Description
Technical Field
The invention belongs to the field of building base materials, and particularly relates to an inner wall multifunctional base material taking expanded microspheres as thermal insulation aggregate and a preparation method thereof.
Background
With the improvement of living standard of people, more and more people can select inner wall heat preservation while having outer wall heat preservation, but in view of the prior art at present, common inner wall heat preservation materials have irreconcilable contradictions on a plurality of important performance parameters. The common interior wall heat preservation at present has: EPS/XPS insulation boards, polyurethane foam, interior wall insulation coatings, vitrified micro bubbles insulation materials and the like. These thermal insulation materials have various characteristics, but also have various problems.
Several common insulating layers have obvious disadvantages:
EPS/XPS insulation board: the advantages are excellent heat insulating property, water resistance and impact resistance. The defects of low strength and poor bearing capacity; the flame retardant property is poor, and a large amount of toxic gas can be released during combustion; in construction, the requirement on the flatness of the wall is high; the construction process is complicated, needs to be bonded by a binder, reinforced by grid cloth, added with an anchoring part and the like; the material is easy to age and shrink, so that splicing cracks and large-area falling are often caused.
2. Polyurethane foam: in the aspect of application, the polyurethane foam is greatly influenced by seasons and temperature, and the foaming rate of the polyurethane foam is reduced at the temperature below 10 ℃; and the spray forming speed is high, the smooth spray effect is difficult to make, and the surface is uneven.
3. Inner wall heat-insulating coating: the heat preservation and insulation performance is poor, and condensation and dewing phenomena are easy to occur; cracks are easily generated.
The patent with application number 201110411371.5 discloses an elastic fluorocarbon heat-insulating coating, a preparation method and a use method thereof, which adopt hollow glass beads and hollow high-molecular polymers, but adopt fluororesin organic matters as base materials and account for the maximum component proportion, namely: 55-65. The organic base material can release a large amount of aromatic compounds which are toxic and harmful to human bodies in the actual decoration and use process, the increasing requirements of the market on the environmental protection performance are difficult to meet, the organic base material can be used after long-time waiting after being used by a building, and the decoration period and the time cost are greatly increased; in the aspect of fire resistance, although fluorocarbon paint is safe and nontoxic below the decomposition temperature, once a fire breaks out, various toxic harmful gases such as phosgene, fluoroolefin and the like can be released; and the heat-insulating coating is high in cost due to the fact that a large amount of organic matter components are applied, and cannot be applied in many scenes needing to control cost.
The patent with application number 201810165769 discloses a heat-insulating and sound-insulating putty paste for interior walls and a preparation method thereof, wherein nano-scale hollow microbeads and micron-scale hollow expandable elastic microbeads are adopted, rock wool is adopted, and the components of the putty paste contain synthetic resin emulsion. The technical scheme has obvious defects, firstly, the materials are expensive, and practical production and application are difficult to realize; as mentioned in the background section, the rock wool is easy to absorb excessive moisture and is easy to accumulate for a long time to cause the specific gravity of the heat insulation layer to increase, and accidents caused by falling of the rock wool are common, and considering that synthetic resin emulsion and bentonite slurry are also used as cementing materials in the formula, the two materials are hydrophilic materials, so that the water resistance of the finished product is poor, the bonding strength is low after water resistance is achieved, and the danger of use is further increased; in addition, the putty paste provided by the prior art is difficult to be constructed thickly at one time in construction, and multiple constructions are needed to increase the construction cost and time cost if the heat preservation effect is achieved; and the adopted synthetic resin emulsion can also cause formaldehyde release, and cannot meet the current requirements on environmental protection performance.
Gypsum is used as an inorganic gelling agent, the natural excellent flame retardant property and environmental protection property are the natural advantages of the gypsum as a base material, but as for the gypsum-based products in the prior art, according to the feedback of the market on the products and the understanding of the characteristics of gypsum, the conventional gypsum-based products are mainly leveled, cannot achieve the effective heat preservation, heat insulation and sound insulation effects, and the specific gravity is generally 1200-1400kg/m3And not a light product. In addition, the conventional gypsum-based product has poor water resistance, is easy to loosen and bubble when meeting water, and is easy to fall off and pulverize when meeting water and tide for a long time, and is easy to mildew. The initial adhesion is strong, and the product strength is instantly improved, but the adhesion is reduced with the passage of time, and the strength is also reduced.
The heat-insulating building base materials in the prior art have defects, and have irreconcilable contradictions in the aspects of cost, use safety, sound insulation performance, water resistance, fire resistance, heat insulation performance, coating rate, strength and specific gravity.
In view of this, it is a technical problem to be solved by those skilled in the art to design a multifunctional substrate for interior walls, which has a high coating rate, and has the characteristics of good heat preservation and insulation effects, high shear resistance, light weight, leveling, water resistance, fire resistance, sound insulation and environmental protection.

The newly plastered cement wall is subjected to full maintenance and then scrapped on the multifunctional base material of the inner wall; before construction of old wall, paint, oil stain, empty shell and floating ash should be removed, alkali-resistant treatment is done, and construction can be carried out when the water content of wall body is less than 10% and pH is less than 10. The wall with serious efflorescence and the wall with open water can not be directly used and can be used only after being qualified.
Construction: the construction can be carried out by steel batch cutters and scrapers, and also can be carried out by mechanical spraying. The product is required to be mixed with clear water uniformly for use, and 5.0-5.5 parts of water (the consistency is suitable for construction) is added into 10 parts of multifunctional inner wall base material powder according to the mass ratio.
