs used are non-standard glass fiber mesh cloth, and the plate itself cannot bear the hanging air conditioner 1. The hanging strength requirements of heavy objects such as washbasins and picture frames are required. During installation and use, it is easy to cause plate breakage, low yield rate, and high defective rate.

[0007] 5. Wall cracking: The installation of traditional lightweight partition boards can easily cause cracks in the joint gap between the boards, mainly due to the large dry shrinkage value of the traditional lightweight partition boards themselves, and the mortise between the boards. The gap is small, and the tenon and groove are concave-convex trapezoidal, which is weak against self-shrinkage and wall stress changes, resulting in wall cracks

[0008] 6. Unstable products: The traditional light-weight partition wall panel products are not scientifically assembled, and the bulk density of the panels is uneven and the difference is large, resulting in uneven stress on the wall and cracking and displacement of the non-load-bearing wall between the load-bearing concrete beams and columns. other engineering safety hazards

[0009] 7. The use is limited: traditional lightweight partition wall panels can only be used for indoor non-load-bearing walls, not for wet walls in kitchens and bathrooms, let alone in exterior walls
