Description
Technical field
The invention belongs to synthetic leather manufacturing field, is related to a kind of manufacture method of PU synthetic leather, and one kind can emboss dry method ring
Protect the manufacture method of sofa artificial leather.
Background technology
Problem of solvent residual (particularly DMF residuals) in traditional solvent-borne synthesis leather goods, is always conventional synthesis leather
Insoluble problem.At present, DMF residual quantities are below 1000mg/kg in leather goods as defined in EU REACH Legislation, and
There is further strict trend.Traditional solvent-borne synthetic leather can not meet this trend, and urgent need finds a kind of effectively reduction
The manufacturing mode of DMF residuals.
Traditional sofa artificial leather coating is typically made up of wet method layer and dry layer, and wherein wet-process coating manufacturing process needs to use
A large amount of DMF (in polyurethane slurry and coagulating bath), ultimately result in a large amount of residuals, account for more than the 90% of whole chemical leather DMF residual.
Coating is thin, and the few dry coating dissolvent residual of solvent load is then than relatively low (typically in below 100mg/kg).Traditional sofa artificial leather is wet
Method coating contains a large amount of micropores, and specific surface area is higher, is easily degraded using process.In order to improve anti-hydrolytic performance, it is necessary to make
With expensive polyether-type or poly- carbon type resin.And dry coating is compact texture, it can be relatively easy to and reach higher
Anti-hydrolytic performance.Therefore, without using wet-process coating, the molten of product can effectively only be reduced using the dry-method chemical leather of dry coating
Agent remains and improved the anti-hydrolytic performance of product.However, conventional dry sofa artificial leather coating is too thin (not having wet-process coating), it is impossible to logical
Cross embossing technique and obtain natural corium lines, of low grade, feel is shrivelled, empty, kishke feel is poor.
The content of the invention
The purpose of the present invention is to propose to the manufacture method that a kind of high physical property can emboss dry method environmental protection sofa artificial leather, product can press
Line, physical property height, hydrolysis, DMF residuals are low, kishke feel is strong, soft.
The manufacture method that this high physical property can emboss dry method environmental protection sofa artificial leather comprises the following steps：
(a) sofa artificial leather base fabric is prepared：A base fabrics and B base fabrics；
(b) A base fabrics are bonded with B base fabrics by adhesive resin, for A base fabrics above, B base fabrics are below, adhesive tree
Added with microballoon foam powder in fat, compound base cloth is obtained after drying foaming；Adhesive formula of size is in mass：
PU resins：100 parts,
Microballoon foam powder：1~40 part,
Solvent：0~100 part,
(c) dried after being coated with surface layer slurry in release liners；
(d) dried after being coated with intermediate layer slurry on the surface layer slurry obtained by c steps；
(e) d step obtained by intermediate layer slurry on be coated with tie layer resins after, be bonded compound base cloth, peeled off after drying from
Type paper, dry method environmental protection sofa artificial leather dry method semi-finished product can be embossed by obtaining high physical property；
(f) emboss, post processing, dry method environmental protection sofa artificial leather finished product can be embossed by obtaining high physical property.
A base fabric counts wherein in step (a) in sofa artificial leather base fabric used are slightly higher；B base fabrics be count slightly
Low, A base fabrics count is 100g/m2~1000g/m2；B base fabrics count is 50g/m2~800g/m2；Step (c) (d)
It is water paste with slurry therewith in step (e).
This high physical property can emboss dry method environmental protection sofa artificial leather, gluing by the way that the sofa leather base cloth of different counts is passed through
Agent resin is bonded, and for the high base fabric of density above, low density base fabric is below, and natural leather density is similar to so as to obtain
The compound base cloth of the institutional framework of gradient.In addition, microballoon foam powder is added with polyurethane adhesive layer, in drying course
By high temperature, gas expansion obtains foam microspheres in microballoon, so as to obtain a thin layer of foaming layer.Applied on compound base cloth
It is furnished with three layers of dry coating.In embossing processes, become by the common melting of gluing oxidant layer, microballoon foaming layer and dry coating
Shape and cooling and shaping effect, the lines on dandy roll has clearly just been fixed on into high physical property can emboss dry method environmental protection sofa artificial leather
On.This high physical property can emboss dry method environmental protection sofa artificial leather and not contain wet-process coating, even if using solvent type polyurethane resin, DMF
Residual can be in below 100mg/kg；Using aqueous polyurethane, then DMF residuals are 0.In addition, product anti-hydrolytic performance is preferable, clump
Woods, which is tested, peels off conservation rate for 5 weeks up to more than 85%；After embossed, surface pattern is clear, naturally, product feel is soft
It is soft, kishke feel is strong.
