Problems solved by technology

[0003] At present, the extruded polystyrene board used in the external wall insulation system has poor fire resistance and cannot meet the fire protection requirements in actual use. It is necessary to improve its flame retardancy
Since the skin of extruded board is smooth and has poor adhesion, it is difficult to achieve surface modification.
Patent CN102134882A discloses a method for improving the fire performance of extruded polystyrene boards in external wall insulation systems, and provides a new type of extruded polystyrene board composed of polymer emulsion, flame retardant, defoamer and cement. Board interface treatment agent, and then use this interface treatment agent to strengthen the extruded polystyrene board to improve its flame retardancy and surface adhesion, and the flame retardancy of the treated extruded polystyrene board is improved, but this This kind of coating material still has polymer materials, and it still has certain flammability, and its anti-ultraviolet aging resistance is poor, it is easy to turn white and crack, and its application performance in external wall insulation system is poor

Embodiment Construction

[0018] A highly flame-retardant and anti-aging extruded polystyrene board, the polystyrene board includes the following components by weight: carbon airgel powder 1 loaded with nano-zinc oxide, polystyrene resin monomer particles 65, white carbon black 1. Foaming agent ethanol 5. Flame retardant BDP 0.1.

[0019] The carbon airgel powder loaded with nano-zinc oxide has a particle size of 0.1 μm, and is formed by cross-linking and stacking carbon nanospheres loaded with nano-zinc oxide on the surface as a building unit.

[0020] A preparation method of a highly flame-retardant and anti-aging extruded polystyrene board, comprising the following steps:

[0021] (1) Preparation of carbon airgel powder loaded with nano zinc oxide

[0022] Preparation of organic zinc sol: mix zinc acetate, diethanolamine and ethylene glycol methyl ether, and stir for 2 hours at a temperature of 30°C and a stirring speed of 400r / min to obtain a mixed solution, and then leave the mixed solution to st...

Abstract

The invention discloses a high-flame-retarding anti-aging extruded polystyrene board which includes, by weight, 1-10 parts of carbon aerogel powder supporting nano ZnO, 65-100 parts of polystyrene resin monomer granules, 1-5 parts of filler, 5-10 parts of a foamer, and 0.1-5 parts of a flame retardant.

Description

technical field [0001] The invention relates to the technical field of extruded polystyrene boards, in particular to a highly flame-resistant and anti-aging extruded polystyrene board and a preparation method thereof. Background technique [0002] Extruded board is made of polystyrene resin supplemented by polymer, while heating and mixing, injecting catalyst, and then extruding out continuous closed-cell foamed rigid foam board, which has an independent closed cell structure inside. It is an environmentally friendly insulation material with high compression resistance, low water absorption, moisture resistance, airtightness, light weight, corrosion resistance, super anti-aging (almost no aging after long-term use), low thermal conductivity, etc. It is widely used in dry Wall insulation, flat concrete roof and steel structure roof insulation, low-temperature storage ground, low-temperature floor radiant heating under heating pipes, parking platforms, airport runways, highway...
