Fireproof polystyrene heat preservation plate and preparing method thereof

Abstract

The invention provides a fireproof polystyrene heat preservation plate and a preparing method thereof. The fireproof polystyrene heat preservation plate is prepared from polystyrene particles coated with a fire retardant, and the fire retardant is prepared from urea resin, alkyd resin, aluminium hydroxide, ammonium polyphosphate, pentaerythritol, assistant, antifoaming agent and pigment. According to the fireproof polystyrene heat preservation plate and the preparing method thereof, the fireproof-isolation-cabin isolating theory is adopted, when the heat preservation plate is burned, the fire retardant on surface layers of beads form a compact carbon layer, it can be effectively prevented that polystyrene beads inside the heat preservation plate are burned through flames, and therefore the burning performance level of the heat preservation plate reaches the A2 level.

Description

Technical field [0001] The invention relates to a fireproof polystyrene insulation board and a preparation method thereof. The board is suitable for the technical field of building materials, and is particularly suitable for the insulation of building exterior wall external insulation systems and other enclosure structures. Background technique [0002] In my country, the external walls of new energy-saving buildings and energy-saving renovation of existing buildings mainly adopt external wall insulation technology, and insulation materials play a vital role in the external insulation system. There are two main types of thermal insulation materials: inorganic thermal insulation materials, such as rock wool, glass wool, foamed cement board, etc., have high density, good fire resistance, and can reach A, but the production process of these materials is also a process of high energy consumption. It does not meet the national call for building energy conservation, with high thermal c...

AI Technical Summary

Problems solved by technology

There are two main types of thermal insulation materials: inorganic thermal insulation materials, such as rock wool, glass wool, foamed cement board, etc., have high density and good fire resistance, which can reach A, but the production process of these materials is also a high energy-consuming process. It does not meet the national call for building energy conservation. It has high thermal conductivity and poor thermal insulation performance; organic thermal insulation materials, such as molded polystyrene insulation boards, extruded polystyrene insulation boards, polyurethane insulation boards, etc., have excellent thermal insulation performance and low weight. Light, that is, the fire performance is relatively poor

[0003] The current technology is to improve the fire performance of organic thermal insulation materials, generally by adding flame retardants or graphite modification, but the highest flame retardant effect can reach B1 level, the effect is not obvious, and most flame retardants are added when adding Odor, corrosion, and toxic fumes will be produced in the event of a fire, seriously endangering human life
