Problems solved by technology

However, NBR / PVC system rubber and plastic foam insulation materials are used as thermal insulation materials in traditional building materials. The formula system contains PVC, chlorinated paraffin and other halogen-containing raw materials. When a fire occurs, it burns and releases a large amount of toxic smoke. and corrosive halogen acid, causing casualties far greater than the fire itself

Embodiment 1

[0022] A halogen-free rubber and plastic foam insulation material, comprising the following components:

[0023] Main material: NBR15kg, EVA13kg;

[0024] Halogen-free flame retardant: aluminum hydroxide 24kg;

[0025] Halogen-free plasticizer: tricresyl phosphate 14kg;

[0026] Foaming agent: azodicarbonamide 12kg;

[0027] Filler: talcum powder 11kg, clay 7kg, calcium carbonate 3.7kg;

[0028] Anti-aging agent: anti-aging agent MB0.3kg.

[0029] The preparation method of the halogen-free rubber and plastic foam insulation material in this example: take the above-mentioned component raw materials, put them into a 75L internal mixer for mixing, and generate the mixed rubber; the mixed rubber is cut into pieces and added to the extruder to be pressed out to form; the formed product Send it into a hot air oven for vulcanization and foaming; then cool and cut to make the final product.

Embodiment 2

[0031] A halogen-free rubber and plastic foam insulation material, comprising the following components:

[0034] Halogen-free plasticizer: tricresyl phosphate 20kg;

[0035] Foaming agent: azodicarbonamide 12kg;

[0036] Filler: talcum powder 2.1kg;

[0037] Anti-aging agent: anti-aging agent MB0.6kg, anti-aging agent DNP0.3kg.

[0038] In this example, the raw materials are weighed according to the above components, and the halogen-free rubber and plastic foam insulation material of this example is prepared according to the preparation method of Example 1.

Embodiment 3

[0040] Main material: NBR20kg, EVA18kg;

[0041] Halogen-free flame retardant: aluminum hydroxide 16kg, magnesium hydroxide 14kg;

[0042] Halogen-free plasticizer: tricresyl phosphate 17kg;

[0043] Foaming agent: azodicarbonamide 12kg;

[0044] Filler: talcum powder 2.1kg;

[0045] Anti-aging agent: anti-aging agent MB0.6kg, anti-aging agent DNP0.3kg.

[0046] In this example, the raw materials are weighed according to the above components, and the halogen-free rubber and plastic foam insulation material of this example is prepared according to the preparation method of Example 1.

[0047] According to the national fire protection standard "GB8624", the safety grades of the halogen-free rubber and plastic foam insulation materials prepared in the above three examples were tested, and the results are as follows:

[0048] Test items Example 1 Example 2 Example 3 Density (kg / m 3 ) 48 47 47 Oxygen Index 33 34 32 Smoke Density (Grade) 40 ...

Abstract

The invention discloses a halogen-free rubber-plastic foam heat insulating material, relating to the field of rubber-plastic foam heat insulating materials. The product comprises the following components in percentage by weight: 13-30 percent of NBR (Nitrile-Butadiene Rubber), 13-30 percent of EVA (Ethylene Vinyl Acetate), 24-40 percent of halogen-free flame retardant, 14-20 percent of halogen-free plasticizing agent, 12-20 percent of foaming agent, 2-25 percent of filling agent and 0.3-2 percent of anti-aging agent. The halogen-free rubber-plastic foam heat insulating material releases a small amount of toxic gas during combustion, and causes little harm to human bodies.

Description

technical field [0001] The invention relates to the field of rubber and plastic foam insulation materials, in particular to a halogen-free rubber and plastic foam insulation material. Background technique [0002] In the fire accidents in recent years, more than 80% of the deaths were caused by the dense smoke and poisonous gas produced by the burning of building materials. As more and more public places and large buildings are put into use, the fire protection of buildings and the impact on the human body during combustion have received extensive attention. However, NBR / PVC system rubber and plastic foam insulation materials are used as thermal insulation materials in traditional building materials. The formula system contains PVC, chlorinated paraffin and other halogen-containing raw materials. When a fire occurs, it burns and releases a large amount of toxic smoke. and corrosive halogen acid, causing casualties far greater than the fire itself. Contents of the inventio...
