Abstract
The present invention relates to a high-density hard paper material which can be substituted for wood material in several fields and its forming process. Said process includes the following steps: using various waste and used paper products and plant straw and stalk as raw materials, chri pulverizing, soaking, adding adhesive and water-proof fire-retarding agent, fully grinding to make pulp material by means of grinding machine, then die-pressing and forming. Said invented high-density hard paper material can be used for making various furnitures, series talbewares, decorative materials, handicraft articles and stationary commodities and sports products, etc..
Description
The invention belongs to the daily living article field, relate to and a kind ofly have hard material similar and production technology with wood performance by what paper pulp, adhesive, anti-water fire retardant were formed.
Along with improving constantly of The development in society and economy and living standards of the people, demand to timber-work in the life constantly increases, cause the felling of going to wreck property of extensive forest, just the disposable chopsticks of selling in the market is an example, the annual high-quality timber that will consume ten thousand stere more than 200 has caused the huge wasting of resources and has caused a series of major disasters thus to country.
The objective of the invention is provides a kind of technology simple, with low cost to society, and raw material is extensive, is convenient to draw materials, can be with a kind of new material and the manufacture craft thereof of paper for wood in various fields.
Another object of the present invention is to propose a kind of hard tableware of pulp molding moulding or forming method of food container used.
Realize that technical solution of the present invention is to process many daily living articles by a kind of specific manufacture craft, as furniture, indoor and outdoor decoration material, serial tableware, workmanship, paper pencil etc.The primary raw material of high-density hard paper material material is paper pulp, adhesive and anti-water fire retardant.Wherein paper pulp obtains with the paper products and the processing of plant straw of all kinds of recovery.Adhesive is made with glutinous rice and polyvinyl acetate.Anti-water fire retardant is lead acetate, aluminium chloride and alum, calcium chloride, and they can be used or use separately.The ratio of described paper pulp, adhesive and anti-water fire retardant is: paper pulp 100: glutinous rice 5: polyvinyl acetate 3: anti-water fire retardant 1.85.
Characteristics of the present invention are: material is hard, and plasticity is strong, anti-water, and fire-retardant, cost is low, is easy to machine-shaping, and add different additives and can satisfy different purposes needs, in case damaged, (outdoor) degraded rapidly under field conditions (factors).
High-density hard paper material material manufacture craft of the present invention and products thereof moulding process is introduced with reference to accompanying drawing, may further comprise the steps altogether:
1. making beating: with all kinds of waste and old paper products or plant stalk powder is broken is placed in the pond, soak and fully soaked in 8～10 hours, pull out, press dry moisture.
2. bleaching: will restrain in the clarified solution of bleaching powder wiring solution-formings than 5～7 with per 1,000 ml waters with the paper input of the abundant rinsing of clear water, bleached 3～5 hours, will stir therebetween several times more, pull out and press dry the mobile 10 fens kinds of clear water rinsing of usefulness.
3. essence is floated: as be used to make the high product of hygienic requirements, as the tableware class, also need essence to float, method is: the paper after bleaching through washing, press dry again, soaks 1～3 hour with 5% oxalic acid solution again, pulls out with the clear water rinsing extremely not to be acidity, press dry moisture.
4. high temperature high pressure sterilizing: the paper pulp after the rinsing is put into high-pressure bottle, kept 25～30 minutes down at 120 ℃.
5. the making of glutinous rice adhesive: select for use the high-quality glutinous rice to clean the back and soaked 2～3 hours with clear water, pull out, Steam by water bath is saturating to rotting, can not be half-cooked.Wherein the ratio of rice and water is 5: 8～5: 10.
6. batch mixing: when treating that paper stock is cooled to non-scald on hand, can together drop into fiberizer according to the above ratio with ready made glutinous rice adhesive, anti-water fire retardant, polyvinyl acetate and grind batch mixing, repeated multiple times, mixing, agglomerating to pinching as hard dough sense degree of being with hand.
7. compression molding: batch mixing by the aequum part of making product, is put into the mould extrusion forming, the demoulding (releasing agent can also can use paraffin or grease class with reference to the plastic cement releasing agent).
8. oven dry: molded product is put into 80～100 ℃ of baking oven inner dryings, packing.The disposable tableware class in the polybag of packing into after with film seal, also can adopt case to close packing for keeping its cleaning, health as required, or need not packing, as the sheet material class.
9. process combination: with paper pulp, glutinous rice adhesive, anti-water fire retardant batch mixing high-density hard paper material through compression molding.Cooperate corresponding mould can produce the high-density hard paper product of multiple shape and different purposes by above-mentioned manufacture craft, can make building decorative art work and goods, imitative wooden furniture, workmanship, cultural and sports facility, paper pencil, chess, disposable fast food paper lunch box and disposable toilet paper chopsticks such as class package such as the dish of different shape, box, case, bucket and bowl, chopsticks, cup, dish.
Embodiment:
Present embodiment adopts manufacture craft shown in the Figure of description and the indoor decoration embossing sheet material of producing by extrusion casting apparatus shown in the drawings.
