Abstract
A production method of plant fibre foamed packaging material includes the following steps: using bagasse, wheat stem, rice straw, reed and other annual herbaceous plant, etc. as natural plant fibre raw materials, pre-steaming and drying in the sun, grinding and pulverizing boiling and softening pulverized material in autoclove, adding AC foaming agent and additives of starch, etc., mixing and making them into granular material, primary foaming by means of puffing system, then adding water-proofing agent, sodium carboxlate and tribasic alcohol adjuvants, heating in the mould and orientation foaming and puffing so as to obtain the packaging material with required shape. Said new type packaging material can completely be decomposed, does not pollute environment, and can reduce its production cost.
Description
The present invention relates to a kind of manufacture method of plant fiber foaming package material.
" white pollution " that the conventional foam Plastic Packaging Materials is brought is serious, and the main method of the existing degradable foam plastics wrapping material of grasping is to adopt the biological degradation mode and mix photosensitizers accelerated deterioration and cracking process.Because plastic foam material self characteristics, no matter being to adopt biological degradation or photosensitised degradation technology, all can only be to be cracked into the plurality of small blocks fragment, and these fragment foams are thrown aside in the Nature, quicken the deterioration that hardens of soil, still existed the problem of environmental pollution that is difficult to degrade.
The object of the present invention is to provide a kind of manufacture method of plant fiber foaming package material, realized a kind of new packaging material that can decompose free of contamination natural plant fibre foaming fully that adopts, break through the traditional technology of bubble wrap material fully, adapt to world's environmental protection trend.
Task of the present invention adopts following technical scheme to finish: at first natural plant fibre raw materials such as bagasse, straw, straw, reed, annual herb are steamed solarization in earlier stage by material, grind after the oven dry.Raw material after pulverizing is heated in autoclave to 110 ℃-140 ℃, and boiling under the air pressure 2-3 atmospheric pressure is softened, cooking time 30-90 minute; Add additive: AC whipping agent 1-3% (weight percent), starch 15-25% (weight percent) is mixed and made into granularly, is forced into the 4-6 normal atmosphere, and temperature is controlled under 270 ℃ of-290 ℃ of conditions, through expanded system one step foaming, and foamed time 10-25 minute; Add auxiliary agent again: water-resisting agent 7-9% (weight percent), carboxylic acid sodium 1-2% (weight percent), trivalent alcohol 0.1-1% (weight percent), mix back pan feeding mould, heat in mould to 190 ℃-210 ℃, directed foaming is expanded, expanded time 5-15 minute.
The present invention compared with prior art can decompose pollution-freely fully, and it is wide to have a raw material resources, advantage such as production cost is low, and crushing resistance is strong, and shockproof, anti-static effect is good, and performance is better than the bubble wrap material.
The invention will be further described below in conjunction with embodiment:
At first natural plant fibre raw materials such as bagasse, straw, straw, reed, annual herb are steamed solarization in earlier stage by material, grind after the oven dry.Raw material after pulverizing is heated in autoclave to 110 ℃-140 ℃, and boiling under the air pressure 2-3 atmospheric pressure is softened, cooking time 30-90 minute; Add additive: A C whipping agent 1-3% (weight percent), starch 15-25% (weight percent) is mixed and made into granular, be forced into the 4-6 normal atmosphere, temperature is controlled under 270 ℃ of-290 ℃ of conditions, through expanded system one step foaming, and foamed time 10-25 minute; Add auxiliary agent again: water-resisting agent 7-9% (weight percent), carboxylic acid sodium 1-2% (weight percent), trivalent alcohol 0.1-1% (weight percent), pour into after the mixing in the televisor profile packaged die, heat to 190 ℃-210 ℃, directed foaming is expanded, expanded time 5-15 minute.Cool off the back die sinking, promptly get the televisor shock-resistant packaging material of desired shape.
