Abstract

The present invention discloses an antimony-based compound flame retardant for silicate fiberboard and a preparation method thereof, and belongs to the fields of material and chemical engineering. The antimony-based compound flame retardant comprises the following components by weight: 50-60 parts of antimony trioxide, 20-30 parts of calcium silicate, 4-10 parts of zinc borate, 3-10 parts of hydrotalcite and 3-5 parts of a modifier. The antimony-based compound flame retardant is prepared by the steps of antimony trioxide modification, raw material mixing and screening. The present invention employs antimony trioxide, zinc borate, hydrotalcite and modifier for the preparation of the compound flame retardant, and improves the refractoriness and processing property of the fireproof plate in reducing the amount of antimony. Meanwhile, the raw materials do not contain halogen or heavy metals such as lead and mercury, and do not produce harmful gases or waste in usage.

Description

【Technical field】 [0001] The invention belongs to the fields of materials and chemical industry, and in particular relates to an antimony-based composite flame retardant for silicate fiber boards and a preparation method thereof. 【Background technique】 [0002] Silicate fiberboard is made of calcareous materials, siliceous materials and other cementitious materials, as well as reinforcing fibers (mainly cellulose fibers, alkali-resistant glass fibers, etc. New lightweight panels. The difference between silicate fiberboard and ordinary calcium silicate board is that the amount of reinforcing fiber in the board is more than 10%, so it has low apparent density, moisture-proof, moth-proof, mildew-proof and good processability (can be nailed, sawed, In addition to the various advantages that ordinary calcium silicate boards also have, such as planing, drilling, bonding, etc.), silicate fiberboards also have excellent properties such as high strength, shrinkage and swelling when ...
