Abstract
The present invention relates to one kind of naturally degradable environment friendly product and its production process. The environment friendly product has calcium carbonate as the main material, easy degradation to become fertilizer, low cost and easy production. It is mixture of calcium carbonate in 50-80 weight portions, starch in 5-25 weight portions, paper pulp in 5-25 weight portions, and sodium cellulose in 2-13 weight portions. It is produced through the following steps: mixing paper pulp, calcium carbonate, water, starch and sodium cellulose inside a kneading and pulping machine;molding the mixture inside a forming mold in a forming extruder; high temperature setting; spraying water repellent; sterilizing in an ultraviolet sterilizing system and packing.
Description
Technical field
But environmentfriendly products that the synthetic materials that the present invention relates to a kind of natural decomposition is made and production technique thereof.
Background technology
Along with the fast development of tourism, fast food, the ready-to-eat industry is also developed rapidly, has driven the heavy demand of disposable food or beverage container and packing box.And the white foamed poly styrene plastic (EPS) that is widely used at present.Because cost is low, health is convenient, and product shaping technology is simple.So occupied most of market of disposable food or beverage container and packaged product.But white expanded plastic has extremely strong chemical stability, utmost point difficult degradation, and used Chlorofluorocarbons (CFCs) (CFC) that there are serious destruction in human immunity system and animals and plants ecotope in process of production, after becoming the food and drink tool, as meeting stripping toxic substance when high temperature uses, infringement human liver and kidney, the difficulty that reclaims after use and handle is big.Burning disposal can produce a large amount of toxic gases, contaminate environment.Just can degrade through the century-old time needing in the buried earth of expanded plastic, but it is to wear out to be cracked into less fragment, sneaks into and forms plate in the soil, has a strong impact on the growth of farm crop, has destroyed the normal use in soil at physical environment.So national departments concerned circulates a notice of to ban use of white expanded plastic already.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point of the prior art, providing a kind of can thoroughly degrade and fuse in soil, compliance with environmental protection requirements, the lime carbonate of main raw material is inexpensive and inexhaustible, becomes argillous fertilizer and free of contamination natural degradation environmentfriendly products after easily degrading and degrading.Another object of the present invention provides the production technique of the natural degradation environmentfriendly products of a kind of high benefit, low cost, shortening production time, technical maturity.
Purpose of the present invention can reach by following measure:
The environmentfriendly products of this natural degradation, its special character is: it is made up of the mixture of following weight proportion, and it is composed as follows:
Lime carbonate 50～80 starch 5～25 paper pulp 5～25 sodium cellulosates 2～13
Wherein, the mixture of optimum weight proportioning is composed as follows:
Lime carbonate 67 starch 15 paper pulp 15 sodium cellulosates 3
Purpose of the present invention can also reach by following measure:
The production technique of this natural degradation environmentfriendly products, its special character are that it comprises following technology:
(1) paper pulp is put into the kneading hollander, put into lime carbonate and an amount of water again, start the kneading hollander raw material is mixed thoroughly;
(2) starch, sodium cellulosate are added the kneading hollander and started, mediate hollander raw material is mixed thoroughly;
(3) will through mediate the uniform synthetic materials of making beating by product required weight put extrusion molding in the formed product mould in the shaping extruder into;
(4) product after moulding is placed on after the taking-up in the set product approval mould of typing flattener, prolongs the compression set type through high temperature;
(5) product takes out through high-temperature shaping oven dry back and delivers to the water-resisting agent spraying machine and make spray treatment, send finished product packing after sending the ultraviolet ray disinfecting system processing again.
Processing step (3), (4) described formed product mould and shaper are made up of upper and lower concave, convex mould with different die temperature; When product prolonged the compression set type at high temperature, shaper had the function of discharging to the gas that is produced in the products material.
Described upper die and lower die are the matching structure of die, punch or punch, die each other.
The present invention has following advantage compared to existing technology:
1, degraded thoroughly, really fused and become fertilizer with soil.
2, reduce the paper pulp consumption, can save a large amount of timber resources.
3, color and luster cleaning is difficult for broken.
4, product is firm, not flexible type.
5, draw materials with low costly, easily accepted by market.
6, working (machining) efficiency height, the time is short.
7, environmental protection does not produce pollution.
Embodiment
The present invention will now be further detailed embodiment:
These environmentfriendly products with natural degradation can be a kind of or its combinations that tableware, cutlery box, drink cup, ashtray or packing are closed.Its prescription is made up of following weight:
Lime carbonate 50～80 starch 5～25 paper pulp 5～25 sodium cellulosates 2～13
Wherein, the mixture of optimum weight proportioning is composed as follows:
Lime carbonate 67 starch 15 paper pulp 15 sodium cellulosates 3
The production technique of this natural degradation environmentfriendly products comprises following technology:
(1) paper pulp is put into the kneading hollander, put into lime carbonate and an amount of water again, start the kneading hollander raw material is mixed thoroughly;
(2) starch, sodium cellulosate are added the kneading hollander and started, mediate hollander raw material is mixed thoroughly;
(3) will through mediate the uniform synthetic materials of making beating by product required weight put extrusion molding in the formed product mould in the shaping extruder into;
(4) product after moulding is placed on after the taking-up in the set product approval mould of typing flattener, prolongs the compression set type through high temperature;
(5) product takes out through high-temperature shaping oven dry back and delivers to the water-resisting agent spraying machine and make spray treatment, send finished product packing after sending the ultraviolet ray disinfecting system processing again.
Processing step (3), (4) described formed product mould and shaper are made up of upper and lower concave, convex mould with different die temperature; Described upper die and lower die are the matching structure of die, punch or punch, die each other.When product prolonged the compression set type at high temperature, shaper had the function of discharging to the gas that is produced in the products material.Described typing flattener has the function to product mold pressurize, time-delay.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
