Abstract
The present invention relates to a kind of foamed plastics blowing promotor, the blowing promotor has following structural：
Description
Technical field
The present invention relates to plastic applications, specifically, the present invention relates to a kind of foamed plastics blowing promotor.
Background technology
With the fast development of the special dimensions such as space flight and aviation, it is desirable to which core material has higher intensity, rigidity and resistance to
It is hot.And universal foam plastics (such as PE ,/PP) high-temperature capability is poor, high temperature deformation make it that the dimensional stability of sandwich meets with
To destruction, it is impossible to meet the use requirement in above-mentioned field.The foamed plastics that the country is used in above-mentioned field at present is mainly from moral
State's import, it is expensive.In order to break the situation of long-term dependence on import, cost, bubble of the research and development with independent intellectual property right are reduced
Foam plastics have highly important strategic importance.
The content of the invention
It is an object of the invention to provide a kind of foamed plastics blowing promotor.
In order to realize the purpose of the present invention, the present invention provides a kind of foamed plastics blowing promotor, the blowing promotor tool
There is following structural：
Preferably, the blowing promotor can be granule.
The present invention also provides purposes of the compound with following formula in as foamed plastics blowing promotor：
Foamed plastics prepared by the present invention has excellent mechanical performance, heat resistance and moulding processability, is engineering
The preferable core material that structure is selected.
Embodiment
Below by way of the description of embodiment, the invention will be further described, but this is not the limit to the present invention
System, those skilled in the art are according to the basic thought of the present invention, and various modifications may be made or improves, but without departing from this
The basic thought of invention, within the scope of the present invention.
Embodiment 1
Weigh 500 kilograms of acrylonitrile, 350 kilograms of methacrylic acid, 30 kilograms of acrylamide, dibenzoyl peroxide 25,000
Gram, 60 kilograms of azodicarbonamide, 20 kilograms of blowing promotor and 6 kilograms of Methacrylamide, the blowing promotor has following
Structural formula：
Above-mentioned substance is mixed, stirred 5 hours with homogenizer, claret, implantation glass mould is presented to mixture
In die cavity and seal, be placed in 50 DEG C of circulating water chennels and react 72 hours, be subsequently placed in foaming workpiece, together with foaming workpiece
It is placed in electric heating constant-temperature blowing drying box and is foamed, blowing temperature is controlled at 150 DEG C, and foamed time is 25min, is then distinguished
Heat treatment 2 hours is carried out at 160 DEG C and 180 DEG C, the foamed plastics is produced.
Embodiment 2
Foamed plastics is prepared according to the same manner as in Example 1, and difference is without using blowing promotor.
Experimental example
Tensile strength is tested according to GB/T 1040-2006, specimen size is 150mm × 20mm × thickness of slab (8mm), stretching
Speed 5mm/min.On inspection, the tensile strength 73.5Mpa of the sample of embodiment 1, the tensile strength of the sample of embodiment 2
43.5Mpa, is as a result compared, and difference has statistical significance (P ＜ 0.05).As can be seen here, the addition of blowing promotor is significantly
Improve the stretching hardness of product.
