Environment-friendly and highly-flame-retardant foam material for goods shelf and preparation method of foam material

Abstract

The invention discloses an environment-friendly and highly-flame-retardant foam material for a goods shelf and a preparation method of the foam material. The foam material is prepared from isocyanate and a composite according to the mass ratio of 1:1.9. The composite is prepared from, by mass, 15-18 parts of polyester, 13-18 parts of polyether 4113, 15-20 parts of polyether 450, 10-20 parts of polyether 403, 2.5-3.0 parts of silicone oil 8807, 55-65 parts of glass fibers, 1.2-1.8 parts of a catalyst DMP-30, 1.3-1.7 parts of an equilibrium catalyst HP-12, 1.1-1.5 parts of a catalyst HP-54, 3-4.5 parts of water and 36-38 parts of fire retardant DMMP. By the adoption of the materials and the method, the prepared foam material is high in flame retardation and not prone to combustion with fire, and therefore fire safety and personal safety are ensured; besides, the goods shelf made of the material is especially high in strength, high in density and capable of meeting the demand for storage of goods of different weights; due to the fact that all the raw materials used for the foam material are environmentally friendly and are matched reasonably, the foam material may not release toxic substances harmful for the human body and meets the environmental protection requirement.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to a shelf environment-friendly high flame-retardant foaming material and a preparation method thereof. Background technique [0002] The shelf is a commonly used device for storing goods in the industry. Its fire safety is very important. In addition to fire safety, the existing shelves also need to have high strength and high density requirements to store goods. In order to achieve For this purpose, people try various materials as shelf materials, but while pursuing high strength and high density, it also reduces safety, and it is often easy to cause fires when encountering accidents. Therefore, how to meet high strength It is a difficult technical problem to ensure safety due to high-density requirements and flame-retardant properties. In addition, the existing shelf materials are not environmentally friendly and have a great impact on the environment and h...
