In this embodiment, the cement-based fabric 120 is bonded to the non-woven fabric 110 by glue.

The cement base cloth 120 is bonded with the non-woven fabric 110 at a high temperature by using glue, so that the bonding force between the non-woven fabric 110 and the cement base cloth 120 is stronger, and the firmness of the cement synthetic base cloth 100 is improved, thereby better enhancing the strength and tensile property of the non-woven fabric 110, improving the alkaline condition of the cement base cloth 120, and avoiding the condition that the surface of the heat-insulating board is weathered due to the direct contact between the cement base cloth 120 and the board body.

Lime is an air hardening inorganic cementing material with calcium oxide as a main component, has better water retention and plasticity, is commonly used for improving the water retention of mortar in engineering, but has low hardening speed, low strength, poor water resistance and large drying shrinkage. Polyethylene is a thermoplastic resin prepared by ethylene polymerization, has excellent low temperature resistance (the lowest use temperature can reach-100 to-70 ℃), good chemical stability and can resist most of acid and alkali corrosion. Cellulose is macromolecular polysaccharide composed of glucose, and can be used as a water-retaining agent and a retarder of cement mortar to enable the mortar to have pumpability, and can also be used as an adhesive and a sticking enhancer. The emulsion powder is water-soluble redispersible powder, which is divided into ethylene/vinyl acetate copolymer, vinyl acetate/tertiary ethylene carbonate copolymer, acrylic acid copolymer and the like, and the powder adhesive is prepared by spray drying and takes polyvinyl alcohol as protective colloid. The powder can be quickly redispersed into emulsion after being contacted with water, and the redispersible emulsion powder has high binding capacity and unique properties, such as: water resistance, workability, heat insulation, and the like. The latex powder can enhance the water retention of the material and prevent the phenomena of rapid hardening, drying and cracking of cement mortar; the plasticity of the mortar is increased, and the construction workability is improved; the bonding performance of the mortar is improved, so that the mortar can bond substrates (such as polystyrene boards) better; the slipping phenomenon can be prevented during construction. Therefore, cement made of several materials has better plasticity, water retention, corrosion resistance and strength, and the cement base cloth 120 made of the cement base cloth has the excellent performances.

In this embodiment, the cement-based fabric 120 is a flexible cement-based coiled material facing. In this way, the plasticity of the cement base cloth 120 can be improved, and the bonding effect of the cement base cloth 120 and the non-woven fabric 110 is better, so that the stability of the cement composite base cloth 100 is improved.
