Foaming equipment achieving good foaming effect for production of polyurethane foam plastic

Abstract

The invention discloses foaming equipment achieving a good foaming effect for production of polyurethane foam plastic, and relates to the technical field of polyurethane foam plastic production equipment. The foaming equipment comprises a foaming box and two raw material boxes arranged above the foaming box; guide pipes are fixedly installed on sidewalls of the two raw material boxes correspondingly; one end of each guide pipe is fixedly provided with a telescopic hose; and one end of each of the two telescopic pipes is fixedly provided with a connecting pipe. The foaming equipment disclosed by the invention is reasonable in structure; a dosage of the raw materials of the foaming equipment is convenient to adjust and the raw materials are mixed uniformly, so that the foaming equipment achieves a better foaming effect; produced polyurethane foam plastic has better quality; waste of the raw materials is avoided; different types of polyurethane foam plastic can be produced; and the foaming equipment is applied to a wider range, increases the yield of the polyurethane foaming plastic, achieves a simple and smooth foaming process and a high production speed, enables the raw materials not to be adhered to the foaming boxes or damaged, and has higher practicability.

Description

technical field [0001] The invention relates to the technical field of polyurethane foam production equipment, in particular to a foaming equipment with good foaming effect for polyurethane foam production. Background technique [0002] Polyurethane foam is made of isocyanate and hydroxyl compound through polymerization and foaming. According to its hardness, it can be divided into two types: soft and hard. Among them, soft is the main variety. Generally speaking, it has excellent elasticity, softness, Elongation and compressive strength; good chemical stability, resistant to many solvents and oils; excellent wear resistance, 20 times larger than natural sponge; and excellent processability, heat insulation, adhesion and other properties, is a kind of Cushioning material with excellent performance, but the price is relatively high. Polyurethane foam is generally only used for cushioning packaging or cushioning materials for high-end precision instruments, valuable instrument...

AI Technical Summary

Problems solved by technology

[0003] Due to the fixed structure of the existing foaming equipment for polyurethane foam production, the dosage of foaming raw materials is inconvenient to adjust, and the foaming density will change with the dosage of foaming raw materials. , so that the quality of the polyurethane foam produced by the foaming equipment is not easy to control, resulting in poor foaming effect, the quality of the produced polyurethane foam is not up to standard, and the raw materials are wasted. For this reason, we propose a polyurethane foam production Foaming equipment with good foaming effect
