Embodiment 1

[0017] A method for preparing an insulation board for building exterior walls. The insulation board is made of expanded polystyrene foam material. The insulation board is calculated in parts by weight and consists of the following components: 100 parts of EPS beads, phenolic aldehyde 100 parts of resin, 2 parts of phosphoric acid, 4 parts of p-toluenesulfonic acid, 4 parts of deionized water, 5 parts of fillers, 8 parts of inorganic flame retardants, and 9 parts of organic flame retardants. The preparation method of the insulation board is as follows:

[0018] The first step: pre-expansion, put the weighed EPS beads into the pre-expansion machine, control the steam pressure to 0.5MPa, control the pre-expansion temperature to 85°C, and control the pre-expansion time to 5 minutes;

[0019] The second step: curing, the above-mentioned pre-expanded EPS beads are placed in the air for 24 hours for curing;

[0020] The third step: prepare the flame retardant glue, add the weighed phenolic ...

Abstract

The invention discloses a preparation method of a heat preservation plate of an outer wall of a building. The heat preservation plate is prepared by adopting an EPS (Expandable Polystyrene) foam material; the heat preservation plate is prepared from the following components in parts by weight: 100 parts of EPS beads, 100 parts of phenolic resin, 2 to 3 parts of phosphoric acid, 3 to 5 parts of para-toluenesulfonic acid, 3 to 6 parts of deionized water, 5 to 10 parts of filler, 5 to 15 parts of an inorganic flame retardant, 5 to 15 parts of an organic flame retardant. The preparation method ofthe heat preservation plate comprises the following steps: prefoaming, curing, preparing a flame-retardant adhesive and forming. According to the preparation method disclosed by the invention, the EPSfoam material is adopted as a heat preservation layer, the construction is convenient, the heat preservation performance is good, and recycling is easy; a flame-retardant system adopts a way that inorganic flame retardance and organic flame retardance are used at the same time, the problem that a flame-retardant effect of a single flame retardant is incomplete is solved, the functions of overcoming the shortcomings by learning from the strong points of each other and cooperating with each other can be achieved by using the inorganic flame retardant and the organic flame retardant at the sametime, and the flame-retardant effect is better.

Description

Technical field [0001] The invention relates to the field of building materials, in particular to a method for preparing an insulation board for building exterior walls. Background technique [0002] Building energy conservation is one of the main content of the implementation of the country’s “energy conservation and emission reduction”, and an important part of the implementation of the sustainable development of the national economy. Building heat preservation and heat insulation are important means of building energy conservation. The exterior wall area of ​​the building is large, and the heat loss through the exterior wall accounts for the vast majority of the total heat loss of the building. Therefore, the exterior wall insulation of the building is extremely important for the energy saving of the entire building. The insulation layer of a building generally has three forms, namely the inner insulation layer, the middle sandwich insulation layer and the outer insulation lay...
