Abstract
The invention relates to foam plastics. The foam plastics is made of, by weight, 50-150 parts of polycarbonate, 10-20 parts of trigger, 20-50 parts of foaming agent, 10-30 parts of foaming aid, and 1-10 parts of cross-linking agent. The foam plastics has excellent mechanical performance, heat resistance and contour processing, and is an ideal core layer material for engineering structure.
Description
Technical field
The present invention relates to plastic applications, specifically, the present invention relates to a kind of foamed plastic blowing promotor。
Background technology
In order to reduce the weight of plastic product, it is common practice to add foaming agent in the feed, making plastics are formed continuously or discontinuously pore type structure, thus decreasing the use of raw material, reducing raw materials for production cost and product substance。Owing to foaming agent reacts in plastics-production process, pore type structure decreases weight on the one hand so that product becomes slim and graceful, on the other hand, also destroys original compact texture, reduces the structural strength of product, it is necessary to improve in intensity。
Summary of the invention
It is an object of the invention to provide a kind of foamed plastic blowing promotor。
In order to realize the purpose of the present invention, the present invention provides 4-((N-(2-luorobenzyl)-4-(2-fluorophenoxy) benzamido) methyl) benzoic acid purposes in preparing blowing promotor。
Preferably, described blowing promotor can make powder。
Foamed plastic of the present invention has the mechanical performance of excellence, heat resistance and moulding processability, is the desirable core material of engineering structure selection。
Detailed description of the invention
Below by way of the description of detailed description of the invention, the invention will be further described, but this is not limitation of the present invention, those skilled in the art's basic thought according to the present invention, various modifications may be made or improves, but without departing from the basic thought of the present invention, all within the scope of the present invention。
Embodiment 1
Weigh Merlon 80 kilograms, dibenzoyl peroxide 15 kilograms, azodicarbonamide 30 kilograms, 4-((N-(2-luorobenzyl)-4-(2-fluorophenoxy) benzamido) methyl) 20 kilograms of benzoic acid and Methacrylamide 5 kilograms, stir 5 hours with homogenizer, claret is presented to mixture, in implantation glass mould cavity and seal, it is placed in 80 DEG C of circulating water chennels and reacts 36 hours, it is subsequently placed in foaming workpiece, it is placed in electric heating constant-temperature blowing drying box together with foaming workpiece and foams, blowing temperature controls at 120 DEG C, foamed time is 30min, then at 120 DEG C and 150 DEG C, heat treatment is carried out 3 hours respectively, obtain described foamed plastic。
Embodiment 2
Prepare foamed plastic according to the mode identical with embodiment 1, be different in that and do not use 4-((N-(2-luorobenzyl)-4-(2-fluorophenoxy) benzamido) methyl) benzoic acid。
Experimental example
Testing hot strength according to GB/T1040-2006, specimen size is 150mm × 20mm × thickness of slab (8mm), rate of extension 5mm/min。On inspection, the hot strength 61.6Mpa of the sample of embodiment 1, the hot strength 33.3Mpa of the sample of embodiment 2, result compares, and difference has statistical significance (P < 0.05)。As can be seen here, the addition of blowing promotor substantially increases the stretching hardness of product。
Claims (2)
1.4-((N-(2-luorobenzyl)-4-(2-fluorophenoxy) benzamido) methyl) benzoic acid purposes in preparing blowing promotor。
2. purposes according to claim 1, it is characterised in that described blowing promotor can make powder。
