Description

The EVA expanded materials and preparation method of a kind of biomass of blue-green algae containing thermoplasticity
Technical field
The present invention relates to technical field of polymer materials, more particularly, to a kind of EVA hairs of biomass of blue-green algae containing thermoplasticity Foam material and preparation method.
Background technology
Ethylene vinyl acetate (EVA) is the thermoplastic that a class has caoutchouc elasticity.In EVA molecules, due to vinegar The presence of vinyl acetate (VA) construction unit so that the regularity of polyethylene molecule significantly declines, and its crystallinity declines therewith, So that strand ability of inward turning motion in warm-up movement improves a lot, the compliance of strand is improved, and is macroscopically showed It is elasticity very high.EVA can be used to manufacture high magnification separated foam type room temperature expanded material, with good elasticity, density it is light, Flexible resistance is excellent, easy coloring, and the advantages of possess height damping, sound insulation, heat-proof quality, therefore EVA is widely used in motion The fields such as equipment, cushion, children floor, motion footwear material, pad.But general EVA foam shoe material gas permeability, hygroscopicity are poor, When making sole using EVA expanded materials, the sweat secreted by foot's sweat gland can not be evaporated in time, and moist ring is formed in footwear Border, easily grows a large amount of bacteriums, causes foot uncomfortable, influences health, and practicality is low.Additionally, EVA waste products are in natural environment In cannot be decomposed by the microorganisms, cause environmental pollution with environmental protection on problem.Foaming EVA material common in the market is usual Using calcium carbonate as filler, but composite is present, and resilience is poor, compression is larger, and wearability and folding resistance are not Good, the defect such as easily become fragile, crack, and limits its range of application.
With the continuous reduction of resource, pollution it is increasingly serious, people are increased to renewable and circulating resources researchs With exploitation dynamics.It is well known that natural polymer subcategory is various, wide material sources, mainly including cellulose, hemicellulose, wooden Element, shitosan, chitin, starch, protein and natural rubber etc..Filled with the degradable natural such as plant amylum macromolecular and changed The composite that property macromolecular material prepares Partial digestion is paid attention to by countries in the world, the method meet resources conservation, Cost economy, the theory of environmental protection；However, the starch and protein of plant origin, such as cornstarch, soybean protein, are used as For the filler of composite can cause food price to go up, and influence animal feed markets and take more agriculture plantations.
As economy develops the rapid growth with population rapidly, body eutrophication phenomenon is increasingly serious, and freshwater lake is blue Algae wawter bloom phenomenon occurs again and again, and the freshwater lake such as Jiangsu Taihu Lake, Dianchi Lake, Yunnan Province, Chaohu, Anhui Province, China has blue-green algae for several times quick-fried every year Hair, in summer, the blue-green algae for having thousands of tons of daily needs treatment.Blue-green algae contains relatively enriches cellulose, protein, carbohydrate etc. Blue-green algae biomass after natural polymerses, therefore dehydration, drying, deodorization, deodorant can serve as biological based high molecular and answer The filler of condensation material.The Chinese patent of Publication No. CN104479369A discloses a kind of degradation plastic containing algae albumen And preparation method thereof, but the process for extracting algae albumen is cumbersome, and a small amount of protein in microalgae is with only, without filling Divide using other natural polymerses such as the celluloses and carbohydrate contained in microalgae；Additionally, modified algae egg It is white not possess thermoplasticity, it is necessary to adding more plasticizer just prepare algae protein material, with the extension of use time, A certain amount of migration of plasticizer is had, the decline of material property is caused.The Chinese patent of Publication No. CN105001489A is disclosed A kind of bio-based composite polyolefine material and preparation method thereof, after being modified to blue-green algae with acid anhydrides or acyl chlorides, Ran Houyu Polyolefin is blended.But modified blue-green algae needs addition certain in still not possessing thermoplasticity, and composite preparation process The plasticizer of amount.
The content of the invention
Goal of the invention：EVA expanded materials and preparation it is an object of the invention to provide a kind of biomass of blue-green algae containing thermoplasticity Method.Composite foam material prepared by the present invention has that elongation at break is high, resilience is good, tensile strength is big, antibacterial, environmental protection, The features such as ventilative, deodorant, damping.Product of the invention can be widely applied to sports equipment, cushion, children floor, motion footwear material, Pad, the field such as water channel is cursory；And the present invention is to administer blue-green alga bloom, and blue algae resource high-endization application opens one conscientiously Feasible approach.
In order to realize foregoing invention purpose, the present invention is adopted the following technical scheme that：
A kind of EVA expanded materials of the biomass of blue-green algae containing thermoplasticity, it is characterised in that the weight of its key component and each component Measuring number is：15~50 parts of thermoplasticity blue-green algae biomass, 50~85 parts of EVA, 0.5~2.5 part of crosslinking agent, 1~5 part of lubricant, 1~4 part of foaming agent.
Described thermoplasticity blue-green algae biomass are to include being prepared by the key component of following parts by weight：Blue-green algae biomass 100 parts, 50~100 parts of reaction dissolvent, 0.5~5 part of catalyst, 5~20 parts of modifying agent, 50~100 parts of grafted monomers, initiator 1~10 part；Described blue-green algae biomass are one or more blue-green algae in Taihu Lake blue-green algae, Dian Chi blue-green algae, Chaohu Lake Biomass material is obtained by multistage dehydration, drying, deodorization, deodorant；Described modifying agent is 3- isocyanide acid propylenes；Described is anti- It is ethyl acetate to answer solvent；Described catalyst is stannous octoate；Described initiator is potassium peroxydisulfate；Described grafted monomers For methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethyl hexyl acrylate, methyl methacrylate, EMA, One or more in propyl methacrylate and butyl methacrylate.
