Description
The application is to be the dividing an application of the one Chinese patent application No.200780012416.3 that is entitled as " by ultrared no pressure expansion " on March 27th, 2007 applying date
Technical field
The present invention relates to a kind of method and a kind of device; Be used for grain with a kind of coating, preferred a kind of primer-layer-coated to a kind of leather, particularly ox-hide; The water-based plastic dispersion-s (aqueous plastic dispersion) that will comprise the tight particle (compact particles) that contains a kind of whipping agent is coated on this grain and allows its curing, and forms tiny balloon through heat supply by these tight particles.
Background technology
Known a kind of decoration (dressing) can be provided at the visible surface of leather.Apply a kind of water-based plastic dispersion-s and allow its curing to leather thus through heat supply.Known can the tiny balloon that prepare the mixing with this water-based plastic dispersion-s forms a kind of foamy structure.Existing propose in this water-based plastic dispersion-s, to add tight particle, these particles contain a kind of whipping agent and through in this hardened plastic dispersion-s, exerting pressure and heat forms tiny balloon subsequently by these particles.
Have been proposed in the back side opposite with the visible surface of leather a foam coating is provided, this foam coating is made up of the hardened plastic dispersion-s that contains tiny balloon.Thus; AT 005281U1 has disclosed a kind of leather; The thick foam coating that wherein provides is overleaf formed by a kind of water-based plastic dispersion-s, and this water-based plastic dispersion-s had both contained the tiny balloon for preparing when applying also has tight particle, forms tiny balloon by these particles through heat supply.This thick foam coating has a kind of pooling feature; Open cells (perforate, open cells) and it that it has more than 10% can not be used as undercoat.
AT 006040U1 has disclosed a kind of leather and working method thereof; Wherein opposite with the visible surface of the leather back side provides foam and covers with paint, lacquer, colour wash, etc. (foam finish), and it is through being solidified to form and containing the tiny balloon that the of short duration effect through warm air prepares by a kind of plastic material that applies with liquid form that this foam is covered with paint, lacquer, colour wash, etc.This warm air has the temperature greater than 280 ℃, and therefore a temperature between 350 ℃ and 650 ℃ preferably is very hot and exsiccant, and this has caused in the leather moisture of nature to be suggested and has caused leather to shrink and sclerosis.In addition, because the considerable effect of heat, the tiny balloon of covering with paint, lacquer, colour wash, etc. the superiors zone at this foam often is destroyed.This coating can not be set up further decoration as undercoat equally.
DE 20318311U1 has disclosed a kind of wholegrain face (full-grain) leather; Wherein the defective in this grain layer is revised through a kind of plastic filler; This plastic filler is made up of a kind of hardened plastic dispersion-s, and this dispersion-s contains through heat supply by tight granuloplastic tiny balloon.Tiny balloon is to form through exerting pressure and under at least 100 ℃ temperature, heating.The known generation type of this kind also has shortcoming, and promptly when using desired pressure and temperature, this leather is adversely affected.Yet particularly; Owing to the defective that forms of depression in this forming process not by the plastic filling material completely filled; Because under pressure, having elastic leather to remove the back in pressure solutions recovers; And this plastic filling material does not increase on volume, thus this plastic filling material on its top relatively this leather surface be still depression.Therefore, for reaching a flat fully surface, need the grain layer of this leather is carried out a degree of depth of napping to whole flush, the result is that the quality of this leather has received adverse influence and reduced its value considerably.In addition; When applying acceptable economically pressure and heat; The expand increase of desired temperature of the tight particulate that is used to form tiny balloon does not occur in the lower region of the recess of grain layer, thereby this lower region or do not have only a spot of tiny balloon.Use higher temperature in the sufficiently long time, still this leather is tightr in this zone, to have formed tiny balloon really, and this causes further sclerosis.In addition, subsequently this leather hide is being carried out after rotary drum handles, the characteristic of loose grain is recovered fully, especially in the abdomen area of ox rawhide.
Also attempt being coated with the damage that grey method is repaired grain through so-called.Here, can apply with scraper and a kind of plastisol that often contain the tiny balloon for preparing manually or mechanically is coated on the leather.When dry, material shrink by the ratio of moisture so that fill after depression equally with respect to this grain and recessed, so must carry out napping.
Wherein in the hardened plastic dispersion-s, form those methods of tiny balloon by tight particle, and wherein shortcoming is all arranged, and be inappropriate for the production undercoat through those methods of using very hot air to form tiny balloon by heat and pressure.If use warm air for forming the tiny balloon heat supply; Tiny balloon is formed on the surface of hardened plastic dispersion-s rapidly, but they form a thermal insulation layer herein and stop heat on enough degree, to penetrate darker zone so that form tiny balloon by the tight particle there.Avoid this shortcoming if improve the temperature of warm air, therefore the tiny balloon that on the surface of hardened plastic dispersion-s, has formed just is destroyed, and leather sclerosis and contraction.
DE 24 45 605 C3 have also disclosed the curing that is sprayed onto the plastisol of leather surface by a nozzle; This carries out with the water that evaporates part through the supply heat by an infrared radiator, still forms tiny balloon for the tight particle in the liquid plastisol by being present in this simultaneously.Through these tiny balloons that use ir radiation in this still wet, uncured plastisol, to form caused one very irregular, inhomogeneous and thereby unappealing surface, this surface is studded with tiny balloon and is not suitable for being used for having subsequently as undercoat one to be coated to modify and apply (finish application) especially.
In order to form a coating, be used for applying so far with having the water-based plastic dispersion-s of tight particle that comprises whipping agent that some devices of face have been known in the one side of leather.Here; This coating procedure is to carry out with the shallow layer between 0.015mm and the 0.08mm; This or through cylinder in the direction rotation in the opposite direction of carrying with leather; Perhaps preferably through spraying because the plastisol of low risk viscosity is penetrated in the meticulous depression subsequently on one's own account better and begin to go deep into leather from the surface of leather among.This coating procedure also can carry out by hand, for example through so-called waste pad method.
Summary of the invention
The objective of the invention is to avoid to provide foam coating known leather shortcoming and a kind of leather, particularly ox-hide leather are provided; It has a foam coating at its grain; This foam coating can be produced by the mode of economy; Wherein avoided contraction and sclerosis in the forming process of foam coating, and wherein the defective of leather surface can be eliminated and can not handled by top layer subsequently and damage existing grain structure.In addition; The purpose of this invention is to provide a kind of leather; Wherein eliminated or at least considerable the characteristic that has reduced the loose grain that under soft wholegrain face ox-hide, especially situation, exists all the time in abdomen area; And a undercoat is provided, and this undercoat also tightly adheres to the wholegrain face of this leather and has a surface, on this surface, can apply decorative layer (detailed level without a doubt through any desirable method; Finished layers), these decorative layers have formed for one of this undercoat tight and firm adhesion.
In order to reach this purpose; When being used to according to the method for the invention prepare this kind leather, proposed for the supply that forms the heat of hollow microparticle from tight particle be that to be exposed to wavelength be to carry out the ir radiation between 0.7 μ m and the 100 μ m through containing tight particulate solidified plastisol.Find; This kind ir radiation is being applied to the hardened plastic dispersion-s when (so it no longer contains the water of any significant quantity); Not only heated the surface of plastisol and formation tiny balloon on the surface; And heat also acts on the darker zone of hardened plastic dispersion-s, and the characteristic of leather can not affect adversely and the sclerosis and the contraction of leather can not take place in this heat-processed so that tiny balloon is formed uniformly in total hardened plastic dispersion-s.
To be exposed to wavelength be the dark red external irradiation (dark infrared radiation) between 2 μ m and the 10 μ m if advantageously will contain tight particulate hardened plastic dispersion-s, because therefore guaranteed in the leather the hardened plastic dispersion-s that is used to form tiny balloon at short notice even heating in All Ranges having guaranteed that in such cases heat deeper is penetrated into.According to the present invention, in ir radiation, expose one section and be less than 30 seconds if will contain tight particulate hardened plastic dispersion-s, preferably be less than 20 seconds time length, be exactly enough.
