Problems solved by technology

[0007] 1. The flame retardant performance mainly depends on the flame retardant and nano-scale graphite. The flame retardant is usually hexabromododecane, which can capture the free radicals of the reaction during combustion and stop the chain reaction. However, since the flame retardant participates in the reaction and is consumed after being heated, the flame retardant effect is not good when burning continuously. In addition, hexabromododecane is made into a flame retardant and will release toxic substances when used in foam insulation materials. And it will quickly produce toxic smoke when encountering a fire; nano-scale graphite is dispersed in polystyrene particles, which can play a certain role in flame retardancy, but due to process and cost reasons, the content is small, and there is no great flame retardancy Most of the combustion performance grades can only reach the B2 level, barely reaching the B1 level
[0008] 2. Ordinary graphite polystyrene board is a thermoplastic insulation material. When it is on fire, the insulation board will deform and flow, and the fire will spread easily.

Abstract

The invention provides a resin composition, a modified graphite polyphenyl board and a preparation method thereof and aims at solving the problems that the graphite polyphenyl board has poor flame retardant property, a board deforms and runs and a fire can be spread easily in the prior art. The resin composition, the graphite polyphenyl board and the preparation method thereof have the advantages that thermosetting resin mixed liquor and a curing agent are added, so that combustion performance level of the graphite polyphenyl board is improved; meanwhile, the board has thermosetting property, so that volume is almost constant when the graphite polyphenyl board catches a fire and burns, and the graphite polyphenyl does not run and is self extinguished when being away from the fire.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a resin composition, a graphite polystyrene board and a preparation method thereof. Background technique [0002] Graphite polystyrene board is a graphite polystyrene foam plastic board with closed-cell structure, which is made by heating and pre-foaming expandable graphite polystyrene particles in a mold. It is widely used in the interior and exterior walls of buildings. The field of thermal insulation has developed rapidly at home and abroad this year. [0003] The main raw materials of ordinary graphite polystyrene board are polystyrene, graphite, pentane, etc. Although the combustion performance level can reach B1 level, but the oxygen index is not high, and it is a thermoplastic material, which cannot withstand long-term baking and cannot meet the relevant requirements. standard requirement. [0004] Graphite polystyrene board generally adopts the foll...
