Abstract
The invention discloses a preparation method of a degradable foam packing material. The preparation method comprises the following steps: 1) rubbing straw to prepare straw fibers; 2) adding 50-54 parts of straw fibers, appropriate amount of water, and 6-8 parts of a plant fiber modifier in a mixer for dispersing uniformly; 3) putting 42-46 parts of corn starch, 6-8 parts of silicon oxide powder, 12-14 parts of talcum powder and 6-8 parts of powdered aluminum into the mixer, heating to 60-70 DEG C, mixing uniformly to prepare a pasty material; 4) adding 200-210 parts of a 4-6% sodium hydroxide solution, and stirring at the same time; 5) coating the wall surface of a mold with 2-4 parts of an organic silicon releasing agent, filling the mold with the mixed slurry, continuously foaming and expanding for 16-18 minutes at the temperature of 125-135 DEGC; 6) drying at 100-110 DEG C to release the mold,so that the finished packing material is obtained.
Description
Technical field
The present invention relates to field of packaging material, relate in particular to a kind of preparation method of degradable foaming wrapping material.
Background technology
Along with the progressively intensification of the understanding of the living environment of the mankind to oneself and influence factor thereof, people's environmental consciousness strengthens rapidly, and more and more stricter restriction has all been taked in the industry of many countries and regions to some damage and pollution ecotopes and the application of product in the world.At present, the buffering package thing of various Industrial products adopts the light weight foam material making of synthetic resins easily mostly in the world, as polystyrene foamed (EPS), polyvinyl chloride (PVC) etc.Due to the non-degradable of these materials, its waste has caused quite serious pollution to environment.The fluorochlorohydrocarbon gas more discharging in its production process due to these materials has caused comparatively serious destruction to the resistance to atmospheric ozone layer with care of the mankind.For many years, people substitute it finding diligently biodegradable light material always.The eighties, people bring into use moulded paper pulp product, attempt the small-sized buffering package thing of Substitute For Partial.Arrive the material that the nineties Chinese patent CN1080301 vegetable fibre is aided with tackiness agent and also attempts to make by suitable foaming EPS foamed glue sample.Japanese Patent JP7017571 attempts to be aided with paper pulp or other vegetable fibres that is similar to paper pulp and to make by foaming with starch the material of EPS foamed glue sample.Above-mentioned materials is except the moulded paper pulp product buffering package for part small-sized (being generally 6kg following) product, and other there is not yet Industrial products and come out.Their existing common issue are: 1, be difficult to make the product thicker, volume is larger; 2, be industrially difficult to find the process means that is suitable for its drying process; 3, product density is larger, generally all at 0.2g/cm
3what have above, also exceedes 0.3g/cm
3, be tens times of EPS foamed glue density even more than 20 times.
Summary of the invention
The object of the invention is to propose a kind of preparation method of degradable foaming wrapping material, wrapping material prepared by the method, take stalk fibre and starch as major ingredient, coordinate appropriate additive and whipping agent, to substitute EPS material, overcome the defect of prior art.
For reaching this object, the present invention by the following technical solutions:
A kind of preparation method of degradable foaming wrapping material, these wrapping material are made up of following component in weight part: stalk fibre 50-54 part, W-Gum 42-46 part, silica powder 6-8 part, talcum powder 12-14 part, vegetable fibre properties-correcting agent 6-8 part, silicone release 2-4 part, aluminium powder 6-8 part, 4-6% sodium hydroxide solution 200-210 part; Described preparation method is:
1) stalk is rubbed to 10-14 minute at vegetable fibre kneading machine, make fiber;
2) stalk fibre, appropriate water, vegetable fibre properties-correcting agent are added in mixing tank and is uniformly dispersed;
3) W-Gum, silica powder, talcum powder and aluminium powder are dropped in mixing tank, be heated to 60-70 ℃, mix, then make pasty state material;
4) add again 4-6% sodium hydroxide solution, stir while adding;
5) mold wall surface is coated with to silicone release, the slurry mixing is packed in mould, be placed at 125-135 ℃ of temperature and continue foaming and intumescing 16-18 minute;
6) demoulding after drying at 100-110 ℃, gets product.
Beneficial effect of the present invention is:
1) the present invention is take stalk fibre and W-Gum as main raw material, and raw material sources are wide and renewable, meet recycling economy requirement.
2) this foam package material quality is light, and outer wall is smooth, the inner closed bubble reticulated structure of hollow that forms, flexible, shock resistance, good heat preservation performance.
3) wrapping material of the present invention are discarded biological degradation voluntarily in physical environment, finally generate CO
2, H
2o and soil ulmin are the ideal substitute of EPS expanded plastic and paper mould material.
