High-strength gypsum-based flame-retardant board and preparation method thereof
The invention provides a high-strength gypsum-based flame-retardant board which is composed of a gypsum base body and surface protection paper arranged on the two sides of the gypsum base body, and the gypsum base body is prepared from the following raw materials in parts by weight: 100 parts by weight of gypsum; 5-20 parts by weight of an adhesive; 1-5 parts by weight of fiber; 0.1 to 2 parts by weight of starch; 0.2-2 parts by weight of a water reducing agent; 0.1-1 part by weight of a water repellent; 0.1-1 part by weight of a reinforcing agent; 0.1-2 parts by weight of a filler; 60 to 70 parts by weight of water; the adhesive is selected from more than two of acrylic homopolymer, polymethyl acrylate, polybutyl acrylate, polyvinyl acetate, polyvinyl alcohol, vinyl acetate-ethylene copolymer emulsion, styrene-acrylic emulsion and pure acrylic emulsion. Compared with the prior art, the high-strength gypsum-based flame-retardant board provided by the invention adopts the gypsum matrix with specific content composition, better interaction is integrally realized, and the product has a compact plate core structure, high density and high strength, high nail-holding power and excellent fireproof performance, and can achieve an A2-level flame-retardant effect.
本发明提供了一种高强石膏基阻燃板，由石膏基体与设置于所述石膏基体两侧的护面纸组成，所述石膏基体由包括以下组分的原料制备而成：石膏100重量份；粘合剂5～20重量份；纤维1～5重量份；淀粉0.1～2重量份；减水剂0.2～2重量份；憎水剂0.1～1重量份；增强剂0.1～1重量份；填料0.1～2重量份；水60～70重量份；所述粘合剂选自丙烯酸均聚物、聚丙烯酸甲酯、聚丙烯酸丁酯、聚醋酸乙烯酯、聚乙烯醇、乙酸乙烯‑乙烯共聚乳液、苯丙乳液和纯丙乳液中的两种以上。与现有技术相比，本发明提供的高强石膏基阻燃板采用特定含量组成的石膏基体，整体实现较好的相互作用，产品具有致密的板芯结构，兼具高密度及高强度性能，握钉力高，且防火性能优异，能够达到A2级别的阻燃效果。
