Embodiment 1

[0030] Pipe insulation tiles are composed of the following components in the following parts by weight:

[0031] 80 parts of urea-formaldehyde foam plastic powder; 2 parts of polyvinyl alcohol rubber powder; 0.3 part of cellulose ether; 0.8 part of waterproofing agent; 15 parts of water.

[0032] The urea-formaldehyde foamed plastic powder is made by crushing a urea-formaldehyde foamed plastic insulation board into 20-100 mesh powder. The preparation method of urea-formaldehyde foam plastic insulation board has been disclosed in the Chinese invention patent whose patent number is 200510046937.3 and publication number is CN1736936. Let's explain in detail:

[0033] The urea-formaldehyde foam insulation board is composed of the following components in the following parts by weight:

[0034] The urea-formaldehyde resin of 50 parts by weight, the sodium lauryl sulfate of 1.5 parts by weight, the phosphoric acid of 0.5 parts by weight, the oxalic acid of 0.5 parts by weight, the ...

Abstract

The invention relates to a pipe insulation tile which is produced by urea-formaldehyde foam powder and a preparation process. The pipe insulation tile is formed by the following components according to the ratio of parts by weight, urea-formaldehyde foam powder: polyvinyl alcohol gelatin powder: cellulose ether: waterproofing agent: water =80-120:0.5-2:0.1-0.3:0.2-0.8:5-15. The invention has small thermal conductivity factor, can effectively prevent or reduce heat in the surrounding environment from transmitting into devices, pipes and accessories under constant temperature, reduces cold loss, saves energy, prevents or reduces the temperature of cold dialectic in the devices and pipes under the constant temperature from increasing, and prevents the temperature of outer walls from lowering the temperature of the surrounding environment, and prevents the outer surface condensation of the pipe to damage a cold insulation structure, thereby prolonging the service life of cold insulation devices, and being beneficial for improving working environments. The pipe insulation tile has the advantages of corrosion resistance, anti-aging, excellent heat insulation and sound insulation value, light weight, convenient installation, durable service, long service life, environmental protection and beauty appearance.

Description

technical field [0001] The invention relates to a pipeline insulation tile and a preparation method thereof, in particular to a pipeline insulation tile made of urea-formaldehyde foam plastic powder and a preparation method thereof. Background technique [0002] At present, most pipeline insulation materials use polyurethane or rock wool. As a pipeline insulation material, polyurethane has the advantages of light weight, heat preservation, and heat insulation, so it is widely used in pipeline external insulation projects or construction. However, with the further improvement of environmental protection, energy saving and emission reduction, and fire protection engineering requirements, people have gradually discovered its shortcomings: polyurethane has poor fire resistance, and it will release a variety of toxic gases when burned, directly causing air pollution; and rock wool is harmful to the human body. Yes, rock wool will cause harm to the human respiratory system, skin, ...
