The degradable natural and environment-friendly raw materials are utilized for preparing plastic, cost is low, the preparing method is simple, products are easy to decompose, and the thermoplastic is beneficial for industrial production.
Description
Technical field
The present invention relates to technical field of polymer materials, especially relating to a kind of take algae as thermoplastics prepared by main raw material.
Background technology
Plastics oneself be widely used in each department of national economy, this is mainly because it has the advantages such as lightweight, satisfactory mechanical property, water-fast resistance to chemical attack, good looking appearance, making and installation be convenient and cheap; According to statistics, nearly 100,000,000 tons of the plastics ultimate production in the annual world, this accounts for greatly more than 75% of three large synthetic materials total amounts, reaches 92% with the volumetric production ratio of iron and steel.But the chemical stability of conventional plastic is fine, almost can not be degraded at occurring in nature, when plastics industry to a certain extent time, abandoned plastic garbage is just more and more, has almost arrived the degree be seen everywhere, therefore, the hidden danger that plastics itself exist comes out gradually; Such as in China; non-returnable container plastic material is as in 1/3; the annual plastic garbage just having more than 70 ten thousand tons produces; simultaneously; owing to lacking effective taking back and process system, relevant special management regulation and economic policy, " white pollution " is caused to become international environment protection and social concern.
Widely using and discarding of conventional petroleum based high molecular material, not only causes petroleum resources seriously deficient, but also causes the bed of nails that " white pollution " increasingly sharpens.Be subject to the attention of countries in the world with the matrix material that the filling-modified Polymer materialspreparation of the degradation materials such as plant amylum obtains Partial digestion, the method meets the theory of resources conservation, economical, environment protection; But the starch of plant origin, as W-Gum, the weighting agent being used as matrix material can cause food price to go up, and affects animal feed markets and take more agriculture plantation.
In recent years, along with the quick growth of economy and population, body eutrophication phenomenon is day by day serious, and blue-green alga bloom phenomenon occurs again and again, and blue-green algae problem has become the important subject of lake basin.When Blue-green Algae Fast Growth, directly salvaging blue-green algae is slow down outburst degree, protection water ecological setting the most directly and safely and effectively Emergency management method.According to statistics, during Taihu Lake blue algae blooms in 2011, the blue-green algae salvaging amount of every day reaches 3000 tons, and the annual blue-green algae of salvaging altogether amount is 970,000 tons.Except Taihu Lake, Dian Chi, Chaohu also have blue algae bloom for several times every year, have every day the blue-green algae of thousands of tons of to need process.The blue-green algae of salvaging disembarkation can take a large amount of soils and stack, and stacking blue-green algae generation percolate will form secondary pollution by osmosis, storm runoff etc.Therefore the blue-green algae dealt carefully with after salvaging seems particularly important.
Blue-green algae is rich in more rich nutritive ingredient (protein, fat, carbohydrate etc.), therefore can as the potential novel biomass resource of a kind of tool.At present, the recycling of bloom blue algae mainly concentrates on as aspects such as bioenergy, bio-feritlizer, microorganism culturing raw material and biologically active substance extractions.Be detect cyanophycean toxin, from the utilization limiting its nutritive ingredient in the health-related food of raw material with blue-green algae at some.
Summary of the invention
For the problems referred to above that prior art exists, the applicant provides thermoplastics prepared by a kind of algae.The present invention utilizes degradable natural green material to prepare plastics, and cost is low, and preparation method is simple, and product easily decomposes, and is conducive to suitability for industrialized production.
Technical scheme of the present invention is as follows:

Described plasticizer additives comprises 50 ~ 70wt% biodegradable polymer, 10 ~ 30wt% native thermoplastic raw material and 5 ~ 20wt% expanding material.Described biodegradable polymer comprises poly(lactic acid), poly-hydroxy methane, poly-3-hydroxybutyrate, the multipolymer of 3-hydroxybutyrate and 3-hydroxypentanoic acid, the multipolymer of 3-hydroxybutyrate and 4 hydroxybutyric acid, the multipolymer of 3-hydroxybutyrate and diethoxalic acid, the multipolymer of 3-hydroxybutyrate and 3-caproic acid, at least one in the multipolymer of 3-hydroxybutyrate and 3-Hydroxyoctanoic acid.Described native thermoplastic's raw material comprises at least one in thermoplastic starch, thermoplastic vegetable protein matter.Described thermoplastic vegetable protein matter comprises zein, maize gluten, glutenin, mustard caul-fat, sunflower, Chinese sorghum, chorista soybean protein, at least one concentrated in body soybean protein, all albumen flour.
Described plasticizer additives also comprises 5 ~ 10% polyolefine.Described polyolefine comprises at least one in the multipolymer of polyethylene, polypropylene, ethene and propylene, polyethylene-co-vinyl acetate.
Described algae through removing impurity, oven dry, process of lapping, uses after crossing 200 ~ 500 mesh sieves before use.
The technique effect that the present invention is useful is:
Method of the present invention can reduce the use of non-degradable petroleum-based plastics, economizes on resources; Also for annual algal tufa burst period proposes the treatment process that a kind of algae changes harmful to treasure, protection of the environment is conducive to.Degradable plastics containing algae albumen of the present invention, low production cost, technique is simple, and has good mobility, is suitable for mold pressing, extrudes and injection molding, can be widely used in the process for processing fields such as food, agricultural, packaging and environmental protection.Degradable plastics containing algae albumen of the present invention, can be decomposed by the microorganisms completely in soil, environmentally safe, degradation production can be used as fertilizer.
