Abstract
The invention discloses a novel foaming material which is prepared by taking pregelatinized starch as a matrix, adopting an assistant, and using a routine foaming process. As the foaming material takes the pregelatinized starch as the matrix, the pure bio-based foaming material can be completely degraded, has no destruction to the environment, and is nontoxic, odorless and completely environment-friendly.
Description
Technical field
The present invention relates to a kind of foam material, specifically a kind of foam material that can be degradable.
Background technology
Existing foam material, general very difficult plastics of degrading, rubber, the resin etc. of adopting of its basic thing, the non-degradable foam material that is dropped in a large number brings serious pollution to environment.The inventor invents and has studied a kind of Novel foam material that can be degradable thus, satisfies this case and produces thus.
Summary of the invention
The purpose of this invention is to provide a kind of Novel foam material that can be degradable.
To achieve these goals, the present invention adopts following technical scheme:
A kind of Novel foam material, it is equipped with auxiliary agent take pre-gelatinization W-Gum as base-material, is prepared from by conventional foam process.
Above-mentioned auxiliary agent comprises linking agent, whipping agent and dispersion agent, and the weight proportion of above-mentioned base-material and above-mentioned auxiliary agent is:
Above-mentioned auxiliary agent also comprises frothing aid, and the consumption of this frothing aid is the 28-40% of above-mentioned whipping agent weight.
Above-mentioned linking agent adopts peroxide cross-linking agent (DCP).
Above-mentioned whipping agent adopts Cellmic C 121 (AC whipping agent).
Above-mentioned frothing aid adopts zinc oxide or zinc carbonate.
Above-mentioned dispersion agent adopts stearic acid.
After adopting such scheme, Novel foam material of the present invention, take pre-gelatinization W-Gum as base-material, the foam material of this pure bio-based can be degradable, and environment is not produced destruction, and is nonpoisonous and tasteless, fully environmental protection.
Embodiment
A kind of Novel foam material of the present invention, it is equipped with auxiliary agent take pre-gelatinization W-Gum as base-material, is prepared from by conventional foam process.
Particularly, auxiliary agent comprises linking agent, whipping agent and dispersion agent, and the weight proportion of base-material (pre-gelatinization W-Gum) and auxiliary agent is:
In order to strengthen foaming effect, also can add frothing aid, the consumption of this frothing aid is the 28-40% of above-mentioned whipping agent weight.
Wherein, linking agent, whipping agent, dispersion agent and frothing aid can be selected as required, and in the present embodiment, linking agent adopts peroxide cross-linking agent (DCP); Whipping agent adopts Cellmic C 121 (AC whipping agent); Frothing aid adopts zinc oxide or zinc carbonate; Dispersion agent adopts stearic acid.
A kind of Novel foam material of the present invention, take pre-gelatinization W-Gum as base-material, the foam material of this pure bio-based, being embedded in can be degradable after three months in the soil, and environment is not produced destruction, nonpoisonous and tasteless, fully environmental protection.And product has preferably elasticity and physical strength, can satisfy saw, cuts, the various plastic working requirements such as bonding, stamping-out, can be used for the multiple fields such as pantofle, medical treatment product, household articles, food product pack.
A kind of Novel foam material of the present invention is by the technical process realization of batching-mixing-mill packing-slice-weighing-sulfuration-mould unloading cooling-foam sheet.
Particularly, realize as follows:
1, batching: the proportioning according to above-mentioned base-material and each above-mentioned auxiliary agent is prepared burden;
2, mix: adopt Banbury mixer or high-speed kneading machine, each raw material that step 1 is prepared drops in Banbury mixer (high-speed kneading machine) and mixes, temperature is controlled at the 90-100 degree, and basis of time equipment and technology parameter determines that generally and auxiliary agent softening with pre-gelatinization W-Gum mixes get final product fully;
3, mill packing: will put into through the raw material that step 2 mixes and thin bag in the mill, the mill temperature is controlled at the 90-95 degree, and various raw materials are uniformly dispersed, and obtains finely dispersed material;
4, slice weighing: will be pressed into sheet through the finely dispersed material of step 3 packing;
5, sulfuration: the material weighing of the sheet that step 4 is obtained is packed into and is carried out the pressurized, heated sulfuration in the vulcanizer mold, curing temperature 160-180 degree all can, curing time is determined according to mold thickness and temperature, gets final product after the sulfuration mould unloading out cools off.
A kind of Novel foam material of the present invention is also applicable to foam process such as injection foaming, second time of foaming.
Novel foam material of the present invention, it is as follows that property indices detects data:
| Test event | Test value | Unit | Testing method |
