Problems solved by technology

This method uses specific flame retardant soaked particles after foaming, but this method is very troublesome to operate
Because the foamed particles are only more than ten kilograms per cubic meter, due to the low density, they will float in the flame retardant and cannot be completely soaked at all, so the improvement of flame retardant performance is limited.
[0004] CN104744885B discloses a resin composition, a graphite polystyrene board and a preparation method thereof, comprising: a thermosetting resin mixed liquid, a curing agent, and the curing agent includes, in parts by mass: 5-20 parts by mass of boric acid, benzenesulfonic acid 30-50 parts by mass, 10-30 parts by mass of p-toluenesulfonic acid, 0-20 parts by mass of ethyl sulfate, 5-10 parts by mass of magnesium oxide, 5-10 parts by mass of aluminum hydroxide, 5-10 parts by mass of aluminum silicate , 0.2-5 parts by mass of graphite particles, the thermosetting resin mixture includes: 60-80 parts by mass of phenolic resin, 20-40 parts by mass of furfural resin, 0.1-20 parts by mass of melamine formaldehyde resin, due to the addition of The thermosetting resin mixture and curing agent have improved the combustion performance of the graphite polystyrene board. However, the board is generally acidic, and the reaction with the alkaline mortar will easily cause the board to fall off.

Abstract

The invention provides a polystyrene foaming material. The polystyrene foaming material is prepared from polystyrene particles and slurry, wherein the slurry is prepared from the following componentsin parts by weight: 15 to 30 parts of a curing agent, 50 to 300 parts of phenolic resin, 1 to 6 parts of a foaming agent, 2 to 15 parts of a surfactant, 30 to 180 parts of a flame retardant and 0.05 to 3 parts of a lubricant, wherein the mass ratio of the polystyrene particles to the slurry is 1:(1 to 5). The polystyrene foaming material prepared according to a preparation method provided by the invention has the advantages that particles are not bonded; the used alkaline phenolic resin shows strong basicity and enables a thin plastering system to be more stable when being applied to a foam board, so that fall-off the board caused by the reaction between the board and mortar is prevented and the adhesion is higher; in addition, the insulation property of the board is improved and the flame-retardant performance is good.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a polystyrene foam material and a preparation method and application thereof. Background technique [0002] Due to its excellent properties, such as low water absorption, heat insulation, excellent dielectric properties, and good mechanical properties, polystyrene foam has become the most widely used external wall insulation material at this stage. But it is an organic hydrocarbon with an oxygen index of only 18%, which is a flammable material. Even if the fire source is removed, it can still continue to burn. During the burning process, it is accompanied by thick smoke and obvious shrinkage, and there is molten dripping with open flames. As a building material, polystyrene foam board must be treated with flame retardant. [0003] CN104292492A discloses a preparation method of a polystyrene foam board: (1) pre-hairing and curing expandable polystyrene particles; (2) dipping the c...
