Embodiment Construction
[0022] In an embodiment of the present invention, a method for preparing EPS foam products comprises the following components: 60-70 parts of polystyrene particles, 20-25 parts of benzene, 60-70 parts of absolute ethanol, 20-22 parts of ethylene glycol Diethyl ether, 8-10 parts of soluble pentane and 5-6 parts of brominated polystyrene, the preparation method comprises the following steps:
[0023] S1. Foaming: 60-70 parts of polystyrene particles, 20-25 parts of benzene, 60-70 parts of absolute ethanol, 20-22 parts of ethylene glycol ether, 8-10 parts of soluble pentane and 5-6 parts After the brominated polystyrene is uniformly mixed, it is fed into the foaming machine for heating and foaming to make it expand, and the density reaches the set density to obtain the mixture;
[0024] S2, ripening: the inside of the mixture obtained in the step S1 is infiltrated by air, and the internal and external pressure of the mixture is kept in balance;
[0025] S3. Forming: Fill the mol...

Abstract
The invention relates to the technical field of EPS foam production, and discloses a preparation method of an EPS foam product. The EPS foam product comprises the following components: 60-70 parts of polystyrene particles, 20-25 parts of benzene, 60-70 parts of absolute ethyl alcohol, 20-22 parts of glycol ether, 8-10 parts of soluble pentane and 5-6 parts of brominated polystyrene. The preparation method comprises the following steps: S1, foaming; S2, curing; S3, forming; and S4, cutting. The material is composed of the polystyrene particles, the benzene, the absolute ethyl alcohol, the glycol ether, the soluble pentane and the brominated polystyrene, the polystyrene particles are composed of sodium dodecyl benzene sulfonate, polyvinyl alcohol, calcium phosphate, styrene, auxiliaries and calcium carbonate, and therefore, the product has excellent tensile resistance, shear resistance, bending resistance and compression resistance; and in the using process of the product, the product is not easy to damage due to external force, long in service life, large in linear elasticity change range, good in elastic property and capable of bearing large pressure.
Description
technical field [0001] The invention relates to the technical field of EPS foam production, in particular to a preparation method of EPS foam products. Background technique [0002] EPS foam is a white object made of polystyrene foam particles containing volatile liquid foaming agent and heated by a preheated mold. It has structural characteristics such as micro-closed cells. It has light weight, shock resistance, drop resistance, Heat insulation, sound absorption, heat preservation, self-extinguishing, environmental protection, anti-aging, low cost, and convenient construction are widely used in construction and packaging industries, mainly used in building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicles, Ship insulation and heat insulation, floor heating and decorative carving and many other aspects. [0003] The Chinese patent discloses the preparation method of flame-retardant EPS foam insulation board and its board (authoriz...
