Description

A kind of high-pressure polyethylene foam material
Technical field
The present invention relates to a kind of foam material, particularly a kind of high-pressure polyethylene foam material.
Background technology
With plurality of raw materials blend such as high-pressure polyethylene, fire retardant, whipping agent, linking agents, through banburying, open refining high magnification that polyethylene hydrocarbon is built bridge by chemistry and foam, and become net high-polymer structure, the product of balanced open cell type bubble.Existing high-pressure polyethylene chemically crosslinked foam material, it not only exists technical recipe complicated, the problem that material cost is high, also exist complex process, blowing temperature not to improve simultaneously, raw material can not thoroughly decompose, environmental hazard factor is large, the problem that labour intensity is large, particularly importantly existing high-pressure polyethylene chemically crosslinked foam material can not be produced continuous coiled material, if need coiled material, will be by sheet material sticky and processing again, so not only can increase labour intensity, waste material has also strengthened cost simultaneously.
Summary of the invention
The object of this invention is to provide a kind of high-pressure polyethylene foam material, there is technical recipe simple, high temperature foaming, raw material can thoroughly decompose, and product is without any peculiar smell, and the feature that elastic properties of materials is good, constancy is good.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
A high-pressure polyethylene foam material, is made by the raw material of following weight part: high-pressure polyethylene 100, Cellmic C 121 5-6, medical stone powder 2.3-2.5, quartz sand powder 40-45, triethyl citrate 3.6-3.8, bamboo charcoal powder 4-6, zinc dialkyl dithiophosphate 2.0-2.5, ferrocene 3-4, zinc oxide 2-3, modified filler 6-8;
Described modified filler is prepared by the following method: the raw material that takes following weight part: attapulgite 110-120, clay 10-12, stalk ashes 50-55, alcohol ester 12 3-4, xitix 2-3, Silane coupling agent KH550 1-2, nano-carbon powder 1-2, sodium bicarbonate 2-3, tributyl citrate 2-3, Sodium Selenite 4-5, cuttlefish bone meal 5-6, dimethyl silicone oil 3-4; Preparation method puts into calcining furnace by attapulgite, clay, at 560-600 ℃, calcines 4-5 hour, takes out, mix with stalk ashes, sodium bicarbonate, cuttlefish bone meal, be ground to and obtain 300-400 order powder, then, then add Silane coupling agent KH550, nano-carbon powder to mix, continue to grind, to fully disperseing, then add other remaining component, continue to grind after 30-45 minute, under 1500-1800 rev/min, stir 15-30 minute, obtain modified filler.
High-pressure polyethylene foam material of the present invention, is prepared from by following concrete steps:
(1) by other each mixing of materials except modified filler, Cellmic C 121, be warming up to 100-120 ℃, mixing 8-12 minute;
(2) material mixing is added modified filler, Cellmic C 121 carry out the mixing 6-10 minute of secondary at 90-100 ℃;
(3) material secondary being mixed hacks, slice, sends in molding device and carries out premolding, and forming pressure is 4-6MPa, and 15-20 takes out after second;
(4) sheet stock is added in the mould of preheating, on vulcanizing press, at 140-160 ℃ of temperature, is forced into 6-7MPa, pressurize 6-12min, removes foam, is cooled to normal temperature and get final product.
High-pressure polyethylene foam material of the present invention, not only formula is simple, and raw material can thoroughly decompose, and product is without any peculiar smell, and product good springiness, and die mould product approval is good and shape highly stablely, and has the advantages such as flame retardant resistance, density are little, light weight, insulation.
