Abstract

The invention discloses a high-performance core material, which is prepared from the following raw materials: cement, coal ash, polystyrene particles, sand, resorcinol, maleic anhydride, zeolite powder, ethylene phosphate, a foaming agent, a foam stabilizer, hydrogen peroxide, tert-butyl peroxypivalate, trimethylolpropane tri (3-aziridinyl propionate), acetylacetone, 1, 2-cyclohexanediamine, 2, 2, 4, 6-tetramethyl-1, 3-pentanediol, 1, 2, 4-tetramethyl-1, 3-pentanediol, 1, 2, 4-tetramethyl-1, 3, 4-tetramethyl-1, 3, 4-tetramethyl-1, 3, 4-tetramethyl-1, 3, 4-tetramethyl-1, the component A is prepared from 1, 2-di (tert-butylperoxy) butane, octenyl succinic acid modified starch and water; the high-performance core material is prepared through the steps of slurry preparation, foam liquid preparation, raw material mixing and the like. The compressive strength of the polyphenyl granule light partition wall board made of the core material is 5.2 MPa or above, which indicates that the compressive strength of the polyphenyl granule light partition wall board made of the core material is good, and is superior to the technical index that the compressive strength of the light partition wall board is larger than or equal to 3.5 MPa according to the national standard requirement of Lightweight Partition Wall Board for Building (GB / 23451-2009).

Description

【Technical field】 [0001] The invention relates to the field of building materials, in particular to a high-performance core material, a preparation method and its application in the preparation of polystyrene particle lightweight partition boards. 【Background technique】 [0002] With the improvement of living standards, the simple sound insulation and shockproof of wall panels can no longer meet people's living needs. The current wall insulation is mainly an external bonding process, which has complex construction, high cost, small safety factor, and poor durability. Existing building exterior walls mostly use aerated concrete blocks, cement hollow blocks, furnace slag hollow blocks and Cement, gypsum hollow slats, etc. also have the disadvantages of poor thermal insulation effect and low strength. [0003] The functional requirements of lightweight partition walls refer to the requirements for sound insulation, heat preservation, fire prevention, waterproof, earthquake res...
