Abstract

The invention relates to a polyethylene thermal insulation material for a wall. The polyethylene thermal insulation material is prepared from the following components in parts by weight: 76-103 partsof polyvinyl chloride resin powder, 1-2 parts of hollow glass beads, 43-46 parts of coated glass beads, 2-7 parts of talcum powder, 5-8 parts of stabilizer, 3-7 parts of gypsum powder, 12-17 parts ofethylene-vinyl acetate copolymer, 1-3 parts of high-density polyethylene (HDPE), 2-4 parts of internal lubricant, 10-15 parts of kaoline, 3-12 parts of foaming agent, 100-120 parts of cement and 1-2 parts of sodium dodecyl sulfate. The polyethylene thermal insulation material for the wall has the advantages that the wall material prepared from various inorganic fillers is good in thermal insulation effect, environment-friendly as well as simple and convenient in preparation.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a polyethylene wall insulation material. Background technique [0002] The construction area of ​​new urban and rural buildings in my country is nearly 2 billion square meters each year, and the existing buildings are nearly 42 billion square meters. Building energy consumption has accounted for more than 27% of the country's total energy consumption. It is the energy saving of the envelope structure that has a particularly important position. In recent years, polystyrene foam board insulation has emerged as the times require. The polystyrene board insulation effect is very good, and the density is very low, which can reach below 100kg / m3, but its fatal flaw is that it is flammable and produces a lot of smoke after burning, so Its use is extremely limited. In recent years, fires in "CCTV Building", "Shanghai Teacher's Apartment" and "Shenyang Wanxin Hotel" caused by the burning...
