Environment-friendly high-flame-resistance foaming material of afforestation bark model and preparation method thereof

Abstract

The invention discloses an environment-friendly high-flame-resistance foaming material of an afforestation bark model and a preparation method thereof. The environment-friendly high-flame-resistance foaming material is prepared from isocyanate and a combined material according to a mass ratio of 1 to 0.4; the combined material specifically is prepared from the following components in parts by mass: 32-38 parts of polyester 3628, 68-72 parts of polyether 330, 25-28 parts of polyether 403, 35-50 parts of polyether 4110, 25-40 parts of polyether 135, 3.2-3.6 parts of silicone oil 8803, 1.5-2.5 parts of a catalyst A33, 1.2-2.2 parts of a powerful catalyst HP-50, 4.8 parts of water and 30-38 parts of a flame retardant DMMP. After adoption of the materials and the method thereof, as the formula components are reasonable in collocation and the preparation method is appropriate, the prepared foaming material is high in flame resistance and low in possibility of combustion in fire, so that the fire protection safety and the personal safety are guaranteed; in addition, all the environment-friendly raw materials are collocated, and materials poisonous and harmful to a human body are not released, so that the requirement on environment friendliness is met.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to a green bark modeling environment-friendly high flame-retardant foaming material and a preparation method thereof. Background technique [0002] The green bark shape is a commonly used decorative item in life, and its fire safety is very important. In addition to the fire safety, the existing green bark shape also needs to have environmental protection requirements. However, the existing green tree Leather modeling materials are not environmentally friendly and have a great impact on the environment and harm to the human body. For this reason people try various materials as the material of afforestation bark molding to meet above-mentioned two kinds of requirements simultaneously, but also make safety reduce while pursuing environmental protection, often occur and easily cause fire situation to occur when encountering breakdown or accident, Therefore, how ...

[0002] The green bark shape is a commonly used decorative item in life, and its fire safety is very important. In addition to the fire safety, the existing green bark shape also needs to have environmental protection requirements. However, the existing green tree Leather modeling materials are not environmentally friendly and have a great impact on the environment and human health

For this reason people try various materials as the material of afforestation bark molding to meet above-mentioned two kinds of requirements simultaneously, but also make safety reduce while pursuing environmental protection, often occur and easily cause fire situation to occur when encountering breakdown or accident, Therefore, how to meet the needs of environmental protection and have flame retardant properties to ensure safety is a difficult technical problem to solve
