Abstract
The invention discloses special joint filling mortar for light partition wallboards. The special joint filling mortar comprises, by weight, 300-400 parts of cement, 100-140 parts of fly ash, 400-450 parts of fine sand, 30-60 parts of calcined gypsum powder, 2-10 parts of macromolecule xanthan gum powder, 1-10 parts of redispersible latex powder, 1-3 parts of starch ether, 1-3 parts of cellulose ether, 1-3 parts of set retarders, 40-60 parts of expansive agents, 2-8 parts of graphene oxide modified carbon fibers and 1-5 parts of water repellents. A mass ratio of the macromolecule xanthan gum powder to the redispersible latex powder is 2-7:1; an expansion coefficient of the calcined gypsum powder is 120-130, and a mass ratio of graphene oxide to carbon fibers is 0.05-0.1:1. The special jointfilling mortar for the light partition wallboards has the advantages that various components of the special joint filling mortar are selected, the weights of the various components are matched with one another, respective excellent properties of the various components are comprehensively utilized, the strength of the components is drawn, and accordingly the special joint filling mortar is high inbonding strength, tensile and compressive property and water retention rate and low in shrinkage.
Description
technical field [0001] The invention belongs to the technical field of building materials, and mainly relates to a joint-filling mortar special for lightweight partition boards and a preparation method thereof. Background technique [0002] Lightweight partition board is a new type of energy-saving wall material. It looks like a hollow floor wall material. There are male and female falcon grooves on both sides. When installing, you only need to stand up the board. After the male and female falcons are coated with a small amount of caulking mortar Just put it together. The advantages of lightweight partition boards are mainly manifested in light weight, high folding resistance, and good waterproof performance. This performance is in line with modern decoration concepts, and the market prospect is relatively broad. After the existing joint-filling mortar is used for a period of time, various degrees of cracking will occur, mainly vertical cracks and a small number of transver...
