Description
Technical field
The present invention relates to a kind of leather processing fields, and in particular to a kind of pliability is high, hydrolysis automobile-used artificial leather and
Preparation method.
Background technique
In recent years, with the blowout of Chinese automobile yield, especially middle-to-high end car accounting cumulative year after year, cause user couple
Automobile human-subject test is promoted rapidly, and consequent is that the requirement to automobile is continuously improved.More and more users are no longer only
It is confined to the visual demand to vehicle configuration appearance, the design of automobile interior decoration and its becomes new for user's bring pleasure of the senses
Focus.Interior trim automobile carry user during, be unquestionably with the longest part of user's intimate contact, in addition to base
This decoration function, whether enough comforts can be provided for user, whether can be permanent keep initial color, flower
Whether the designs such as line and sense of touch may generate the use feeling that adverse effect will all directly affect user to user's body health
By.
Therefore, selecting which kind of interior material just seems particularly critical.In very long automobile interior decoration development process, polychlorostyrene second
Alkene (PVC) and polyurethane (PU) material rely on the design color texture expressive force and excellent materialization of its great impact force
The interior material of most mainstream in industry can be become, this also makes its design scheme become the mainstream scheme for substituting corium in industry.But
PVC and PU material causes two kinds of materials to fail to welcome new milestone formula development always since certain defect is individually present.
For PVC material as most widely used at present corium alternative materials, the excellent degree of performance is self-evident.So
And with the continuous improvement that user vehicle requires interior trim comfort, although feel is improved covering with paint scheme and constantly updated, still
It is difficult to meet the needs of user is to product, finds new solution and have become the objective reality that main engine plants have to face.
PU material has the performances such as excellent feel, wear-resisting, resistant to bending, low temperature resistant, but in automobile interior decoration application process, sunlight and temperature
Degree bring light-heat aging and water oxygen effect make PU material itself that hydrolysis phenomena occur.Material will result directly in it once hydrolyzing
Physical property is breached a dyke the falling in of formula.For state-of-the art, the performances such as hydrolysis of PU material are hardly resulted in into one
Step is promoted.
Application for a patent for invention CN108797143A disclose it is a kind of applied to automotive interior section with wear-resisting epidermis
The automobile-used artificial leather of lightweight, the surface treatment agent layer being sequentially distributed from top to bottom, wear-resisting epidermis, foaming layer, glue layer, base fabric
Layer；The wear-resisting epidermis includes: 80-100 parts of PVC resin powder, 50-100 parts of plasticizer, 1-20 parts of heat stabilizer, levelling agent
0.01-20 parts, 0.01-20 parts of antiager, 0.1-30 parts of anti-wear agent, wherein anti-wear agent include: 5-50 parts of hollow glass micropearl,
5-50 parts of hollow ceramic microspheres, adjacent 80-100 parts, 30-90 parts of polyvinyl chloride powder of class plasticizer of benzene.By adding tiny balloon, and
Decentralized processing is carried out to tiny balloon in advance, solves the technical problem that existing PVC artificial leather is not wear-resisting and density is big, is obtained
Not only wearability with higher, but also the PVC artificial leather with lightweight characteristic.But the hydrolytic resistance of automotive interior material
It is the very important factor of user, the problem of the invention application is not concerned with this respect.
Application for a patent for invention CN108642895A discloses a kind of aqueous coating automobile artificial leather and preparation method thereof, presses
According to mass fraction, coating material includes: waterborne, polycarbonate 100, levelling agent 0.5-2, wetting agent 1-3, thickener 1-2, defoaming
Agent 0.2-1, hand feeling agent 0.5-2, silica 0-8；Foaming layer includes: the polyvinyl chloride resin 50-100 of the degree of polymerization 1300, the degree of polymerization
2500 polyvinyl chloride resin 50-100, DINP70-90, stearic acid 0-0.5 is plasticized accelerant A CR0-3, stabilizer 3-5, three oxidations two
Antimony 10-20, foaming agent 3-6, surfactant 0.5-2, calcium carbonate 20-60；Nonfoamed layer includes: the polyvinyl chloride resin 50- of the degree of polymerization 1300
100, polyvinyl chloride resin 50-100, DINP70-90, the stearic acid 0-1 of the degree of polymerization 2500 are plasticized accelerant A CR0-3, stabilizer 3-5,
Antimony oxide 3-10, ultraviolet absorber 0.1-1, antioxidant 0-0.5.Solvent type finishing agent is replaced using aqueous coating agent, is subtracted
Few VOC emission, product have preferable surface color fastness, weather-resistant performance, low temperature resistant cold brittleness, anti-tortuosity and heat-resisting
Property.But the invention application pliability is poor, feel is poor, user experience is poor, meanwhile, material cost is high, so that the cost of vehicle mentions
It is high.
Currently, raising of the user vehicle to automobile human-subject test, causes it to get over the performance requirements such as automobile interior decoration comfort level
Come it is higher, PVC artificial leather feel and in terms of be difficult to meet user demand；And completely new interior design is also right
The performances such as wear-resisting, resistant to bending and low temperature resistant of PVC artificial leather propose requirements at the higher level.To seek more excellent feel, material development
Personnel and interior design teacher apply PU artificial leather in automobile interior decoration, PU artificial leather by splendid feel and pliability by
It greatly promotes, but due to itself group of PU material and molecule segment design reasons, there are hydrolysis problems for the material, hydrolyze bring
Negative effect makes life of product be affected.
