Hot property fire resistance, mechanical performance etc., test result is shown in Table 2.
The performance test results of the embodiment 1~4 of table 2 and comparative example 1~2
Toughener is added in comparative example 1, no plasticizer, material stiffness is stronger, and deformability is weak.
Toughener is substituted with plasticizer in comparative example 2, material stiffness declines, and elongation at break and amount of deflection have improvement, led
Hot coefficient is also higher, extrudes current reduction 20%.
From embodiment 1~4 as can be seen that adding toughener and plasticizer so that material bending modulus declines to a great extent simultaneously,
Impact strength, elongation at break and amount of deflection all substantially increase simultaneously, and illustrating the ductility of material becomes more preferable, resists deformability
Enhancing.Composite tensile strength remains at more than 40MPa, higher than the intensity of general-purpose plastics (such as polypropylene PP), energy
Enough meets the needs of products such as LED radiator are to intensity.For embodiment 3 compared with comparative example 1, the addition of plasticizer makes extrusion electric current
Decline 10% or so, but heat conductivility is not influenceed substantially.The decline of electric current means that material flowability is more preferable, can use
The bigger production capacity of lower processing temperature or acquisition, in terms of energy consumption and production efficiency, therefore is very significant.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
