[0002] At present, the decorative boards made of gypsum are basically used as ceiling decorative boards. It has the advantages of being beautiful and light, but it also has the following disadvantages: 1. The strength is not high, fragile and easy to break; Dust: Dust will stick to it after a long time, it will become dirty and dark, and it is difficult to clean; 3. Because the gypsum board has not been treated, both sides are covered with protective paper, which has poor flexural and compressive strength, and the protective paper can only protect The role of the surface, but can not play the role of strengthening the strength of gypsum board

Abstract
The present invention discloses a producing method of surface-protecting clothe used for cloth-surface gypsum dalle and its drapery intensifier. The surface-protecting clothe is made from smearing and brushing drapery intensifier on common drapery then through a certain technics. The said drapery intensifier is made of materials as pastem, fecula, gypsum, calcareousness and water. Besides it's added additive to obtain surface-protecting clothe with better effect. It is provides with following advantages: 1. its texture is hard and uneasy to be broken up, and its anti-stretching, anti-breaking and anti-pressing intensity has been greatly improved; 2. its hygroscopicity is strong, its permeability is high and it is slurry leakproof; 3. it has improved the cementing power between surface-protecting clothe and gypsum core, it is durable, not delaminating and uneasy to strip; 4. its fire-resistant ability has been improved; 5. its luster can be adjusted at will according to used pigment, and the produced surface-protecting clothes are artistic, beautiful and clean. Therefore the surface-protecting of the present invention is used to pack the gypsum board, which can strengthen the intensity of the gypsum board, and is a kind of new-style surface-protecting material of gypsum dalle.
Description
technical field [0001] The invention relates to building materials, in particular to a method for preparing a face-protecting cloth used for a cloth-faced gypsum decorative board and a slurry thereof. Background technique [0002] At present, the decorative boards made of gypsum are basically used as ceiling decorative boards. It has the advantages of being beautiful and light, but it also has the following disadvantages: 1. The strength is not high, fragile and easy to break; Dust: Dust will stick to it after a long time, it will become dirty and dark, and it is difficult to clean; 3. Because the gypsum board has not been treated, both sides are covered with protective paper, which has poor flexural and compressive strength, and the protective paper can only protect The role of the surface, but can not play the role of strengthening the strength of gypsum board. Contents of the invention [0003] The object of the present invention is to provide a preparation method and ...
