Problems solved by technology

If glue and rivets are used to fasten EPX and XPE polystyrene insulation boards to the wall, it is easy to cause deep water phenomenon and damage to the wall of the building.
The polystyrene particles in the rubber powder polystyrene particle insulation material are organic materials, light in weight and have a certain degree of elasticity, it is difficult to make the rubber powder and polystyrene particles evenly distributed, resulting in poor affinity between polystyrene particles and cement, and when the temperature reaches At 30 degrees Celsius, the polystyrene particles will soften, loosen, hollow out, and fall off, so that the rubber powder polystyrene particle insulation material can only keep warm but has no heat insulation effect. When the temperature reaches above 80 degrees Celsius, the rubber powder particles will release A large number of toxic and harmful volatile gases of benzene bring serious pollution to the environment and serious harm to human health

Embodiment 1

[0030] 150kg of white cement, 360kg of vitrified microbeads with a particle size of 100 microns, 120kg of ceramic microbeads with a particle size of 100 microns, and 20kg of silica powder with a particle size of 0.1 microns were added to the mixer. Gravity mixer, specifically a conical mixer, start the machine, mix for 15 minutes, then add 180kg of aluminum silicate fibers with a diameter of 2.3 microns and a length of 2.5 mm into the mixer, and mix for 20 minutes. . The mixed product can be constructed after mixing with water. The weight ratio of the finished product and water is 1:1.5. After mixing, apply it to the wall or the surface of the substrate. The thickness of the paint on the wall is not less than 1.5 cm, and then the wall is evenly covered. You can also apply a second time or Apply three times until you reach the standard thickness required for construction. The thickness of the coating on the surface of the substrate is 1.5-2 mm, and then the temperature needs ...

Abstract

The invention relates a building material, in particular to inorganic active wall thermal insulation dry powder coating, which is formed by preparing the following raw materials, by weight percentage, 150-180 of aluminum silicate fiber, 150-180 of while cement, 5-20 of silicon oxide powder, 260-360 of vitrified small balls, 80-120 of ceramic small balls and 8-12 of redispersible rubber powder. The while cement, the vitrified small balls, the ceramic small balls and the silicon oxide powder are mixed evenly, then the redispersible rubber powder is added to be mixed evenly, and finally the aluminum silicate fiber is added and mixed evenly to obtain the coating. The inorganic active wall thermal insulation dry powder coating has good moisture-proof, waterproof, sound-proof, anti-flaming, antifouling and anticorrosion effects, and further has a strong thermal insulation function.

Description

technical field [0001] The invention relates to a building material, in particular to an inorganic active wall thermal insulation dry powder coating. Background technique [0002] Wall thermal insulation material is a new type of wall material developed in recent years, which can save a lot of wall materials, improve wall thermal insulation performance, save resources and reduce environmental pollution. At present, there are mainly two kinds of thermal insulation building materials used for building walls at home and abroad, one is EPX and XPE polystyrene thermal insulation board; the other is rubber powder polystyrene particle thermal insulation material. In foreign countries, the EPX and XPE polystyrene insulation boards are integrated with other materials into one plate structure, which is integrally fastened with glue and rivets and installed on the building wall. In my country, the EPX and XPE polystyrene insulation boards are directly attached to the building walls wi...
