Example Embodiment

[0023] The present invention will be further described in detail below in conjunction with embodiments:

[0024] Prepare 1000 kg of calcium silicate board for the new thermal insulation firewall body:

[0025] The first step: prepare raw materials according to the following components and their mass percentages: 350 kg of quartz sand, 150 kg of Portland cement, 250 kg of slaked lime, 50 kg of mica, 130 kg of vermiculite, and 70 kg of wood pulp fiber;

[0026] Step 2: Paper shredding: Put the pieces of paper into the paper shredder with water, set the shredding time according to different types of paper, and control the shredding density within 10%, and then pump the shredded pulp into the paper storage tank , Start the refiner, the current is controlled at 150-170A, and the pulp buckling degree is controlled at 30-35SR. , The temperature and weight are controlled at 4-5g, and finally the crushed pulp is stored in the pulp pool for future use;

[0027] The third step: pulping: accordi...

Abstract

The invention discloses a novel thermal insulation fireproof wall calcium silicate board and a preparation method thereof. The novel thermal insulation fireproof wall calcium silicate board comprises the following components in percentage by mass: 30-40% of quartz sand, 5-15% of portland cement, 25-40% of slaked lime, 3-5% of mica, 8-13% of vermiculite and 7-8% of wood pulp fiber. The preparation method comprises the following steps of: preparing raw materials by using all the components in percentage by mass; shredding paper; pulping; discharging pulp; forming; carrying out three-working-position operation; demoulding; autoclave curing; drying; and sanding to obtain the novel thermal insulation fireproof wall calcium silicate board. The novel thermal insulation fireproof wall calcium silicate board remains the favorable universality of a calcium silicate board and has an extremely low coefficient of heat conduction. The coefficient of heat conduction of the novel thermal insulation fireproof wall calcium silicate board provided by the invention is (31+273)K, 0.154W/mk; (100.5+273)K, 0.164W/mk.

Description

technical field [0001] The invention relates to a board, in particular to a novel calcium silicate board for heat-insulating and heat-insulating fire walls, and also relates to a preparation method thereof. Background technique [0002] Thermal insulation materials and products are an important factor affecting building energy conservation. The development and application of building thermal insulation materials have attracted more and more attention from all over the world. After the 1970s, foreign countries generally paid attention to the production of thermal insulation materials and their application in construction, and strived to greatly reduce energy consumption, thereby reducing environmental pollution and greenhouse effect. The thermal insulation material industry in foreign countries has a long history, most of which are thermal insulation materials for building energy conservation, and new thermal insulation materials are also emerging continuously. The energy lo...
