Problems solved by technology

As a new type of insulation board, polystyrene board can stand the test of time. As far as the current fire and flame retardant effect is concerned, if it continues, fire hazards will cause immeasurable losses to the society
In particular, polystyrene boards are made of polystyrene foam, which can burn a little under an open flame. Some manufacturers add flame retardants to meet the flame retardant requirements during the production process, which is costly and ineffective.
In order to reduce costs, some enterprises do not add flame retardants and the results fail to meet the standard requirements, thus bringing safety hazards to consumers

Embodiment 1

[0025] (1) PSP thermosetting polystyrene board:

[0026]

[0027] The above quality scores total 300%

[0028] (2) Process flow:

[0029] polystyrene

[0030] Foaming agent→pre-foaming→adding graphite and phenolic resin→curing→molding→cooling→foam products

[0031] Dispersant

[0032] (3) Key points of process operation:

[0033] ①Feeding Add the screened beads from the hopper, pass through the fan and cyclone feeder, and enter the kettle from the hopper of the reaction kettle. The dispersant soap powder is pre-dissolved in the dissolving pot and then sent to the reaction kettle, and a certain amount of water is added, and then the agitator is started to stir evenly. Finally, use a reciprocating pump to feed the foaming agent into the kettle through the high-level metering tank.

[0034] ②Impregnation, absorption and feeding are completed, and the jacket is passed through the reaction kettle to heat up the temperature. At this time, the foaming agent accelerates the v...

Abstract

Polystyrene undergoes chemical foaming to be used as a raw material, and special graphite and imported resin are added, mixed and heated and undergo extrusion moulding. By a particle fireproof isolating membrane technology and through copolymerization modification, EPS monomer particles have the same characteristics with a fireproof substance. By a composite technology, a fireproof isolating membrane is formed on the surface of each particle such that each particle forms a relatively independent organic granular fireproof unit. When in fire, an insulated continuous honeycomb structure is formed to obstruct flame propagation and penetration and completely eradicate combustion. The PSP thermosetting polystyrene board is a nontoxic green and environmental-protection product with fireproof thermal-insulation performance, economy, durability, dimensional stability and light weight. The product has a better fireproof effect than a general polystyrene board, and has more obvious superiority and a better development prospect.

Description

[0001] 1. Technical field [0002] This product is a thermosetting flame-retardant polystyrene board, which is used in related building waterproof and thermal insulation projects. [0003] 2. Background technology [0004] The external thermal insulation system of building exterior walls is a system that involves multiple links such as material properties, materials, wall base, environment, technology, quality management, design, application, and construction. As a new type of insulation board, polystyrene board can stand the test of time. As far as the current fire and flame retardant effect is concerned, if it continues, the fire hazard will cause immeasurable losses to the society. In particular, polystyrene boards are made of polystyrene foam, which can burn a little under open flames. Some manufacturers add flame retardants to meet the flame retardant requirements during the production process, which is costly and ineffective. In order to reduce costs, some enterprises do...
