[0002] GB8624-97 divides the combustion performance of building materials into the following grades: Grade A: non-combustible building materials: A-grade WW insulation materials that hardly burn; B1 grade: flame-retardant building materials: flame-retardant materials have better It is difficult to catch fire when it encounters an open flame or high temperature in the air, and it is not easy to spread quickly; B2 level: flammable building materials: combustible materials have a certain flame retardant effect. Under the action of high temperature, it will immediately catch fire and burn, which will easily lead to the spread of fire, such as wooden pillars, wooden roof trusses, wooden beams, wooden stairs, etc.; B3 level: flammable building materials: without any flame retardant effect, easy to burn, fire hazard very big
[0003] In order to improve the performance of the wall, the composite insulation board came into being, but at present the composite board only plays its own role, and there is no composite board with the function of 1+1 greater than 2. In addition, its connection strength with the wall is low and it is easy to fall off

Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings.
[0014] Such as Figure 1~2 As shown, a thermosetting modified polystyrene board includes a heat insulation unit 2 and a fireproof unit 1. The heat insulation unit 2 is composed of several EPS foam balls, and the fireproof unit 1 is a continuous honeycomb network structure. The EPS foam is small The balls are set in the mesh structure of the fireproof unit 1, and the connected honeycomb mesh structure of the fireproof unit 1 wraps each EPS foam ball and separates the EPS foam balls to form several isolation compartments. 1 is phenolic resin.
[0015] In the technical solution, each EPS foam ball is provided with a closed-cell cavity.
[0016] In this technical solution, the heat insulation unit 2 composed of several EPS foam balls is arranged in a specific shape, and then liquid phenolic resin is injected into the gap of the heat insulation unit 2, and the liquid phen...

The invention discloses a thermosetting modified polystyrene board, which comprises a heat insulation unit and a fireproof unit. The heat insulation unit is formed by a plurality of EPS foam balls, the fireproof unit is in a continuous honeycomb reticular structure and made of phenolic resin, and the EPS foam balls are arranged in the reticular structure of the fireproof unit, wrapped by the continuous honeycomb reticular structured of the fireproof unit and partitioned by the same to form a plurality of isolation cells. The polystyrene board is capable of meeting the demand of energy saving and also has excellent fireproof effects; owing to a unique composite microstructure, difficulty in comprehensive balance of various performance indexes including heat preservation, density water absorption and the like of heat insulation materials is solved successfully, and requirements of energy saving and heat insulation of buildings are completely met.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a functional building wall, in particular to a thermosetting modified polystyrene board. Background technique [0002] GB8624-97 divides the combustion performance of building materials into the following grades: Grade A: non-combustible building materials: A-grade WW insulation materials that hardly burn; B1 grade: flame-retardant building materials: flame-retardant materials have better It is difficult to catch fire when it encounters an open flame or high temperature in the air, and it is not easy to spread quickly; B2 level: flammable building materials: combustible materials have a certain flame retardant effect. Under the action of high temperature, it will immediately catch fire and burn, which will easily lead to the spread of fire, such as wooden pillars, wooden roof trusses, wooden beams, wooden stairs, etc.; B3 level: flammable building materials: without an...
