Abstract

The invention discloses a preparation method for a resin / cement composite light weight board. The resin / cement composite light weight board is processed and prepared by adopting compound resin, a water-based curing agent, alkali-proof glass staple fibers, a foaming agent, coal ash, calcium hydroxide powder, low-alkaline sulphate aluminium cement, a chemical additive and water in accordance with certain weight proportion. The chemical additive is prepared by adopting the following raw materials in accordance with certain weight proportion: carboxy methyl starch, polyacrylic acid, Alpha-cellulose, lignose, boric acid, calcium sulfonate and calcium chloride. Compared with traditional boards, the resin / cement composite forming board prepared by the preparation method has the advantages that the intensity and toughness are high, the hanging force is strong, the durability is good and the like; moreover, the resin / cement composite light weight board has the characteristics that the heat insulation, sound-proof and damp-proof performances, fire resistance, high durability, light weight, shock resistance are achieved, the manufacture process is simple, the construction is convenient and the like, and the resin / cement composite light weight board is an ideal environment-friendly wall body material.

Description

Technical field [0001] The invention relates to a method for preparing building materials, in particular to a method for preparing a resin / cement composite lightweight board. Background technique [0002] With the development of society, since the country implemented the wall reform policy, especially since the implementation of a series of mandatory standards and norms such as building energy efficiency standards, acceptance codes, new wall materials have shown a trend of rapid development. [0003] At present, there are more and more types of new wall materials. Among them, there are more applications, such as gypsum or cement lightweight partition board, color steel plate, aerated concrete block, steel wire mesh foam board, small concrete hollow block, gypsum Boards, gypsum blocks, ceramsite blocks, sintered porous bricks, shale bricks, solid concrete bricks, PC slabs, horizontal hole concrete wall panels, activated carbon walls, new partition wall panels, etc. [0004] Chinese p...
