Embodiment 1

[0047] Embodiment 1 Rock wool material preparation steps

[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 form fibers at high speed, and cool it to below 200°C for later use;

[0049] (2) Take 8 parts of binder, 5 parts of dustproof oil, and 10 parts of water repellent, spray them into the fibers after centrifugal cooling and stir them evenly;

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

[0051] (4) Add the mortar mixture in step (3) to the fiber mixture in step (2) in batches and stir evenly, and put it into the mold after mixing;

[0052] (5) The formed rough plate is dried in an oven at 220°C for more than 4 ho...

Embodiment 2

[0054] Embodiment 2 Adhesive preparation steps

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

[0056] (2) Take 60 parts of corn starch, add an equal amount of 35% sodium hydroxide solution and 30% hydrogen peroxide solution to it, heat to 65°C, and react for 1.5 hours. After the reaction, the cassava flour is prepared with water to make the pH neutral;

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

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

Abstract

The invention discloses an inorganic thermal insulation material for a wall. The inorganic thermal insulation material comprises the following components in parts by mass: 35-60 parts of basalt sand,5-8 parts of aluminum hydroxide, 8-12 parts of nanoparticles, 5-10 parts of a binder, 3-8 parts of dustproof oil, 5-10 parts of a water repellent, 3-15 parts of expanded perlite, 5-12 parts of rigid foam polyurethane, 4-8 parts of polymer bonding mortar, 3-10 parts of thermal insulation mortar, 4-12 parts of polymer plastering anti-crack mortar and 10-15 parts of water. According to the inorganicthermal insulation material disclosed by the invention, the nanoparticles are added into the raw materials, so the loading capacity and the surface area of a traditional inorganic thermal insulation material for a wall are increased; and besides, the rigid foam polyurethane and rock wool are compounded together, and experiments show that a rock wool material added with the rigid foam polyurethanecan greatly reduce the K value of the heat transfer coefficient of an outer wall, and meets the technical indexes of ultralow-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, and rich raw materials. However, due to their light weight, inorganic thermal insulation materials have a small lifting capacity, and because most of the wall glue used in inorganic thermal insulation materials is 107 glue or 801 Construction glue, because it contains harmful chem...
