Embodiment Construction

[0021] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0022] This embodiment discloses a high-efficiency flame-retardant EPS foam production process. The raw material of foamed plastic products is mixed with high polymer and additives. The foam production process includes the following steps:

[0023] Step 1: Prepare raw materials, mix EPS with fillers, and add additives to process into semi-finished EPS raw materials;

[0024] Step 2: Pre-foaming, take out the sealed EPS raw material from the raw material warehouse, lift it up mechanically and pour it into the hopper of the steam foaming machine, enter the screw feeder to be heated by steam, and then feed the steam continuously and quantitatively by the screw rotation In the lower part...

Abstract

The invention discloses a high-efficiency flame retardant EPS foam production technology. The EPS foam production technology is superior in curing effect, high in product forming speed and high in stability. Moreover, production cost is low, water-cooling time is greatly shortened, the moisture content of produced products is low and can be controlled to be smaller than or equal to 3%, and product quality is greatly improved. Meanwhile, production efficiency of the products is improved.

Description

technical field [0001] The invention relates to a foam production process, in particular to a high-efficiency flame-retardant EPS foam production process. Background technique [0002] EPS is a rigid cellular foam of polystyrene (PS), which has good heat insulation and shock absorption, high compressive strength, very light weight and moisture resistance, and its uses include building heat insulation and sound insulation, side walls and Covering of inner walls, packaging materials and disposable packaging containers, etc. Among them, the existing EPS foam production cost is high, the production cycle is long, the stability of the foam production process is poor, and the vacuum effect in the molding process is poor, and the water cooling time is long Long, the product has a high moisture content, so it is particularly important to solve this type of problem. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention discloses a hi...
