Embodiment 1

[0011] The specific preparation process of the present embodiment is as follows:

[0012] Step 1: Weigh each component according to the following ratio: 98.99% of building gypsum powder, 0.5% of inorganic phase change material, 0.1% of regulator, 0.3% of water-retaining thickener, 0.01% of adhesive, and 0.1% of reinforcing agent; , the above percentages are percentages by weight;

[0013] Step 2: Add construction gypsum powder to the mixer, and at the same time add phase change materials and other additives to the mixer, mix and pack according to a certain weight to complete the product.

[0014] The above-mentioned inorganic phase change materials are nano-layered silicate, sulfonates and citric acid are selected as regulators, methyl cellulose and sodium carboxymethyl cellulose are selected as water-retaining thickeners, and rubber powder is selected as adhesive to enhance The agent uses borax and boric acid.

Embodiment 2

[0017] The specific preparation process of the present embodiment is as follows:

[0018] Step 1: Weigh each component according to the following ratio: 80.7% of building gypsum powder, 10% of organic phase change material, 8% of regulator, 1% of water-retaining thickener, 0.2% of adhesive, and 0.1% of reinforcing agent; , the above percentages are percentages by weight;

[0019] Step 2: Add construction gypsum powder to the mixer, and at the same time add phase change materials and other additives to the mixer, mix and pack according to a certain weight to complete the product.

[0020] The above-mentioned organic phase change materials are liquid paraffin, sulfonates and citric acid are selected as regulators, methylcellulose and cellulose ethers are selected as water-retaining thickeners, rubber powder is selected as adhesive, and borax and boric acid are selected as reinforcing agents. .

Embodiment 3

[0023] The specific preparation process of the present embodiment is as follows:

[0024] Step 1: Weigh each component according to the following proportions: 70.2% of construction gypsum powder, 25% of composite phase change material, 4% of regulator, 0.5% of water-retaining thickener, 0.2% of adhesive, and 0.1% of reinforcing agent; , the above percentages are percentages by weight;

[0025] Step 2: Add construction gypsum powder to the mixer, and at the same time add phase change materials and other additives to the mixer, mix and pack according to a certain weight to complete the product.

[0026] Above-mentioned composite phase-change material selects titanium dioxide and polyvinyl acetate, the two each account for 50% (percentage by weight), adjuster selects sulfonate and citric acid etc. for use, water retention thickener selects methyl cellulose, carboxymethyl Sodium cellulose and cellulose ethers, rubber powder as the adhesive, borax and boric acid as the reinforcing...

Abstract

The invention discloses a novel environment-friendly phase change plastering putty, which comprises the following components in percentage by weight: 0.1 to 8 percent of modifier, 0.5 to 25 percent of phase change material, 0.3 to 1 percent of water retention agent, 0.01 to 0.2 percent of bonding agent, 0.1 to 2 percent of intensifier, and the balance of construction gypsum. Because the phase change having the characteristics of energy storage is added, and the modifier, the intensifier and the like are also added, the novel environment-friendly phase change plastering putty has the characteristics of ensuring the basic performances of the plastering putty, simultaneously automatically adjusting the ambient temperature in the room and making an indoor air-conditioning system operate smoothly, and meeting the requirements of modern people on the high-quality living environment.

Description

technical field [0001] The invention relates to an environment-friendly phase-change plastering putty, in particular to a new type of environment-friendly phase-change plastering putty which can automatically adjust the temperature of the indoor environment and is suitable for the high-quality requirements of modern people for the living environment. Background technique [0002] The development of modern buildings to high-rise buildings requires the envelope structure to be made of lightweight materials. However, the heat capacity of ordinary lightweight materials is small, resulting in large fluctuations in indoor temperature. This not only makes the indoor thermal environment uncomfortable, but also increases the air-conditioning load, leading to an increase in building energy consumption. [0003] In recent years, the Chinese government has vigorously advocated the development and application of energy-saving materials, and the building materials industry, especially th...
