preparation example Construction

[0062] The preparation method of self-variable temperature building energy-saving composite material is as follows:

[0063] The first step: First, when selecting phase change materials, when selecting phase change solid raw materials, organic phase change materials with a phase change temperature of 18-58°C and a phase change enthalpy above 110kj / kg should be selected. The phase change material is in the production process. The medium should always be kept in a solid state, and then prepared according to the following weight ratio raw materials: phase change solid raw material 18kg, wood fiber 1kg, 42.5 grade high alumina cement 13kg, drinking water 1kg, polymer emulsion (acrylic emulsion) 3kg, First crush the phase change solid material and mix it with the above formula materials uniformly, and then make phase change pellets with φ3mm-8mm on the granulator;

[0064] The second step: mix the following raw materials by weight: 32.5 grade silicon cement 10kg, plasticizer 0.2-1kg, p...

Abstract

The invention relates to an automatic temperature varying building energy-saving composite material and a preparation method thereof. The preparation method comprises the following steps: blending crushed phase-change solid raw wood, wood fibers, 42.5-level high-aluminum cement, drinkable clear water and polymer emulsion (polyacrylate emulsion) to form phase-change granular balls with phi3 to phi8 mm; evenly mixing gelled material, plasticizing agent, polymer emulsion (polyacrylate emulsion), film forming agent, thin quartz sand and dispersant to form high molecular polymer clad grout, wrapping the phase-change granular balls by the grout, and after each phase-change granular ball is fully and evenly wrapped, dispersing the phase-change granular balls, curing membranes to form clad phase-change granular balls, and screening the phase-change granular balls for standby; and finally, evenly mixing the gelled material, fiber material, lime hydrate, re-dispersible latex powder, methylcellulose ether, thermal insulation lightweight material, heavy calcium powder and the clad phase-change granular balls which are added according to a mixture ratio to form powder of a phase-change composite finished product. The composite material has the advantages of heat insulation, energy conservation and environmental protection, fire prevention and flame retardance, noise reduction and sound isolation, crack resistance and moisture protection, simple process, convenience for production and construction, and low cost.

Description

Technical field [0001] The invention relates to a building energy-saving composite material and a preparation method thereof, in particular to a self-changing temperature building energy-saving composite material with heat preservation and heat insulation, energy saving, consumption reduction, environmental protection and simple production and construction, and a preparation method thereof. Background technique [0002] As we all know, with the rapid development of national economic construction and the increasing improvement of people's quality of life, it is imperative to seek an energy-saving, high-efficiency, comfortable, and green technology development route in the construction field.
