Description
Technical field
The present invention relates to foam material field, more particularly to a kind of biodegradable expanded material and preparation method thereof.
Background technology
Expanded material has high lightweight, specific strength, excellent insulation performance, buffer capacity notable and high adsorption capacity
Advantage, has been widely used in the neck such as auto industry, building industry, packaging industry, agricultural, water process and air filtration
Domain.But at present the overwhelming majority commercialization expanded materials be oil based polyalcohol end prod, such as polystyrene (EPS),
Polyvinyl chloride (PVC), polyurethane (PUR), polyethylene ((PE) etc., these petroleum base polymer foams due to can high temperature resistant,
Acid and alkali-resistance, and with low water absorbable and preferable weatherability, property is stable in natural environment, not degradable, causes serious
White pollution, strong influence is caused to soil, water quality and ecoscape.
The drawbacks of not biodegradable of conventional foams and difficult offal treatment, brings very big to environment
Threat, while raw material it is non-renewable also limit its application and develop.Therefore develop and develop it is a kind of it is new can
Biodegradable expanded material pole is necessary.
The biodegradation material such as starch and lignin is easily by microbial attack, with excellent biodegradability,
Therefore, develop biodegradable expanded material and open a new way not only to better profiting from abundant natural resources
Footpath, also have found effective settling mode for expanded material welding.
The content of the invention
Goal of the invention：In order to solve the problems of in the prior art, the present invention, which is proposed, a kind of is ensureing excellent
It is elastic and it is flexible simultaneously, have excellent biological degradability, the biodegradable expanded material and method of low-carbon environment-friendly concurrently.
Technical scheme：To achieve these objectives, the present invention takes following technical scheme：A kind of biodegradable foaming material
Material, including preparing raw material by weight as follows：Ethylene-vinyl acetate copolymer EVA 10-15Phr, regeneration low-density are high
Pressure polyethylene LDPE 15-20Phr, biodegradation material 50-60Phr, foaming agent 1-3Phr, 0.5~2Phr of zinc oxide, tristearin
0.5~2Phr of acid, peroxide cross-linking agent 0.5-1Phr, calcium carbonate 15-20Phr, colorant 1phr；
The consumption of various raw materials must strictly strict control coordinates in proportion：
The adding proportion of suitable ethylene-vinyl acetate copolymer can improve the pliability of product, elasticity, be excessively added
Cost will be increased.
Regeneration low-density high-pressure polyethylene LDPE suitable addition can improve the cold resistance, heat resistance, wearability of product
And chemical resistance, it is excessively added, product surface can be caused coarse, feel is bad, elasticity reduction.
The effect of foaming agent is the density and hardness for adjusting product.
Zinc oxide is blowing promotor, for adjusting expansion rate, coordinates with the amount of foaming agent and is adjusted, too low, is foamed
The too small waste of dosage of causing to foam of agent gas forming amount, expansion rate slow down, sulfur foam time lengthening, the increased disadvantage of energy consumption
End, crosses at most to foam and causes rate of closed hole to decline soon very much, the problem of product resilience is poor.
Stearic acid is used as helping foaming and lubricant, regulation expansion rate and anti-sticking effect in operating process, foams very little slightly
Slack-off, material slightly sticky equipment in operation then foams slightly accelerate too much, heating of being skidded during mixing is slow, and mill process is in mill
Upper easy roll release.
Peroxide cross-linking agent, suitable addition can adjust crosslink material density；Very few addition can then cause vulcanization to send out
Bubble process middle crosslink density is low, does not live gas so that wrapping so that melt strength is low and forms continuous pore structure or can not foam；Cross
Many additions can then cause sulfur foam process middle crosslink density is too high to cause melt strength too high and expansion ratio is small or can not
Foaming.
Calcium carbonate, as filler, suitable addition can reduce cost, improve foaming nucleation abscess quality；Excessive
Addition can only cause product density height, intensity resilience to be deteriorated, and feel is deteriorated.
It is more highly preferred to, the biodegradation material is thermoplastic starch, polylactic acid PLA and pla-pcl PCL according to 5:
4:1 mass ratio carries out blending extrusion and obtained.
Further, the mesh number of the thermoplastic starch, polylactic acid PLA and pla-pcl PCL is all higher than 200 mesh.
It is more highly preferred to, the foaming agent is azodicarbonamide.
