Abstract
The invention discloses a preparation method of a plant fiber cushion packaging material. The preparation method comprises the steps of 1) grinding plant fiber, soaking the ground plant fiber in sodium hydroxide for 18-30 hours, filtering and collecting a filter cake, and drying the filter cake; 2) preparing a polyvinyl alcohol solution which is 5-10% in mass concentration, adding the plant fiber dried by the step 1), adding glycerol, sodium bicarbonate, azodicarbonamide and ammonium bicarbonate, and stirring the materials in a stirrer until the materials are completely and uniformly mixed to obtain a mixed sizing material, wherein the mass ratio of the polyvinyl alcohol to the plant fiber to the glycerol to the sodium bicarbonate to the azodicarbonamide to the ammonium bicarbonate is (10-15): (20-30): (3-5): (1-3): (1.2-1.8): (2-6); and 3) adding the mixed sizing agent obtained from the step 2) in a foaming mold and foaming through microwave to obtain the plant fiber cushion packaging material. The prepared foamed material is low in density and high in elastic ratio, and is specifically suitable for cushion packaging.
Description
Technical field
The invention belongs to field of packaging material, be specifically related to a kind of preparation method of Plantfiber buffering package material.
Background technology
Quick and frequent the flowing of resource is the essential characteristic of modern Economy Development, the packing business growing up as flow of resources prerequisite, in industry chain of circular economy, be associated as main low relational degree and low value-added power consumption industry from one with forward direction, develop into gradually one and be associated as the main high added value pollution-free industry with multinomial circulation bind mode and high relational degree with backward.Green Packaging, the environmental pressure minimum producing in life cycle whole process and recycling rate is the highest.Environmentally friendly packing material is the core of Green Packaging, and it can not only reduce and eliminate the pollution to environment, alleviates the pressure to ecotope, and can economize on resources, thereby cause the great attention of countries in the world, and drop into substantial contribution one after another and manpower is developed, obtain at present many important achievement.Amortizing packaging material belongs to that a kind of life cycle is short, the disposable packaging of " used and throw away ", and moment becomes rubbish, apparent to the negative impact of environment.
Using waste paper or crops stalk crushing thing and bonding agent as raw material, after the techniques such as mixing, crosslinking reaction, foaming, casting, baking setting, seasoning, can be made into damping, buffering wrapping material.This material, under low-stress, has good shock-absorbing capacity, and easily degraded, therefore becomes the research emphasis of New Buffering wrapping material.Domestic scholars has been done some researchs for straw amortizing packaging material, but all in the stage at the early-stage, does not still have industrialization product to come out.
Summary of the invention
The object of the invention is to provide a kind of preparation method of Plantfiber buffering package material, vegetable fibre is carried out to alkali immersion treatment, greatly improve foaming effect, microwave foam process is simple, and the time is short, is applicable to large-scale industrial application.
To achieve these goals, the technical solution used in the present invention is: a kind of preparation method of Plantfiber buffering package material, comprises the steps:
1) vegetable fibre is pulverized, added in sodium hydroxide and soak 18 ~ 30h, filter and collect filter cake, dry;
2) polyvinyl alcohol solution that configuration quality concentration is 5 ~ 10%, adds the vegetable fibre after step 1) is dried, and adds subsequently glycerol, sodium bicarbonate, Cellmic C 121, bicarbonate of ammonia, is placed in agitator and is stirred to fully and mixes, and obtains mixed slurry; Wherein polyvinyl alcohol: vegetable fibre: glycerol: sodium bicarbonate: Cellmic C 121: the mass ratio of bicarbonate of ammonia is (10 ~ 15): (20 ~ 30): (3 ~ 5): (1 ~ 3): (1.2 ~ 1.8): (2 ~ 6);
3) by step 2) mixed slurry that obtains is placed in foaming mould, and microwave foaming, makes Plantfiber buffering package material.
Described in step 1), sodium hydroxide mass concentration is 5 ~ 10%, and soak time is 24h.
Step 2) described polyvinyl alcohol solution mass concentration is 10%.
Described in step 3), microwave foaming power is 600 ~ 1200W.
Beneficial effect: the preparation method who the invention provides a kind of Plantfiber buffering package material, oxygen sodium oxide immersion treatment vegetable fibre improves the performances such as expansion ratio, density, elastic specific energy and the residual strain of foam material on can be largely, then foam under microwave with polyvinyl alcohol solution, foamed time is short, frothing percentage is high, the foam material density making is low, and elasticity, than high, is specially adapted to buffering package.
