Embodiment 1

[0021] A low temperature resistant rubber and plastic foam insulation material, comprising the following components:

[0022] Main material: NBR8kg, PVC12kg;

[0023] Low temperature modifier: BR5kg;

[0024] Low temperature resistant plasticizer: DOA17kg;

[0025] Flame retardant: aluminum hydroxide 24kg;

[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 low temperature resistant rubber and plastic foam insulation material of this embodiment is as follows:

[0030] (1) Primary mixing rubber preparation: Weigh the raw materials according to the above components for later use, first put NBR into the internal mixer for pre-refinement for 40-50 seconds, then put other raw materials into the internal mixer for mixing, discharge the rubber at 155°C, and the discharged rubber The material is thinly passed on the mill f...

Embodiment 2

[0037] A low temperature resistant rubber and plastic foam insulation material, comprising the following components:

[0038] Main material: NBR8kg, PVC10kg;

[0039] Low temperature resistant modifier: EPDM5kg, EVA5kg;

[0040] Low temperature resistant plasticizer: DOA12kg, DOS8kg;

[0041] Flame retardant: aluminum hydroxide 23kg, magnesium hydroxide 14kg;

[0042] Foaming agent: azodicarbonamide 12kg;

[0043] Filler: talcum powder 2.1kg;

[0044] Anti-aging agent: anti-aging agent MB0.6kg, anti-aging agent DNP0.3kg.

[0045] In this example, the raw materials are weighed according to the above components, and the preparation method is the same as that in Example 1. The low-temperature-resistant rubber-plastic foam insulation material prepared in this example was placed in a freezer at -40°C for 72 hours, and it was still flexible when it was taken out and pressed by hand. It was normal when the tube was installed and there was no cracking.

Embodiment 3

[0047] A low temperature resistant rubber and plastic foam insulation material, comprising the following components:

[0048] Main material: NBR15kg, PVC20kg;

[0049] Low temperature modifier: BR2kg, EPDM2kg, EVA3kg;

[0050] Low temperature resistant plasticizer: DOA7kg, DOS8kg;

[0051] Flame retardant: aluminum hydroxide 10kg, magnesium hydroxide 12kg;

[0052] Foaming agent: azodicarbonamide 10kg;

[0053] Filler: talcum powder 10kg;

[0054] Anti-aging agent: anti-aging agent MB1kg.

[0055] In this example, the raw materials are weighed according to the above components, and the preparation method is the same as that in Example 1. The low-temperature-resistant rubber-plastic foam insulation material prepared in this example was placed in a freezer at -50°C for 72 hours, and it was still flexible when it was taken out and pressed by hand. It was normal when it was installed, and there was no cracking phenomenon.

[0056] From the above three examples, it can be see...

Abstract

The invention discloses a low-temperature resisting rubber-plastic foaming heat preservation material and relates to the field of rubber-plastic foaming heat preservation material. The material comprises the following components in percentage by weight: 8-20% of NBR (Nitrile-Butadiene Rubber), 10-25% of PVC (Polyvinyl Chloride), 4-10% of low-temperature resisting modifying agent, 10-20% of low-temperature resisting plasticizing agent, 20-40% of flame retardant, 10-15% of foaming agent, 5-20% of filling agent and 0.3-2% of anti-aging agent. The low-temperature resisting rubber-plastic foaming heat preservation material which is provided by the invention still has flexibility at a low temperature and is convenient to install.

Description

technical field [0001] The invention relates to the field of rubber and plastic foam insulation materials, in particular to a low temperature resistant rubber and plastic foam insulation material. Background technique [0002] At present, NBR / PVC system rubber-plastic foam insulation materials have been widely used in the fields of heat preservation of central air-conditioning systems and heat insulation of piping systems. However, in the low temperature environment (below -20°C) in winter in the north, the NBR / PVC system rubber and plastic foam insulation material will harden as the temperature drops, and even become brittle and cracked. The installation and construction in the environment are more difficult. Contents of the invention [0003] In view of the defects in the prior art, the purpose of the present invention is to provide a low temperature resistant rubber and plastic foam insulation material, which is still flexible at low temperature and easy to install. ...
