Embodiment 1

[0047] Example 1 Preparation steps of rock wool material

[0048] (1) Take 60 parts of basalt sand, melt it at a high temperature above 1450 °C, and then use a four-axis centrifuge to centrifuge it into fibers at a high speed, and cool it to below 200 °C for use;

[0049] (2) Take 8 parts of binder, 5 parts of dust-proof oil, and 10 parts of water repellent, spray into the fiber after centrifugal cooling and stir evenly;

[0050] (3) Take 8 parts of aluminum hydroxide, 10 parts of nanoparticles, 15 parts of expanded perlite, 7.5 parts of rigid foam polyurethane, 4 parts of polymer bonding mortar, 5 parts of thermal insulation mortar, 7 parts of polymer plastering and anti-cracking mortar, water 10 servings, put in a blender and mix well for later use;

[0051] (4) adding the mortar mixture in the step (3) into the fiber mixture in the step (2) in batches and stirring it evenly, and putting it into the mold after the mixing is completed;

[0052] (5) The formed blank board is...

Embodiment 2

[0054] Example 2 The preparation steps of the binder

[0055] (1) Take 20 parts of red algae, add double 4% sodium hydroxide solution to it and soak for 2.5 hours, and heat to 100 ° C, stir while heating, and adjust pH with water to be neutral after 2.5 hours;

[0056] (2) get 60 parts of cornstarch, add 35% sodium hydroxide solution and 30% hydrogen peroxide solution of equal amount therein, be heated to 65 ℃, react 1.5 hours, the tapioca flour after the reaction modulates ph with water to be neutral;

[0057] (3) Put the treated red algae slurry and corn starch into a mixer, add 30-35 parts of water, heat while stirring, heat to 65°C and keep for 3 hours, adjust the pH to 6.8±0.1 with acetic acid , filtered to obtain a clear glue.

[0058] The experimental results show that when the mass ratio of red algae and corn starch is 1:3, the viscosity is the largest.

Embodiment 3

[0059] Example 3 Preparation steps of polymer bonded mortar

[0060] (1) Take 0.028 part of disperse latex powder and 0.005 part of methyl cellulose ether respectively, divide the disperse latex powder into 4 parts evenly, and then mix 0.005 part of methyl cellulose ether and one part of the disperse latex powder evenly, and then in turn Mix it with the other three parts of disperse latex powder evenly for later use;

[0061] (2) Take 1 part of cement and 1.5 parts of medium sand and mix them evenly for later use;

[0062] (3) The mixture of cement and medium sand is evenly divided into 10 parts, and then one part is poured into the mixer for stirring. During the stirring process, the mixture of disperse latex powder and methyl cellulose ether is sprayed into it to make it mix with the mixer. The mixture of cement and medium sand is evenly mixed;

[0063] (4) Add another 9 parts of the mixture of cement and medium sand into the mixer in turn, and the amount added each time s...

Abstract

The invention discloses an inorganic wall body thermal insulation material, comprising the following parts by mass, including the following parts by mass: 35-60 parts of basalt sand, 5-8 parts of aluminum hydroxide, 8-12 parts of nanoparticles, adhesive 5-10 parts of anti-dust agent, 3-8 parts of dust-proof oil, 5-10 parts of water repellent, 3-15 parts of expanded perlite, 5-12 parts of rigid foam polyurethane, 4-8 parts of polymer-bonded mortar, thermal insulation mortar 3-10 parts, polymer plastering anti-cracking mortar 4-12 parts, water 10-15 parts. The invention discloses an inorganic wall thermal insulation material. Nano particles are added to the raw material, which increases the load and surface area of ​​the traditional inorganic wall thermal insulation material. In addition, the rigid foam polyurethane and rock wool are compounded together. , Experiments have shown that adding rigid foam polyurethane rock wool material can greatly reduce the K value of the heat transfer coefficient of the exterior wall, which is in line with the technical indicators of ultra-low energy consumption buildings.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to an inorganic wall thermal insulation material, which belongs to the application field of thermal insulation materials. Background technique [0002] Wall thermal insulation materials can improve the thermal insulation performance of the wall. They are divided into organic thermal insulation materials, inorganic thermal insulation materials and composite thermal insulation materials. Inorganic thermal insulation materials generally use perlite cement board, rock wool board, foam cement board, etc. , Inorganic thermal insulation materials have the advantages of light weight, good thermal insulation effect, rich raw materials, etc., but inorganic thermal insulation materials are due to their light weight, resulting in low load-bearing capacity, and because the wall glue used in inorganic thermal insulation materials is mostly 107 glue or 801 glue Construction glue, because it contain...
