Problems solved by technology

[0005] (1) While meeting the strength requirements, the self-weight is relatively large, the consumables are more, and the project cost is relatively high;
[0006] (2) Corrosion resistance and fire resistance are poor, for example: the wall panels are easy to fall off after a long time, not beautiful, and it is difficult to decorate the prefabricated wall panels with the internal wall insulation method;
[0007] (3) The autoclaved aerated concrete products with a thickness of 240mm~260mm in the self-insulation system have too high moisture content, and the thermal resistance value is far lower than expected, which makes it difficult to meet the requirements of energy-saving standards

Embodiment 1

[0025] Embodiment 1: A kind of manufacture method of self-insulating non-load-bearing wallboard, its steps are as follows:

[0026] 1) Clean the inner wall of the mold box according to the specifications required by the order, and spray the release agent on the inner wall of the clean mold box 4 hours in advance. After the release agent is completely dry, fix the fiber mesh cloth or steel wire mesh on the The inner walls on both sides of the mold box can be poured;

[0027] 2) Stirring of ingredients: start the mixer, add water 13.5%, admixture 0.9%, foam stabilizer 2.7%, polypropylene fiber 1.3%, fly ash 17%, heavy calcium carbonate powder 10% and cement 52% by weight. %, make it fully stirred evenly, and then add foaming agent 2.6%. During the stirring process, pay attention to observe the consistency and leveling of the slurry until the color of the slurry is consistent, and then make foamed concrete; where: the The cement is 425# Portland cement; the fly ash is grade 2, w...

Embodiment 2

[0035] Embodiment 2: step 2) batching stirring: start the mixer, add water 16.1%, admixture 1.1%, foam stabilizer 1.8%, fiber 2.6%, fly ash 8.9%, ground calcium carbonate powder 10% successively by weight And cement 57.6%, make it fully stirred evenly, then add foaming agent 1.9%. If the mold box in step 3) in Example 1 is poured, it is necessary to add a steel wire mesh with a diameter of 3mm and an aperture of 4×4mm, and a sword drawing machine can be used to draw back and forth twice to ensure the uniformity of the pores on the surface of the board.

[0036] Others are the same as in Example 1.

Embodiment 3

[0037] Embodiment 3: the present invention step 2) ingredients stirring: start the mixer, add water 17.3%, admixture 1.0%, foam stabilizer 1.8%, fiber 2.9%, fly ash 12.6%, heavy calcium carbonate powder in order by weight 11.7% and cement 51%, make it fully stirred evenly, and then add foaming agent 1.7%. If step 3) in Example 1 is completed after the mold box is poured, it is necessary to add a fiber mesh cloth with a pore size of 2.52. Fix it and use a vibrator to vibrate at a frequency of 250-300 times per minute.

[0038] Others are the same as in Example 1.

Abstract

The invention discloses a manufacturing method of a self-heat-preservation non-bearing wallboard. The manufacturing method comprises the following steps of ingredient stirring, mold box pouring, upper forming manufacturing, temperature control precuring, demolding and board discharging, and acceptance and warehousing. The manufacturing method solves the problem of instability of traditional foam, reduces the overall construction cost, and has obvious economic benefits; and a wall body is not easy to fall off, the adhesive force of the wall to decorative materials is improved, an inner wall can be decorated, the structural space self-heat-preservation performance is high, the weight is light, manufacturing is easy, materials and energy are saved, and the engineering cost can be greatly reduced.

Description

technical field [0001] The invention relates to an enclosure wall component of building construction, in particular to a self-insulating non-load-bearing wall panel and a manufacturing method thereof. Background technique [0002] With the continuous improvement of energy-saving standards and energy efficiency in the construction industry, and the gradual implementation of green building industrialization, especially the building energy-saving work in cold northern regions is facing increasing pressure. The thickness of the wall insulation layer using self-insulation technology is large. As the range increases, the heat insulation, sound insulation, safety and durability of the interior wall insulation system have become the main technical issues. In addition, the moisture content of 240mm~260mm thick autoclaved aerated concrete block products in a large number of self-insulation technology systems on the market is too high, and the thermal resistance value is far lower than...
