Preparing method for lightweight wall

Abstract

The invention discloses a preparing method for a lightweight wall. The preparing method comprises the steps that first, a housing structure main frame is made by utilizing I-steel or square steel, biomass-based polyurethane rigid foam materials are sprayed or poured in the interior space of the housing structure main frame, and biomass-based thermoplastic materials are adopted as thin lattice frames; second, auxiliary components are connected to the housing structure main frame, and a bottom layer inner wall plate and a bottom layer outer wall plate are connected to the auxiliary components; third, the biomass-based polyurethane rigid foam materials are poured or sprayed into cavities of the bottom layer inner wall plate and the bottom layer outer wall plate, so that a lower part wall is formed; fourth, a middle part inner wall plate and a middle part outer wall plate are installed, and the biomass-based polyurethane rigid foam materials are poured or sprayed into cavities of the middle part inner wall plate and the middle part outer wall plate, so that a partial wall is formed; and fifth, all partial walls are formed layer by layer according to the methods of the third step and the fourth step until the whole lightweight wall is formed. According to the preparing method for the lightweight wall, products are environmentally friendly, construction is convenient and rapid, the overall service life of housing is improved, energy saving, heat preservation and sound insulation properties are excellent, the overall strength is high, and the whole wall is small in weight.

Description

technical field [0001] The invention is applied in the building decoration industry and relates to a preparation method of a light wall. Background technique [0002] Stone mining brings more than 70% of the waste rocks. To deal with these waste rocks or occupy land for stacking or landfill, a large amount of valuable land is destroyed, and stone resources become a major public hazard that endangers the environment. These waste rocks are selected except for the production of a part of handicrafts, colored stone grits, and some light and heavy calcium carbonate produced by high-whiteness marble waste, and there is no effective and economically valuable method to utilize it. In the various mining areas that stretch for tens of miles, you can see mountains and ridges of rocks and slag of various colors everywhere, filling the ravines. The damaged environment is also prone to mudslides. [0003] With the development of modern industry and the surge of world population, energy c...

Problems solved by technology

[0006] Disadvantage 1: Resin-type artificial stone uses unsaturated polyester resin as a cementing agent. Since unsaturated polyester resin is liquid and other inorganic fillers are solid powder, it is not easy to mix evenly when mixing, and it is easy to generate heat during mixing, causing the resin to solidify in advance , resulting in uneven material of the finished sheet, easy to crack, warp and deform

[0007] Disadvantage 2: Resin-type artificial stone uses unsaturated polyester resin as the cementing agent, and the amount of resin used is too large, resulting in high cost of finished boards, not resistant to high temperatures, and is a combustible material
