Abstract
By using crushed crop straw and adhesive as main material and cross linking agent, catalyst and foaming agent as additive, and through mixing, crosslinking, foaming, deposition, stoving to set and natural drying, damping and buffering packing material is produced. The present invention utilizes various crop straw as material to produce packing material at high efficiency and low cost. The packing material is easy to degrade, has good damping and buffering performance, and may be used for package of electric appliance, instrument and other commodity.
Description
The present invention relates to a kind of damping, buffering wrapping material and production method thereof, particularly a kind of usefulness agricultural crop straw and caking agent are as the damping, buffering wrapping material and the production method thereof of raw material.
At present, a large amount of wrapping material that use mostly are porous plastics such as EPS or EPE on the domestic and international market." white pollution " that these wrapping material are serious owing to its non-degradable brings eliminated " white pollution ", but seeks the wrapping material of new natural degradation, become a common research topic of countries in the world.Developed countries such as America and Europe drop into a large amount of funds, research degradable plastics (comprising two types of biological degradation and photodegradation), but mainly be limited to agricultural mulching, yet there are no successful Application on wrapping material.Since 1998, some developed countries forbade that the commodity that have EPS, EPE wrapping material enter its native country; Some country begins to replace EPS, EPE bubble wrap material with paper pulp moulded packaging material.But paper pulp moulding technology uses former carpentery workshop wood pulp, exist waste natural resources, shortcoming such as pulping pollution in early stage, make raw material even adopt to reclaim paper, also still have the manufacturing process complexity, many shortcomings such as efficient is low, cost and energy consumption height and use properties are restricted.In addition, because paper pulp moulded packaging material damping, buffering poor-performing though be useful on smallclothes household electrical appliances, instrument packing at present, also can't be used for packing such as staple commodities such as refrigerator, colour TVs.
The object of the present invention is to provide a kind of packing needs that can satisfy commodity, can reach environmental requirement again, foamed damping, buffering and packing straw fiber material that is easy to degrade and production method thereof.
Technical solution of the present invention is achieved in that and adopts agricultural crop straw crushed material and caking agent as raw material, after technologies such as mixing, crosslinking reaction, foaming, cast, baking typing, seasoning, promptly can be made into the damping, buffering wrapping material.The main component and the weight ratio of damping, buffering wrapping material of the present invention are: agricultural crop straw crushed material 50～70%, caking agent 15～30%, linking agent 5～20%, catalyzer 3～15%, whipping agent 0.5～3%.
The production method of damping, buffering wrapping material of the present invention is:
At first, with pulverizer agricultural crop straw is pulverized, the stalk length after it is pulverized is about 1～10cm, thereafter, manufactures by following processing step:
(1) preparation caking agent by the weight ratio of polyvinyl alcohol, starch and water is: 10～25%: 25～40%: 40～60%, and temperature is controlled between 70～100 ℃ when preparing caking agent; Make postcooling to room temperature;
(2) add agricultural crop straw crushed material and catalyzer in the caking agent for preparing, mixing and stirring adds linking agent and mixes crosslinking reaction 3～8 minutes;
(3) add whipping agent, after fully bubbling, be poured into mold cavity;
(4) mould being sent into temperature is in 60～100 ℃ the drying room, to toast 10～20 minutes, takes out the back demoulding;
(5) product seasoning at normal temperatures is 2～3 days, promptly makes the damping, buffering wrapping material.
Agricultural crop straw of the present invention mainly is meant the mixture of straw, wheat straw, maize straw, sorghum stalks, bagasse etc. or above-mentioned several agricultural crop straws, and described caking agent is the mixture of polyvinyl alcohol, starch and water; Described linking agent is a formaldehyde, and catalyzer is HCl or HNO
3, whipping agent is NaHCO

Advantage of the present invention is:
1. owing to use natural phant such as agricultural crop straw as raw material, caking agent uses water miscible polyvinyl alcohol and starch, and raw material resources are abundant, and comprehensive cost is lower.The product of this invention is easy to degraded after using and discarding, and soil is had improving effect, is the green product of protection environment.
2. linking agent used in the present invention because its consumption is less, and with employed caking agent polyvinyl alcohol, whipping agent NH
4HCO
3Deng reacting, absorb free formaldehyde effectively, thereby can reach state specified standards, can not produce pollution to environment.
3. manufacturing process of the present invention is simple, the production efficiency height, and comprehensive cost is low, and the damping, buffering performance is good, and market application foreground is good.The present invention is expected to substitute EPS, the EPE bubble wrap material that uses in the market, can be widely used in the big or small commodity packagings such as household electrical appliances, instrument, instrument.
Below in conjunction with embodiment the present invention is described in further detail:
1. get polyvinyl alcohol 0.15kg, under 85 ℃ of conditions, be dissolved in the 600mml water, sneak into 0.25kg starch thereafter, make caking agent and be cooled to room temperature;
2. the wheat stalk 3.5kg of weighing length about 1～10cm is mixed evenly with caking agent, adds the catalyzer HCl of 200ml, after stirring, adds 250ml linking agent formaldehyde again, makes it crosslinking reaction about 5 minutes;
3. in above mixture, add whipping agent NH
4HCO
350g after making it fully to foam, pours in the mold cavity;
4. it is 80 ℃ drying room that the mould that will install material is sent into temperature, toasts about 15 minutes backs and takes out the demoulding;
5. with dry at normal temperatures 2～3 days of demoulding product, can obtain proportion was 0.10～0.13g/cm
3, the foam package material of damping, buffering excellent property.
