Embodiment Construction

[0014] 1. Preparation of foamed phenolic particles:

[0015] Add the foamed phenolic form material into a disc sawtooth granulator to make granules of 0.1 to 5 mm. As foamed phenolic particles.

[0016] 2. Preparation of cementing and stabilizing material: Add calcium stearate to polyvinyl formal solution containing 50% water, and the ratio of polyvinyl formal aqueous solution: calcium stearate is 1:1, as a cementing and stabilizing material.

[0017] 3. Blank making: add 4 liters of water to the mixer, then add 100 ml of cementing stabilizer, 50 grams of short sisal fibers, 1 to 3 kg of foamed phenolic particles, and start the mixer at a stirring speed of 400 to 500 rpm. Stir well, then add 5 kg of No. 500 ordinary Portland cement, stir well for 1 minute, and finally add 500 ml of hydrogen peroxide solution with a content of 28%, stir quickly, and release it from the stirrer to the mold immediately when the volume expands In the process, after 5 days of hydration, the foame...

Abstract

The invention provides a method for preparing a foaming cement insulation board with foaming phenolic aldehyde particles. The method comprises the steps of preparation of the foaming phenolic aldehyde particles, preparation of adhesive stabilization material, preparation of blank, preparation of sizing agent, and enhancement processing. Compared with common foaming cement insulation boards, the foaming cement insulation board prepared by the method has the greatest advance of lowering the heat conductivity coefficient, increasing the toughness, lowering the volume weight, and reducing the using thickness; and the method is applicable to preparing insulation boards for wall bodies.

Description

technical field [0001] The invention proposes a thermal insulation material in the field of building materials, specifically a method for manufacturing a foamed cement thermal insulation board added with foamed phenolic particles. Background technique [0002] At present, with the country's emphasis on building energy conservation, various wall insulation materials have emerged as the times require. According to the needs of building fire protection, cement foam insulation board has also been applied. However, the disadvantages of the current cement foam insulation board are: large volume, poor toughness, high water absorption, high thermal conductivity, resulting in bulky volume, easy damage during handling, thick use, and large space occupation. The advantage of foam cement board is that it does not burn and can achieve fire prevention. [0003] Foamed phenolic board has also been applied, but its strength is low, and it is difficult to stick to the wall, but its thermal...
