Abstract
The invention discloses a corn starch degradable plastic film and a preparation method thereof, and relates to the technical field of film preparation. The corn starch degradable plastic film is prepared from the following raw materials in parts by weight: 30-45 parts of corn starch, 20-30 parts of polyvinyl alcohol, 8-12 parts of hydroxy propyl methyl cellulose, 5-15 parts of gelatin, 3-8 parts of carbamide, 5-10 parts of glycerine, 5-10 parts of 35-40% formaldehyde aqueous solution, 10-15 parts of glycerol, and 300-500 parts of deionized water. The corn starch can be conducted by biological degradation, and is abundant in source, inexpensive in price and environmental-friendly; the prepared plastic film is high in intensity, low in cost and biodegradable; white pollution can be relieved effectively.
Description
Technical field:
The present invention relates to thin film fabrication techniques field, be specifically related to a kind of W-Gum degradable plastic film and preparation method thereof.
Background technology:
Flourish along with plastics industry, the environmental pollution that waste plastic film rubbish brings is also on the rise, and white pollution becomes the environmental problem of attracting attention in the whole world.Therefore, people must go into overdrive to develop biological degredation plastic film, administer plastic refuse environment is brought to pollution problem.
Starch is a kind of abundant, cheap natural macromolecular material of originating, also be a kind of inexhaustible renewable resources, it can be biodegradable under multiple envrionment conditions, final degraded product carbonic acid gas and water can pass through the photosynthesis recirculation of plant, can not cause any pollution to environment.Therefore, starch is widely used in research and the product development of degradable plastic film, and has obtained great progress.
Summary of the invention:
Technical problem to be solved by this invention is to provide that a kind of technique is simple, production cost is low and environment amenable W-Gum degradable plastic film and preparation method thereof.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A W-Gum degradable plastic film, by the raw material of following mass fraction, made:
W-Gum 30-45 part, polyvinyl alcohol 20-30 part, Vltra tears 8-12 part, gelatin 5-15 part, urea 3-8 part, glycerol 5-10 part, 35-40% formalin 5-10 part, glycerine 10-15 part, deionized water 300-500 part.
A preparation method for W-Gum degradable plastic film, comprises the steps:
Step a: first take a certain amount of W-Gum, be warming up to 60-70 ℃ after adding deionized water, then add successively polyvinyl alcohol, Vltra tears, gelatin, urea and glycerine by described material rate, stir and make corn starch pasting.
Step b: then add 35-40% formalin and glycerol insulation 15-25min, the solution finally while hot step a being prepared is evenly poured on casting film-forming on the sheet glass of preheating.
The invention has the beneficial effects as follows: W-Gum of the present invention can be biodegradable, source is abundant, cheap, environmentally friendly; And polyvinyl alcohol can be used as tackiness agent and softening agent, effectively promote it with starch between even mixing, improve the mechanical property of film; G & W add the problem that can improve W-Gum indissoluble, infusibility, W-Gum is played to plastification; Plastics film intensity that the present invention makes is high, cost is low and biodegradable, can effectively alleviate white pollution problems.
