Formula of wall heat-insulating material

Abstract

The invention relates to a wall material, in particular to a formula of a wall heat-insulating material. The formula of the wall heat-insulating material comprises the following materials: 10 to 30 percent of spherical closed cell vitrified hollow microsphere with bulk weight of 90kg / m3, 8 to 18 percent of spherical closed cell vitrified hollow microsphere with bulk weight of 130kg / m3, 15 to 35 percent of ground calcium carbonate, 30 to 50 percent of 42.5R cement, 0.5 to 3 percent of wood fiber and 0.5 to 3 percent of dispersible latex powder. During the natural maintenance of the wall heat-insulating material adopting the formula, the wall heat-insulating material overcomes the defect that the common wall heat-insulating material cannot be maintained independently, and ensures that the water absorption and discharge automatically reach certain balance, thereby solving the problems of cracking, hollow joint and dropping-off after the construction; and complicated processes, such as a process of using fiberglass mesh and the like, are not needed so as to greatly reduce the using cost.

Description

technical field [0001] The present invention relates to wall materials. Especially suitable for the formulation of wall insulation materials. technical background [0002] At present, building energy-saving materials mainly use rubber powder and cement as coagulation materials. The aggregates are mainly organic materials such as polystyrene particles or traditional inorganic materials. The disadvantages are: not resistant to aging, large deformation coefficient, poor stability, safe and stable Poor performance, poor eco-environmental protection, difficult construction, high cost, poisonous and harmful gas will be produced. When applied to energy-saving projects, serious problems such as shedding, hollowing, and cracking often occur, and the service life is only about three years. At present, the wall insulation materials that appear on the market will seriously absorb or lose water due to seasonal climate changes after construction. This leads to problems such as cracking,...

[0002] At present, building energy-saving materials mainly use rubber powder and cement as coagulation materials. The aggregates are mainly organic materials such as polystyrene particles or traditional inorganic materials. The disadvantages are: not resistant to aging, large deformation coefficient, poor stability, safe and stable Poor performance, poor eco-environmental protection, difficult construction, high cost, poisonous and harmful gas will be produced. When applied to energy-saving projects, serious problems such as shedding, hollowing, and cracking often occur, and the service life is only about three years.

This not only makes the construction process too complicated, but also increases the cost
