Abstract
The invention provides a scheme of a production process of anti-radiation PU (Poly Urethane) synthetic leather. The production process comprises the following specific steps of production process (wet method-dip coating method) and dry-method PU laminating. The wet method-dip coating method comprises the steps that a base fabric (non-woven fabric or kitted fabric) is subjected to blade coating of PU blend paste, then enters a coagulating bath for dipping, is subjected to wet-method film forming and then enters a drying oven for drying. The dry-method PU laminating method comprises the following processing steps of dissolving dry-method PU resin, preparing a mixed solution, coating the mixed solution on a piece of release paper with patterns, drying the release paper by the drying oven and then cooling, coating a layer of bonding layer mixed liquid on the surface of semi-finished leather made by using wet processing, covering the release paper with the mixed solution on the semi-finished product, drying the release paper by the drying oven, and then peeling the release paper to obtain a finished product; and if necessary, conducting the subsequent processes, such as after treatment embossing, cold rolling on the finished product.
Description
Technical field
The present invention relates to for radiation proof synthetic leather field, along with the development of atomic energy industry, a large amount of nuclear radiation lines have infringement to tissue and organ.So in the urgent need to the material that can resist radioactive ray, the pre-radiation proof of past people material commonly used has: lead, lead glass, lead rubber, cement, sandstone, etc. kind, this class materials'use inconvenience is so use is wideless.
Background technology
Many kinds of PU synthetic leather are arranged at present on the market, and its Main Ingredients and Appearance is polyurethane.Along with the development of society, growth in the living standard, the use of PU synthetic leather is also more and more general, and the PU synthetic leather is that drying processes again in the wet dip-coating one deck coating of base cloth.Nuclear radiation is huge to the injury of human body, adds the PU synthetic leather that an amount of radiation proof material composition is made in slurry, can be made into many kinds of radiation proof daily necessitiess with this product, and use is quite general.
Summary of the invention
The invention provides a kind of radiation proof PU synthetic leather production technology, various PU synthetic leather clothings and the articles for use made with this production technology are such as Radiation proof dress, the radiation proof raincoat, radiation-resistant gloves etc. can effectively be kept out nuclear radiation to people's infringement, and the present invention program mainly contains:
1, main raw material and auxiliary agent
1.1 polyurethane, knitted cloth or needle punched non-woven fabrics, thickness 1.0mm, weight per unit area 180～200g/m
2, dimethyl formamide (DMF), aerosol-OT salt, pH value 6.5～7, anionic quickly penetrating agent, sorbitol monooleate (S280), nonionic emulsifier, defoamer CF, cellulose, the raw materials such as smooth agent ACR.
2, production technology (wet method---dip coating)
2.1 technical recipe (parts by mass)
Padding liquid:
Polyurethane resin 320, (S280,10, PU), fast T1 (mill base is some), DMF1000, smooth agent ACR1.
The coating slurry:

1.2.2 process parameter control:
The dipping slurry: about viscosity 400mpa.s, the PU resin solid is divided into 6%～9%.
The coating slurry: about viscosity 2500mpa.s, the PU resin solid is divided into 13%～17%.
Solidification liquid is comprised of DMF and water, and DMF concentration is about 20%.
22 ℃～25 ℃ of setting temperatures, setting time 18min.
1.2.3 process:
Base fabric (nonwoven fabric or knitted cloth) after one PU mixes the slurry blade coating, enters the coagulating basin dipping, and the wet method film forming enters oven for drying again.
1.2.4 the multiple film of dry method PU:
1.2.4.1 technical recipe (parts by mass)
Polyurethane resin=100, DMF350=50, MEK=50, fast T2 (the PU mill base is some)=10, the agent of table place,
1.2.4.2 dry process technique:
With dry method polyurethane PU resin dissolves, behind the preparation mixed solution, be coated in again on the dapple release liners, again after the oven drying cooling, the semi-finished product leather surface that to make through wet-treating applies one deck mixed solution of adhesive layer, at last with the above-mentioned release liners that slurry arranged again in the above, and again through oven for drying, again release liners is peeled off finished product, can carry out next step rear arrangement embossing, the PROCESS FOR TREATMENT finished product such as cold rolling if needed.
