Mineral halogen-free flame retardant geocell master batch

Abstract

The invention discloses a mineral halogen-free flame retardant geocell master batch which comprises the following raw materials in parts by weight: 121-130 parts of high density polyethylene, 0.7-2 parts of dinitrophenol, 2-3 parts of red phosphorus, 10-12 parts of talcum powder, 1-2 parts of decabromodiphenyl ethane, 0.1-0.2 part of diphenylthiourea, 1-2 parts of sorbitol, 0.5-1 part of coco fatty acid diethanol amide, 2-3 parts of polyamide wax powder, 0.6-1 parts of ricinoleic acid, 1-2 parts of tributyl citrate, 10-12 parts of blast furnace slag and 2-3 parts of rare earth additive. According to the mineral halogen-free flame retardant geocell master batch disclosed by the invention, high-strength boron carbide, attapulgite and rare earth elements are fully mixed by the added rare earth additive; the mixture is matched with calcium acetate as a preservative and polyvinylpyrrolidone as a stabilizer; under the surface treatment action of a silane coupling agent, the formed additive has the advantages of good surface strength, toughness, wear resistance and corrosion resistance as well as good stability; the comprehensive quality of the master batch can be effectively improved, and the adaptability to soil and the resistance to the outside pressure are improved.

Description

technical field [0001] The invention mainly relates to the construction field, in particular to a mine-used halogen-free flame-retardant geocell masterbatch. Background technique [0002] At present, the preparation of materials for geocells is relatively simple, and most of them are directly extruded from high molecular polymers and carbon black and other reinforcing agents. With the continuous development and progress of society, the research on soil environment, climate environment, etc. Or indirectly affect on-site construction and post-effects, therefore, it is necessary to further improve the performance of traditional simple geocells; [0003] Blast furnace slag is the waste discharged from the blast furnace when smelting pig iron. The main components are CaO, SiO2 and Al2O3. A lot of blast furnace slag waste is produced every year in my country. At present, it is widely used in roads, airports, foundation projects, railway ballast, Concrete aggregate and asphalt ...
