Abstract
The invention relates to the field of polyurethane, in particular to a polyurethane composite. The polyurethane composite comprises, by weight, 25-40 parts of ethyl acetate, 50-70 parts of isocyanate, 10-15 parts of nanometer magnesia powder, 5-8 parts of bamboo charcoal fiber, 1-2 parts of oxidizing agent and 1-3 parts of calcium carbonate, and preferably, the nanometer magnesia powder is 20-40nm in particle size. The polyurethane composite is mainly made of ethyl acetate and isocyanate, heat-conducting property is improved by dispersing magnesium powder in polyurethane, and heat conductivity coefficient of the polyurethane composite is increased through mutual synergistic effect of bamboo charcoal fiber and magnesium powder.
Description
Technical field
The present invention relates to polyurethane field, a kind of compound 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 compound 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.
Beneficial effect: compound polyurethane material is with ethyl acetate and isocyanate polyurethane as major ingredient, by polyurethane point
Scattered 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.
A kind of compound polyurethane material of the present invention, 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,
