Description
Technical field
The present invention relates to leatherwork technical field, specially a kind of method using the production moulded work of scurf containing chromium.
Background technique
Moulded paper pulp product has light, ventilative, soft and certain intensity, can shield to commodity, shockproof slow
Punching has positioning, measuring body effect, is widely used in food and holds, in the buffer pad of furniture backing plate and other products packaging,
But moulded paper pulp product now is disadvantageous in that its structural strength and cushion performance not as good as foamed plastic, especially tear-proof
Intensity is poor, in transit cracky, since buffering effect is not strong enough, is only applicable to egg tray, the light industrial goods such as mobile phone at present
Liner padded coaming, be unable to satisfy such as household appliances, ceramic tile, stone material and industrial pallet to the higher product of intensity requirement
Pad demand.Therefore, it is necessary to improve the intensity of paper mould paper product and cushion performance to improve its adaptability.
The exploration for improving paper mould intensity is constantly progressive in the prior art, as China Patent Publication No. is
The application for a patent for invention of CN104074105A discloses a kind of intensity that can be effectively improved paper mould paper product and cushion performance
Method for paper pulp molding production is that paper pulp fiber is made in paper pulp raw material crushing, desanding, milled processed, mixed using binder, auxiliary agent
It refines into thickener and paper pulp fiber carries out mixing, and be shaped to paper products using blowing agent injection, this method makes paper mould
The thin wall-type entity structure of product is changed into foaming open grain structure, improves structural strength and cushion performance.But this method
Products obtained therefrom itself still with the hydrophilicity of paper, meets water and is easy to deliquesce destruction.
Tannery is mostly to use chrome tanning by the main tan of skin for blue skin at present, with properties such as toughness, intensity, later
The process such as multiple deburring, shaving, buffing inevitably result from a large amount of chromed leather wastes (also referred to as leather slag, scurf
Deng).These wastes both perplexed tannery due to bringing pollution problem containing chromium, and solution mainly recycles and extracts its collagen
Fiber is to make regeneration leather base cloth；In addition, because it has the characteristics that the toughness of leather and waterproof, if production mould can be applied to
Molding product can then overcome the defect of existing paper products, open up new recycling field, improve waste material use value.
Summary of the invention
The purpose of the present invention is to provide a kind of methods that the latex of scurf containing chromium using wet blue molds, and pass through recycling
Using leather produce in wet blue generated a large amount of scurfs in the processes such as shaving piece is thin be made it is good with fastness, toughness it is good and
It is suitble to the layered product of non-food industries application with anti-hydrolysis property, has the characteristics that low cost, high benefit, can promote development
Circular economy improves resource utilization.
To achieve the above object, the invention provides the following technical scheme: a kind of side using the production moulded work of scurf containing chromium
Method, which comprises the following steps: add water feather plucking to be that fibre stuff is made in fiber the scurf of recycling, be put into storage pool
It is spare；Adhesive is added in storage pool, stirs evenly and skin paste is made；Skin paste is poured into molding die naturally dry to be tentatively formed
Or mold base is shaped to using suction strainer type Pulp forming machine；Mold base after molding is put into molding machine pressurization modeling reality to be shaped to mold
Product；
Each substance is by weight are as follows: 100 parts of scurf, 300~500 parts of water, 6~8 parts of adhesive.
Further, described adhesive is regenerated leather glue special.
Further, described adhesive includes 2~4 parts of synthetic resin, 2~4 parts of aluminum sulfate and 5~8 parts poly- third by weight
Acrylamide.
Further, described adhesive is by weight further include: 3~4 parts of styrene-butadiene latexes, 1~2 part of polyvinyl acetate, 2
~3 parts of polyacrylate, 6~8 parts of starch, 2~4 parts of rosin acids and 2~4 parts of alkyl ketene dimers, 4~6 parts of calcium carbonate, 7
~9 parts of polyurethane.
Further, the moisture content of the mold base is 35%~55%.
Further, the real step of pressurization modeling is specifically to make compacting temperature up to 70~85 DEG C, and compaction pressure is 20~35N,
Compress 2~3s.
Further, further include the steps that moulded work natural cooling.
Compared with prior art, the beneficial effects of the present invention are: the wet blue needs in leather production after chrome tanning are cut out
Trimming and shaving, the wastes such as the leftover pieces and scurf of generation equally have the toughness and intensity of leather, by its feather plucking at fiber
And moulding is hardly damaged so that moulded works, toughness and the intensity such as the protection supporting plate suitable for industrial application is made, and has cushion performance,
The further toughness and intensity that molding is improved using scurf containing chromium and polyacrylamide molecule cross-link makes the more common paper of tool
Product has better tearing toughness and fastness, also has the characteristics that the common paper product such as waterproofness and hydrolysis are unexistent.
Advantages of the present invention is mainly:
1,1300/ ton of recycling valence for comparing the raw material litter decoration of paper products, scurf raw material is almost zero cost, is also solved
The processing puzzlement of leather manufacturer；
2, manufactured skin molding product lear energy, fastness are strong, also have waterproofness, hydrolytic resistance, are not easy to deliquesce damage,
Long product lifecycle adapts to high-intensitive industry carrying；
3, nonflammable compared with paper products, it is not easy to form fire, advantageous production safety.
4, it proposes a kind of new resource reclaim approach, solves the potential pollution sources of leather manufacturer, improve resource benefit
With rate.
