Abstract
The completely degradable buffering package lining material can be degraded fast and naturally without producing pollutant, and has light weight, good foaming performance and different colors. It is prepared with modified starch, natural fiber, CaCO3, natural fatty acid, water and dye in certain weight proportion. The preparation process includes crushing material, mixing to form slurry, injecting the slurry into mold, punching at 160-210 deg.c for 15-20 sec, demolding, and drying to settle. The present invention is used in packing product with complicated structure and in making disposable tableware.
Description
Technical field:
The present invention relates to a kind of buffering package lining box material and preparation method thereof.Particularly a kind of high-fall buffering package lining box material and preparation method thereof of separating.
Background technology:
For baroque fragile product or electric equipment products, such as glasswork, mobile phone, precision instrument and various electrical equipment or the like run into sharp impacts in transit, jolt, be damaged easily, therefore for the safety of product in guaranteeing to transport, must add buffering package lining box, in order to damping vibration with jolt to the destruction of product in the product outside.
Present buffering package lining box adopts the expanded plastic injection moulding more, or molded with wood pulp, can reach damping vibration and jolt to the effect of product destructive.But, when packing materials that expanded plastic abandons as dismounting, because its non-degradable is seriously polluting environment.And the raw material that the wood pulp film is moulded is a timber, derives from natural trees, and the natural resources of trees is very limited, and very valuable, moreover the production process of wood pulp is the process of serious environment pollution.
Publication number is CN1236725A (1999), and denomination of invention is the patent of " Disposable chopsticks of plant fiber and food product containers and production method thereof ", discloses each component and weight is respectively; Starch 20-40%, vegetable fibre 20-40%, salt 1-3%, aminoresin 10-30%, lime carbonate 4-8%, water 5-15% is used for to the technical scheme of making throwaway chopsticks and food product containers.The enforcement of this technical scheme needs a large amount of vegetable fibres, and causes complex manufacturing technology and cost to increase.
Publication number is 1117977A (1996), denomination of invention is the patent of " biodegradable plastic and manufacture method thereof ", disclose the technical scheme of main component for poly-trisaccharide maltose macromolecular compound, the raw material cost that this technical scheme is used is higher and be difficult to acquisition, makes the price of goods higher.
Publication number is CN1371944 (2002), denomination of invention is the patent of " a kind of Wholly-degradable material and utilize this material to make the method for disposable product ", disclose in its component amino film plastics and be the technical scheme more than 35%, the degradation condition of its goods is higher, and the degraded difficulty strengthens.Film formation time is longer simultaneously, and needs film forming in 50 second influences production efficiency.
Publication number is 1196658A (1998), denomination of invention is in the technical scheme of " preparing the method that degradable thin-walled film is moulded thing " patent, owing in the production process, need the pH value of control material to be processed, cause complex process, and the difficulty of the pva degradation in the component is bigger.
Summary of the invention:
The present invention aims to provide a kind of degradable packing lining box material and preparation method thereof.It is all made with biological composition, can rapid and natural degrade at nature, does not produce the waste gas of contaminate environment, refuse; Goods in light weight foams, and has different colours, can satisfy human consumer's personalized requirement.
The present invention includes following each component according to weight ratio:
Treated starch 30～34%
Natural fiber 3～8%
CaCO3 1～2％
Natural acid 0.3～1%
Water 40～60%
Natural toner 0.05～0.5%
Will be according to the treated starch 30～34% of weight ratio, natural fiber 3～8%, CaCO3 1～2%, and natural acid 0.3～1% is fully pulverized, and stirs and adds 50～60% water, and thorough mixing stirs pulping.Paste mixture is injected mould, under 160～210 ℃ of temperature, take out the package lining base after the die sinking in 15～20 seconds of punching press, the package lining base promptly becomes product of the present invention through the drying of finalizing the design.
Wherein, treated starch can be the modified corn starch of dry production, modified potato starch, the mixture of modified tapioca starch or these three kinds of treated starches.
The typing drying can be to place infrared-ray dryer to dry the package lining base.
Goods of the present invention are used for the buffering package lining box of baroque fragile product or electric equipment products, because making method of the present invention employing is molded, can be identical closely with packed article, and structurally guaranteed shock-absorbing function.Owing to add relatively large water in the component of the present invention, make goods under the state of pressurized, heated, produce competent water vapour, impel foaming fully, make its material not only have good bumper and absorbing shock performance, and proportion is little, under the equal volume, in light weight, reduced the burden of transporting.Product surface of the present invention is smooth, and the demoulding is easy, because the intermiscibility of each component and pigment can add various pigment in product, makes product color abundant, satisfies variant production and user's requirement.
Because component of the present invention is all made with biological composition, when it becomes packaging waste, in the very fast degraded of nature, does not need special degradation condition, does not produce waste gas, the waste water of environmental pollution during degraded.
Because component of the present invention is nontoxic, harmless biological composition, and the product after the moulding has the build molecular structure, has certain leakproof and anti-permeability, therefore, also is the preferred material of making disposable table ware.
In sum, a kind of degradable packing lining of the present invention box material and preparation method thereof.It is all made with biological composition, can rapid and natural degrade at nature, does not produce the waste gas of contaminate environment, refuse; Goods in light weight foams, and has different colours, can satisfy human consumer's personalized requirement.
