A gangue foam concrete building block for realizing self heat insulation of walls relates to a self-heat-insulation foam concrete building block of light walls and consists of a high-strength gangue foam concrete shell and an ultra-low-density foam concrete core. Gangue solid wastes are utilized as main raw materials, are used for preparing the gangue foam concrete building block for realizing self heat insulation of walls, and are turned into wealth, cost of products is reduced, natural resources are saved, and the gangue foam concrete building block is favorable for environmental protection. In addition, the gangue foam concrete building block further has the advantages that strength is high, heat conduction coefficient is low, heat insulation is good, the gangue foam concrete building block is directly plastered after being built, heat insulation treatment on the inner side or outer side of a wall is not required, construction speed is greatly increased, construction completion time is shorted, and the like. Accordingly, the gangue foam concrete building block can be widely used for building single heat-insulation walls (with a self heat insulation effect) of external walls, internal and external partition walls of frame structures, rear plate walls of large wall cabinets, and fireproof, sound-insulation and heat-insulation layers of internal walls.

The invention relates to light-weight and energy-saving plastering mortar, which is prepared by mixing the following components in part by weight: 30 to 40 parts of ordinary Portland cement, 2 to 4 parts of hydrated lime, 10 to 20 parts of light aggregate, 40 to 50 parts of heavy aggregate and 1.0 part of compound aid, wherein the light aggregate is an inorganic vitrified hollow microporous material of which the fineness is below 100 meshes; and the heavy aggregate is aeolian sand. During construction, the light-weight and energy-saving plastering mortar is diluted by water added in an amountwhich is 30 to 50 percent based on the weight of the light-weight and energy-saving plastering mortar, and is stirred and mixed mechanically or manually and uniformly until the plastering mortar has the suitable viscosity, and then mechanical spraying or manual construction Is performed. According to the concept of light weight and eco-environmental protection, the light-weight and energy-saving plastering mortar is made light by adopting the inorganic vitrified hollow microporous material, and is matched with the primary elastic modulus of a light-weight wall body to reduce coefficients of heat conductivity and reduce the thermal bridge effect, so the light-weight and energy-saving plastering mortar prevents hollowing, cracking and shedding, insulates heat and reduces noise, and is favorable for mechanized construction. The aeolian sand is used as aggregates, so the plastering mortar has excellent grading distribution and has the prominent three-dimensional texture; and the special compound aid is adopted to improve the peaceability of the mortar to achieve the excellent construction effect.

The invention discloses inner wall decoration mortar, which is mixed by the following components in part by weight: 8 to 15 parts of common silicate cement, 3 to 4 parts of slaked lime, 3 to 5 parts of light aggregate, 4 to 6 parts of negative ion aid, 70 to 80 parts of heavyweight aggregate (wind-carried sand) and 1.0 part of composite aid, wherein the light aggregate is an inorganic vitrified hollow cellular material with thickness of lower than 100 meshes. The decoration mortar is environment-friendly, natural, long-acting and stable, has the advantages of prominent three-dimensional texture, good decoration effect, good grain composition, small heat conducting coefficient and reduced heat bridge effect, effectively prevents the inner wall from cracking, hollowing and dropping, and is favorable for mechanized construction; and the decoration mortar can eliminate indoor unclean and harmful substances, purify the air, continuously keep the indoor air fresh and promote human health bycontinuously generating negative ions. The inner wall decoration mortar is diluted by water in an amount which is 30 to 50 percent of the weight of the mortar and then is mechanically coated or manually constructed.

The invention provides a vacuum thermal insulation plate, a cold keeping box and a production method thereof. The vacuum thermal insulation plate comprises a core plate and a film bag for sealing and coating the core plate and vacuumized, and is characterized in that folding plates are arranged on the same planes of the four sides of the core plate in the film bag; and when all the folding plates are overturned to the same side corresponding to the core plate by 90 degrees, the folding plates and the core plate form a box body with one opened side. The box body can be folded by using one vacuum thermal insulation plate, so that the box body molding steps are simplified; and one vacuum thermal insulation plate is adopted, so that both time and labors are saved in box body molding. As the final size of the box body can be accurately controlled only by accurately controlling the sizes of the core plate and the folding plates, the product size consistency is guaranteed in large-batch production. A foaming material and the vacuum thermal insulation plate are molded as a whole, so that the shape size is further precise, the wear resistance and the impact resistance of the vacuum thermal insulation plate can be greatly improved, and the vacuum thermal insulation plate is not easy to damage.

The invention relates to a prefabricated concrete sandwich thermal insulation exterior wall panel, which belongs to the technical field of thermal insulation exterior wall panels, and includes an inner leaf concrete wall panel, an airgel fiber felt, an outer leaf concrete wall panel, and a plurality of connectors. The connection core made of carbon fiber material, the connection sleeve made of glass fiber reinforced plastic material, the connection sleeve is sleeved on the outer peripheral surface of the connection core and has an interference fit with it, and one end of the connection core along its length direction is provided with a The feed hole, the connecting core is set on the outer peripheral surface of the connecting sleeve and has multiple discharge holes along its circumferential direction. The discharge hole and the feed hole are connected. The side wall of the connecting sleeve is provided with a A perforation that connects the material holes. The prefabricated concrete sandwich thermal insulation exterior wall panel adopts airgel fiber felt, which has good fireproof performance, and utilizes the mutual cooperation between the connecting core body and the connecting sleeve to reduce the occurrence of "heat" at the joints of the thermal insulation exterior wall panel. The bridge effect improves the thermal insulation effect of the thermal insulation exterior wall panels.
