Problems solved by technology

It has the following disadvantages: First, the resin-type artificial stone is made of unsaturated polyester resin as a cement. Since the unsaturated polyester resin is liquid and other inorganic fillers are solid powder, it is not easy to mix evenly when mixing. It is easy to generate heat and cause the resin to solidify in advance, resulting in uneven material of the finished board, easy to crack, warp and deform
Second, resin-type artificial stone uses unsaturated polyester resin as a 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

preparation example Construction

[0029] Such as Figure 1 to Figure 3 As shown, the invention provides a kind of preparation method of lightweight wall, comprising:

[0030] Step 1, making boards: mixing stone waste, cement, sand, mica powder and thermosetting phenolic resin powder, wherein the mass ratios of each material in the raw materials are: stone waste 50-80%, cement 10- 20%, sand 1-20%, mica powder 1-20%, thermosetting phenolic resin powder 6-10%, the mixed material is evenly spread in the mold through the distribution system, and the mold and material are pressed by the cold pressing system. The layer is pre-pressed at room temperature, and then the mold is put into a multi-layer hot press to solidify and form, cooled and lowered, the mold is opened, matured, and post-treated to obtain a plate;

[0031] Step 2. Making biomass-based polyurethane rigid foam material: enzymatically hydrolyzing and fermenting the biomass raw material to obtain slag, the main component of which is lignin; drying and pul...

Abstract

The invention discloses a preparation method for a lightweight wall, wherein the preparation method includes the steps: mixing stone waste, cement, sand, a mica powder and a thermosetting phenolic resin powder, carrying out normal temperature pre-pressing of the mold and a material layer by a cold pressing system, then putting the mold into a multi-layer hot press, carrying out curing forming, cooling, opening the mold, aging, post-treating, and thus obtaining a plate material; liquifying a lignin particle raw material with polyethylene glycol 400 and glycerol into biopolyol under a conditionwith sulfuric acid as a catalyst, mixing the biopolyol and an auxiliary agent into a combined biopolyol, and then using the combined biopolyol for carrying out a reaction with isocyanate to form a biomass-based polyurethane hard foam material; and taking the plate material as an inner wall plate and an outer wall plate, mounting on a housing structure frame, spraying and pouring the biomass-basedpolyurethane hard foam material in a cavity between the inner wall plate and the outer wall plate, and thus preparing the lightweight wall. Original natural resources are not consumed directly, and the prepared lightweight wall has good use performance.

Description

technical field [0001] The invention relates to a method for preparing boards, in particular to a method for preparing a lightweight 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. Screen and crush the huge amount of corner waste produced by mining natural stone into sto...
