Description
Technical field
The invention belongs to PVC artificial leather technical field, particularly one is used for PVC artificial leather surface-treated aqueous treatment agent and preparation method thereof.
Background technology
The structure of leather is imitated in the exploitation of initial artificial leather and synthetic leather, the substitute material of exploitation leather, with solve leather produce in the not enough and problem of environmental pollution of raw material.Wherein artificial leather is the leather substitute material grown up the earliest, up to the present still in artificial leather synthetic leather industry, occupies half of the country.According to State Statistics Bureau's statistics, artificial leather synthetic leather national output in 2010 is 2,140,000 tons, within 2011, reaches 2,410,000 tons, its production rank the first in the world.Wherein PVC artificial leather output accounts for more than 40%.
PVC artificial leather forms coating agent by Corvic (PVC), plasticizer, stabilizing agent, blowing agent etc., by different production technologies, and a kind of simulated leather material that blade coating or laminating are made on base cloth.Concrete production technology has direct knife coating, blade coating foaming, the transfer coated method of release liners, transfer coated of steel band, rolling process and extrudes laminating method and extruding and hot melting method etc.
There is the artificial leather of substrate to be PVC paste be coated on cloth or on paper, then plastify more than 100 DEG C and form.Also first PVC and auxiliary agent can be rolled into film, then form with substrate pressing.The artificial leather at the linerless end is then directly be rolled into certain thickness soft thin slice by calender, compresses decorative pattern.Artificial leather can be used for making the cushion etc. of leather trunk, suitcase, the front cover of book, sofa and automobile, also has plastic floor leather, as the pavement of building.
PVC artificial leather is in production process; the artificial leather surface that plasticizing forming obtains is shinny; have and very strong mould sense; in order to make the outward appearance of PVC artificial leather and feel more close to corium; usually can add lustre to its surface, delustring and improve the surface treatment of feel, to obtain the feel of soft gloss and similar natural leather.
And use more PVC artificial leather surface conditioning agent mostly to be solvent-based system at present, one is produced per year to the factory of 1,800 ten thousand tons of PVC artificial leather, it is annual because consumption 7500 tons of solvents are comprehended in surface, and the Water spray rate of recovery of routine only has 90%, the organic solvent be discharged in air has very large harm to human body and environment, and solvent residual meeting in the product simultaneously causes product safety problem.
In order to solve the problem, exploitation is used for the main path that PVC artificial leather surface-treated aqueous treatment agent is current technological development with replace solvents type finishing agent, product is based on aqueous polyurethane, but still there is following problem: one, main component due to PVC artificial leather is polyvinyl chloride resin and plasticizer, after plasticizing forming, water-base resin is difficult to sprawl on the surface of PVC artificial leather, that is levelability is bad, particularly for deep-treaded product, be difficult to process decorative pattern rill depths, be difficult to meet product requirement; Its two, water-base resin is very poor at the bond properties on the surface of PVC artificial leather, after causing water-base resin film forming, very low in the peel strength of PVC surface, is difficult to meet product requirement.
Summary of the invention
