Abstract
The present invention relates to a kind of pulullan polysaccharide-inulin base flame retardant type film and preparation method thereof, its component and weight part are: inulin 100 parts, pulullan polysaccharide 20-30 part, red phosphorus 10-20 part, glycerine 10-15 part, palygorskite clay 5-8 part.In the present invention, the combination of inulin and pulullan polysaccharide effectively can improve the intensity of plastics film.
Description
Technical field
the present invention relates to a kind of pulullan polysaccharide-inulin base flame retardant type film and preparation method thereof, belong to macromolecular material and manufacture field thereof.
technical background
petroleum-based plastics, since appearance, with its abundant source, appearance attractive in appearance, health, easy to process, stable in properties and be widely used in a lot of occasion, has become human survival, the indispensable basic material of social development and articles for use.But from Analysis of Environmental Problem, a large amount of discarded plastics, because of its non-biodegradable, bring the puzzlement of white pollution to the living environment of the mankind.Because general-purpose plastics generally wants the centuries just can degrade, long-term hazards is caused to soil, affects crop growth, cause crop production reduction; It is lethal that the plastics be scattered can cause animal to eat by mistake.And degradable native biopolymer is inexhaustible renewable resources, various in style, production cost is low, can not produce pollute environment.But the mechanical property of degradable plastics is poor in prior art, need to improve further.
Summary of the invention
the object of this invention is to provide a kind of pulullan polysaccharide-inulin base flame retardant type film and preparation method thereof, energy
for realizing above object, a kind of pulullan polysaccharide of the present invention-inulin base flame retardant type film, its component and weight part are: inulin 100 parts, pulullan polysaccharide 20-30 part, red phosphorus 10-20 part, glycerine 10-15 part, palygorskite clay 5-8 part.
preferred component and weight part are: inulin 100 parts, pulullan polysaccharide 25 parts, 15 parts, red phosphorus, glycerine 10 parts, palygorskite clay 6 parts.
the preparation method of a kind of pulullan polysaccharide of the present invention-inulin base flame retardant type film is:
(1) be dissolved in acetic acid by pulullan polysaccharide, preparation mass concentration is the pulullan polysaccharide solution of 2%;
(2) add inulin, red phosphorus, palygorskite clay, glycerine, water, be placed in ultrasonic wave separating apparatus and disperse 30min;
(3) at 50 DEG C, gelatinization is carried out, and carry out mechanical stirring, then be poured in mould, dry 20h at 60 DEG C, take off film, be balanced 24-48h in the environment of 70% again in relative humidity, carry out sulfuration, film-making with thermocompressor and chilling press, finally with the injection moulding on injection moulding machine of conventional Shooting Technique.
further, the power of described ultrasonic wave separating apparatus is 600W.
further, described gelatinization time is 20-30min.
the beneficial effect that the present invention produces is that pulullan polysaccharide and inulin have good intermiscibility, the two is combined and namely when reducing glycerine consumption, can improve the intensity of plastics film.To add palygorskite clay be in the film water retention property in order to improve matrix material and reduce costs.The mechanical property that flame-retardant composition red phosphorus does not affect material is added in matrix material proportioning of the present invention.
