A-level flame-retardant modified polystyrene board heat-insulating system

Abstract

The invention discloses an A-level flame-retardant modified polystyrene board heat-insulating system, which comprises a base layer, a bonding layer, a heat-insulating layer, a plastering layer and a decorative finish layer sequentially from inside to outside, wherein the heat-insulating layer, the bonding layer and the base layer are fixed through connecting pieces; the heat-insulating layer includes an A-level flame-retardant modified polystyrene board; and the A-level flame-retardant modified polystyrene board comprises the following components in parts by weight: 20 to 25 parts of flame-retardant polystyrene resin, 0.4 to 0.5 part of foaming agent, 40 to 50 parts of talcum powder, 6 to 10 parts of aluminum hydroxide, 2 to 4 parts of surfactant and 3 to 5 parts of curing agent. The fireproof performance of the system reaches level A, so the defect that the existing traditional organic heat-insulating board heat-insulating system has low fireproof performance is solved; and the heat-insulating layer of the system adopts the A-level flame-retardant modified polystyrene board and is low in heat conductivity coefficient, so various potential quality hazards in slurry heat-insulating systems that on-site construction quality is difficult to control, heat-insulating performance cannot reach to the standard, and hollowing, dropping and cracking phenomena occur easily are overcome.

Description

technical field [0001] The invention relates to a building energy-saving technology, in particular to a class A flame-retardant modified polystyrene board heat preservation system. Background technique [0002] At present, building energy consumption has been ranked alongside industrial energy consumption and transportation energy consumption, and has become the three "big energy consumers" in my country's energy consumption. In particular, building energy consumption has shown a sharp upward trend along with the continuous increase in the total number of buildings and the improvement of living comfort. my country's buildings not only consume high energy, but also have low energy utilization efficiency. The energy consumption per unit of building is 2 to 3 times higher than that of countries under the same climate conditions. In my country's current urban housing construction, there are generally problems such as poor thermal insulation and air tightness of the envelope str...

Problems solved by technology

The main forms of external wall thermal insulation in the current price segment include: traditional organic thermal insulation board (EPS / XPS / PU) external wall thermal insulation system, inorganic thermal insulation material (foamed cement board / vitrified microbead thermal insulation mortar) wall thermal insulation system, etc., the above-mentioned Several kinds of thermal insulation systems have certain defects. Although the thermal insulation performance of the traditional organic board thermal insulation system is good, its fire performance is poor and the toxicity of the combustibles becomes its weakness; the inorganic thermal insulation system has excellent fire performance, but due to the Some shortcomings of the material itself (such as brittle surface, easy pulverization, slag drop, low bond strength, high water absorption, etc.), and its thermal insulation performance is generally difficult to meet the requirement of 65% building energy saving, which greatly limits this kind of thermal insulation material. scope of use
