Abstract
The invention relates to the field of polyurethane and particularly relates to an easy-thermal-conducting type polyurethane material. The easy-thermal-conducting type polyurethane material is prepared from the following components in parts by weight: 25-40 parts of polyisoprene, 50-70 parts of isocynate, 10-15 parts of nano magnesium oxide powder, 5-8 parts of bamboo charcoal fibers, 1-2 parts of an oxidant and 1-3 parts of styrene; and preferably, the grain diameter of the nano magnesium oxide powder is 20nm-40nm. The polyurethane composite material provided by the invention takes the polyisoprene and the isocynate polyurethane as main materials; the heat-conducting performance is improved through dispersing magnesium powder into the polyurethane; furthermore, the bamboo charcoal fibers and the magnesium powder have mutual synergistic effect so that the heat-conducting coefficient of the polyurethane composite material is improved.
Description
Technical field
The present invention relates to polyurethane field, a kind of easily heat-conducting polyurethane material.
Background technology
Thermoplastic polyurethane (TPU) elastomer, be by the methyl diphenylene diisocyanate (MDI) containing NCO functional group with
Polyhydric alcohol (POLYOL) containing 0H functional group, Isosorbide-5-Nitrae butanediol (Isosorbide-5-Nitrae-BG) are mixing and make through extrusion, due to good springiness,
Physical property mechanical strength good, various is all fine, is therefore widely used in injection, extrusion, rolls and be dissolved into solution resin etc. and add
Work mode, is the commonly used plastic material of plastic cement processer, and its product made covers commercial Application and civilian required
The scope of product.TPU not only has the high-tension of brilliance, high-tensile strength, tough and ageing-resistant characteristic, and is ripe ring
Protect material；TPU has been widely used in electronic apparatus, automobile, articles for daily use etc. at present.But, the shortcoming of TPU is to lead
Hot property is poor.
Along with requirement for electronic product has lightweight, trend toward miniaturization, wherein to electrical and electronic component and automobile on the market
Electronic component has again high cooling requirements.But traditional Heat Conduction Material is generally metallic article, its distinguishing feature is high heat conduction, but
Metallic article proportion is relatively big, processing difficulties.The most common thermal conductive polymer material such as heat conduction PPS etc., it is mainly hard
Engineering plastics, it is impossible to meet the requirement for material flexibility of the automotive electronics subassembly product..
Summary of the invention
In order to make up the deficiencies in the prior art, the present invention provides a kind of and has that pliability is good, heat conductivity is high, the poly-ammonia of light weight
Ester composite.
The technical solution adopted for the present invention to solve the technical problems is: a kind of easily heat-conducting polyurethane material, according to weight portion
Meter, including following components:
Preferably, the particle diameter of described nano alumina powder is 20-40nm.
Preferably, described antioxidant be β (3,
5-di-t-butyl-4 hydroxyphenyl) propionate and the mixing of three (2,4-DTBP) phosphite ester
Thing.
Preferably, described β (3,5-di-t-butyl-4 hydroxyphenyl) propionate and three (2,4-bis-tertiary fourths
Base phenol) mass ratio of phosphite ester is 3: 5.
Beneficial effect: compound polyurethane material is with polyisoprene and isocyanate polyurethane as major ingredient, by polyurethane
Dispersion magnesium powder improves heat conductivility, additionally by bamboo carbon fiber and the mutual synergism of magnesium powder, improves compound polyurethane material
Heat conductivity.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
Embodiment, is expanded on further the present invention.
One of the present invention easy heat-conducting polyurethane material, in parts by weight, including following components:
Preferably, the particle diameter of described nano alumina powder is 20-40nm.
Preferably, described antioxidant be β (3,
5-di-t-butyl-4 hydroxyphenyl) propionate and the mixing of three (2,4-DTBP) phosphite ester
Thing.
Preferably, described β (3,5-di-t-butyl-4 hydroxyphenyl) propionate and three (2,4-bis-tertiary fourths
Base phenol) mass ratio of phosphite ester is 3: 5.
More than display describes the ultimate principle of the present invention, principal character and advantage.Skilled person will appreciate that of the industry,
The present invention is not restricted to the described embodiments, the principle that the present invention is simply described of the description in above-described embodiment and description,
Without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements are all
