Abstract
The invention relates to a preparation method of expanded plastic. The method comprises the following steps: 80 kg of polycarbonate, 15 kg of dibenzoyl peroxide, 30 kg of azodicarbonamide, 20 kg of 4-(( N-( 2-fluorobenzyl)-4-(2-fluorophenoxy) benzoylamino)methyl) benzoic acid and 5 kg of methacrylamide are weighed and stirred by a high-speed stirring machine for 5 h until a mixture is wine red, the mixture is injected into a cavity of a glass mold and sealed, the mold is placed in a circulating water channel at the temperature of 80 DEG C for a reaction for 36 h, then a product is placed in a foaming tool, the product and the foaming tool are arranged in an electric heating constant-temperature air drying oven for foaming, the foaming temperature is controlled at the temperature of 120 DEG C, foaming is performed for 30 min, then a foamed product is subjected to heat treatment for 3 h at the temperature of 120 DEG C and subjected to heat treatment for 3 h at the temperature of 150 DEG C, and a final product is obtained.
Description
Technical field
The present invention relates to plastic applications, specifically, the present invention relates to the system of a kind of foamed plastic
Preparation Method.
Background technology
In order to reduce the weight of plastic product, it is common practice to add foaming agent in the feed,
Make plastics are formed continuously or discontinuously pore type structure, thus decrease the use of raw material, fall
Low raw materials for production cost and product substance.Owing to foaming agent is to rise during plastics-production instead
Answering, on the one hand pore type structure decreases weight so that product becomes slim and graceful, on the other hand,
Also destroy original compact texture, reduce the structural strength of product, need in terms of intensity
Improve.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of foamed plastic.
In order to realize the purpose of the present invention, the present invention provides the preparation method of a kind of foamed plastic,
The method comprise the following steps: to 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,
Present claret to mixture, in implantation glass mould cavity and seal, be placed in 80 DEG C of recirculated waters
Groove reacts 36 hours, is subsequently placed in foaming workpiece, is placed in electric heating together with foaming workpiece
Foaming in constant temperature blast drying oven, blowing temperature controls at 120 DEG C, and foamed time is 30
Min, carries out heat treatment 3 hours the most respectively at 120 DEG C and 150 DEG C, obtains described foaming and moulds
Material.
Foamed plastic of the present invention has mechanical performance, heat resistance and the molding of excellence and adds
Work performance, is the preferable 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
Being limitation of the present invention, those skilled in the art, according to the basic thought of the present invention, can do
Go out various amendment or improvement, but without departing from the basic thought of the present invention, all in the present invention
Within the scope of.
Embodiment 1
Weigh Merlon 80 kilograms, dibenzoyl peroxide 15 kilograms, azodicarbonamide
30 kilograms, 4-((N-(2-luorobenzyl)-4-(2-fluorophenoxy) benzamido) methyl) benzoic acid 20
Kilogram and Methacrylamide 5 kilograms, with homogenizer stir 5 hours, to mixture in
Existing claret, in implantation glass mould cavity and seal, is placed in 80 DEG C of circulating water chennels reaction
36 hours, it is subsequently placed in foaming workpiece, is placed in electric heating constant temperature drum together with foaming workpiece
Foaming in wind drying baker, blowing temperature controls at 120 DEG C, and foamed time is 30min,
At 120 DEG C and 150 DEG C, carry out heat treatment 3 hours the most respectively, obtain described foamed plastic.
Embodiment 2
Preparing foamed plastic according to the same manner as in Example 1, difference is not use
4-((N-(2-luorobenzyl)-4-(2-fluorophenoxy) benzamido) methyl) benzoic acid.
Experimental example
According to GB/T1040-2006 test hot strength, specimen size be 150mm × 20mm ×
Thickness of slab (8mm), rate of extension 5mm/min.On inspection, the stretching of the sample of embodiment 1 is strong
Degree 61.6Mpa, hot strength 33.3Mpa of the sample of embodiment 2, result compares,
Difference has statistical significance (P < 0.05).As can be seen here, the addition of blowing promotor carries significantly
The high stretching hardness of product.
