Abstract

The invention discloses a quaternary phosphonium insulation board material, which is composed of the following raw materials (by weight): 10-13 parts of hollow glass beads, 10-15 parts of methyl cellulose, 7-8 parts of 2-mercaptobenzothiazole, 10-14 parts of allyltriphenylphosphonium bromide, 0.01-0.012 part of an initiator, 180-220 parts of styrene, 5-7 parts of ammonium persulfate, 30-40 parts of tetrabutyl titanate, 0.7-1 part of sp-8, and 7-12 parts of an ac foaming agent. With titanium sol introduced, mechanical properties of sheet plate products can be effectively improved, and a good synergistic antibacterial effect can be achieved when blended with quaternary phosphonium salt. Thereby, comprehensive quality of the finished product material is improved.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a quaternary phosphonium thermal insulation board material and a preparation method thereof. Background technique [0002] Expanded polystyrene resin has a wide range of uses. Due to its high strength, light weight, excellent thermal insulation performance and high energy absorption capacity, it can be used as a variety of instruments, valuables, precision instruments, vegetables and fruits and aquatic products. and other packaging materials; and because of its excellent characteristics such as low thermal conductivity, low water absorption, good electrical insulation, sound insulation, moisture resistance, and simple molding process, it is widely used in roadbed laying of roads and bridges, housing construction, fishing and fishing. Insulation materials in the refrigeration industry, etc. Among them, as an excellent building material, expanded polystyrene resin is mainly us...
