Description
Technical Field
The invention belongs to the technical field of building materials, and particularly relates to a thermal insulation wall protective layer dry material, mortar and a wall.
Background
Heat insulation and preservation of buildings are important aspects of energy conservation, improvement of living environment and use functions. The proportion of building energy consumption in the whole human energy consumption is generally 30-40%, and most of the energy consumption is energy consumption of heating and air conditioning, so the building energy saving significance is great.
With the application of the external wall thermal insulation technology in practical engineering, the problems of external wall thermal insulation are gradually exposed. The existing external wall insulation board has the characteristics of gradually improving the durability, attractiveness and the like while paying attention to the insulation effect. For example, due to the influence of solar radiation, rain erosion, cold and hot temperature alternation and other factors, the surface layer of the finishing layer has the phenomena of surface layer fading, coating peeling, protective layer cracking, rain infiltration, partial or whole peeling of the external thermal insulation system of the external wall, and the like, thereby affecting the aesthetic property and the system durability. Even accidents caused by falling of the external heat insulation can lead to the inexistence of accidents of casualties.
The protective layer is used as a transition layer between the heat-insulating layer and the decorative layer, and the problems of cracking, hollowing, falling and the like of the heat insulation of the outer wall are mainly caused by the factors that the compactness of the material of the protective layer is low, the hydrophobicity is poor, the linear shrinkage coefficient, the wet-heat expansion coefficient and other performance differences of materials of all layers in the direction vertical to the heat-insulating material are large, the deformation of the heat-insulating layer and the decorative layer are different and the like under the influence of external factors, and finally the protective decorative layer of the heat-insulating system is far from the designed service life.
Therefore, in order to solve the above technical problems, the protective layer is required to have high flexibility so as to prevent the protective layer and the decorative layer from cracking; in order to prevent erosion of buildings by rain water and the like, the protective layer is also required to have high hydrophobicity and low water absorption.
Disclosure of Invention
Therefore, the technical problem to be solved by the invention is to overcome the defects of poor flexibility, insufficient hydrophobicity, high water absorption rate and the like of the protective layer of the heat-insulating wall in the prior art, so that dry materials, mortar and the wall of the protective layer of the heat-insulating wall are provided.
Therefore, the invention provides the following technical scheme:
the invention provides a thermal insulation wall protective layer dry material which comprises the following components in parts by weight,
150 portions and 350 portions of cement;
500 portions and 750 portions of sand;
50-200 parts of mineral filler;
1-60 parts of high molecular polymer;
3.1-10 parts of an additive;
0.1-1 part of sodium benzenesulfonate
Wherein the high molecular polymer is a mixture of redispersible latex powder and polyvinyl alcohol.
Optionally, the high molecular polymer comprises 15-50 parts of redispersible latex powder and 1-10 parts of polyvinyl alcohol.
Optionally, the particle size of the sand is not more than 480 μm;

Optionally, the mineral filler is at least one of fly ash, heavy calcium carbonate, talcum powder, light calcium carbonate and gypsum;
optionally, the specific surface area of the mineral filler is 2500-40000cm2/g。
Optionally, the additive is at least one of hydroxyethyl cellulose ether, starch ether, a water repellent, a water reducing agent, silicate and fluosilicate.
Optionally, the additive comprises 2-4 parts of hydroxyethyl cellulose ether, 0.1-0.5 part of starch ether, 1-5 parts of water repellent, 0.1-2 parts of water reducer and 0.1-2 parts of silicate and/or fluorosilicate.
The concrete selection of the cement and the admixture of the invention has no special requirements, such as:
optionally, the cement is at least one of 42.5 cement, 72.5 cement, high aluminate cement and white cement;
the water repellent is an organic silicon water repellent; optionally powder-A, powder-D, N710 or P750;
the water reducing agent is a polycarboxylic acid water reducing agent, and FOX-C900 and 5731F can be selected;
the silicate is nano lithium silicate, nano sodium silicate or nano potassium silicate;
the fluosilicate is nano sodium fluosilicate or nano potassium fluosilicate.
The invention also provides thermal insulation wall protective layer mortar which comprises the thermal insulation wall protective layer dry material.
Optionally, the mass ratio of the water to the dry material of the protective layer of the heat-insulating wall body is 0.1-0.2.
The invention also provides a heat-insulating wall, which comprises the protective layer mortar of the heat-insulating wall.
The technical scheme of the invention has the following advantages:
the heat-insulating wall protective layer dry material provided by the invention comprises the following components, by weight, 150 parts of cement and 350 parts of cement; 500 portions and 750 portions of sand; 50-200 parts of mineral filler; 1-60 parts of high molecular polymer; 3.1-10 parts of an additive; wherein the high molecular polymer is a mixture of redispersible latex powder and polyvinyl alcohol. According to the invention, through the matching among the components and the adjustment of the dosage, the strength can be ensured and the flexibility of the material can be improved. Specifically, the higher the cement mixing amount is, the higher the strength is, and the higher the rigidity is; therefore, in order to obtain a high-flexibility material, the dosage of cement is controlled, and meanwhile, the cement is matched with other components with specific compositions, particularly a high molecular polymer with specific compositions, so that the flexibility of the material can be improved while the strength of the material is ensured, wherein the matching of the high molecular polymer and sodium benzenesulfonate can ensure the flexibility and the viscosity of the key components of mortar.
The dry material for the protective layer of the heat-insulating wall body, provided by the invention, has the advantages that the surface is smooth and fine after the protective layer is constructed, and the compactness is good due to the limitation of the sand particle size.
