Embodiment 1

[0045] Embodiment 1 Rock wool material preparation steps

[0046](1) Take 40 parts of basalt sand and 20 parts of dolomite sand, melt them at a high temperature above 1450℃, and centrifuge them into fibers at high speed with a four-axis centrifuge at a speed of 1500r / min. The centrifugation time depends on the total amount of basalt sand and dolomite sand. Adjust the quality, specifically 100kg / 30min, and cool to below 200°C after centrifugation for later use;

[0047] (2) Take 8 parts of binder, 5 parts of dustproof oil, and 5 parts of water repellent, spray them into the fibers after centrifugal cooling and stir them evenly;

[0048] (3) Take 10 parts of rigid foam polyurethane, 15 parts of polymer bonding mortar, 10 parts of thermal insulation mortar, and 8 parts of polymer plastering anti-cracking mortar, put them into a mixer and stir evenly for later use;

[0049] (4) Add the mortar mixture in step (3) to the fiber mixture in step (2) in batches and stir evenly, and put...

Embodiment 2

[0052] Embodiment 2 Adhesive preparation steps

[0053] (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;

[0054] (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;

[0055] (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.

[0056] The experimental results showed that when the mass ratio of red algae and corn starch was 1:3, the viscosity was the largest.

Embodiment 3

[0057] Example 3 Preparation steps of polymer bonded mortar

[0058] (1) Take 0.028 parts of disperse latex powder and 0.005 part of methyl cellulose ether respectively, divide the disperse latex powder into 4 parts evenly, then stir 0.005 part of methyl cellulose ether with one part of disperse latex powder evenly, and then Stir well with the other three parts of dispersed latex powder for later use;

[0059] (2) Take 1 part of cement and 1.5 parts of medium sand and mix them evenly for later use;

[0060] (3) Evenly divide the mixture of cement and medium sand into 10 parts, and then pour one part into the mixer for stirring. During the stirring process, spray the mixture of dispersed latex powder and methyl cellulose ether into it, and make it mix with the mixer. The mixture of cement and medium sand is mixed evenly;

[0061] (4) Then add another 9 parts of the mixture of cement and medium sand to the mixer in turn, and the amount added each time should not exceed 1 / 5 of ...

Abstract

The invention discloses a novel rock wool material which comprises the following components in parts by mass: 20-45 parts of basalt sand, 20-45 parts of dolomite sand, 5-10 parts of an adhesive, 3-8 parts of dustproof oil, 5-12 parts of a water repellent, 8-12 parts of rigid foam polyurethane, 10-20 parts of polymer adhesive mortar, 8-15 parts of thermal insulation mortar and 4-12 parts of polymerplastering anti-crack mortar. According to the novel rock wool material disclosed by the invention, the rigid foam polyurethane and the rock wool are compounded together, and experiments show that the rock wool material added with the rigid foam polyurethane can 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 rock wool material, in particular to a novel rock wool material, which belongs to the application field of rock wool materials. Background technique [0002] Rock wool material is an inorganic fiber material made of basalt as the main raw material and processed by high-temperature melting. It was successfully tested in June 1981. Rock wool material is a new type of thermal insulation, flame-retardant, and sound-absorbing material. [0003] Rock wool material is an artificial inorganic fiber processed by high-temperature melting, which has the characteristics of light weight, small thermal conductivity, heat absorption and non-combustibility. [0004] Under the social environment of low energy and environmental protection, ultra-low energy consumption buildings have become a rookie in the construction industry. Ultra-low energy consumption buildings refer to adapting to climate characteristics and natural conditions, adopting ...
