Abstract
The invention discloses an improving process for realizing resistance to coffee stain on polyvinyl chloride artificial leather. The process comprises the following steps: uniformly mixing 100 parts of polyvinyl chloride resin, 30-120 parts of an orthophthalic plasticizer with a side chain having 8-10 carbon atoms, 10-30 parts of a polyester plasticizer, 10-80 parts of filler, 2-5 parts of a thermal stabilizer, 3-5 parts of pigment as well as a coffee stain-resistant modified polyurethane material consisting of 1-5 parts of polyurethane resin, 3-10 parts of a solvent, 0.1-0.15 part of an isocyanate bridging agent and 0.01-0.015 part of a promoting agent; feeding the mixture into an internal mixer in sequence for mixing, discharging onto an open rubber mixing machine for plasticizing, rolling into a sheet and jointing with a PVC (Polyvinyl Chloride) rolled substrate; and feeding the rolled and jointed half-finished product into a foaming machine or an embossing machine for heating and embossing, cooling and sizing. By adopting the process, the finished artificial leather has superior coffee stain resistance on the surface.
Description
Technical field
The present invention relates to a kind of artificial leather preparation method, particularly the improvement technique of the anti-coffee stain of a kind of artificial polyvinyl chloride leather.
Background technology
Traditional artificial polyvinyl chloride leather surface is Corvic, its antifouling property is poor, in long-term use procedure, easily pollute on artificial leather surface, especially while allowing the sofa in occasions such as western-style restaurants used for artificial leather, owing to often having coffee spilling out, kaffeeklatsch, to artificial leather padding, causes artificial leather sofa ugly, has to be replaced.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides the improvement technique of the anti-coffee stain of a kind of artificial polyvinyl chloride leather, the improvement technique artificial leather surface simple, that produce of the anti-coffee stain of this artificial polyvinyl chloride leather has the extremely excellent anti-coffee stain effect in surface.
The present invention for the technical scheme that solves its technical problem and adopt is: the improvement technique of the anti-coffee stain of a kind of artificial polyvinyl chloride leather, and concrete steps are as follows:
Step 1: mix: by 100 weight portion Corvics, by the adjacent benzene class plasticizer of 30～120 weight portion side chain C8～C10, 10～30 weight portion polyester plasticizers, the mixed plasticizer of 0～15 weight portion epoxy plasticizer composition, 10～80 weight portion fillers, 2～5 weight portion heat-resisting stabilizing agents, 3～5 weight portion pigment, by 1～5 weight portion polyurethane resin, 3～10 parts by weight solvent, the anti-coffee stain modified polyurethane material of 0.1～0.15 weight portion isocyanates bridging agent and 0.01～0.015 weight portion promoter composition mixes in high speed dispersion mixer, 120 DEG C～130 DEG C of whipping temps, mixing time 180s,
Step 2: calendering formation: by the material mixing enter in banbury, carry out mixing, 130 DEG C～150 DEG C of melting temperatures, mixing time 200～300s, then be expelled on opening rubber mixing machine, plasticate after 15min under the temperature conditions of 120 DEG C～130 DEG C by two opening rubber mixing machines successively, be delivered to and in four-roll calender, be rolled into the sheet material of thickness at 0.5mm ± 0.1mm, then fit with PVC rolled base material, calender operating condition temperature is 165 DEG C～170 DEG C, speed of production is 30 ± 10m/min, laminate pressure >=1T;
Step 3: thermoforming: the semi-finished product after calendering laminating are sent in foaming machine or embossing machine after heating, under hot state, product is carried out to embossing, then can operations for forming condition temperature 180 DEG C～190 DEG C through cooling and shaping.
As a further improvement on the present invention, mixing time 250s in described step 2.
As a further improvement on the present invention, the product cooling and shaping of the method by logical cooling water in knurling rolls after to embossing in step 3.
The invention has the beneficial effects as follows: the present invention adds the anti-coffee stain modified polyurethane material of system in raw material, make artificial leather finished surface there is the extremely excellent anti-coffee stain effect in surface, if coffee-type drink has been infected with on artificial leather surface, just can clean out surperficial spot as long as use common cloth wiping, avoid the infringement that may may cause product surface effect while using cleaning agent cleaning, and in this formula, adopt mixed plasticizer, material is easily processing in process of production, and the artificial leather pliability of production is good.
Detailed description of the invention
Now further describe as follows to technical scheme of the present invention:
Embodiment: the improvement technique of the anti-coffee stain of a kind of artificial polyvinyl chloride leather, concrete steps are as follows:
Step 1: mix:
Mix is prepared burden by scheme in following table:
Wherein:
Filler is at least one in calcium carbonate and magnesium sulfate;
Heat-resisting stabilizing agent is at least one in liquid barium cadmium zinc stabilizer, barium stearate stabilizing agent, cadmium stearate stabilizing agent, zinc stearate stabilizing agent;
Aforementioned batching is all placed in high speed dispersion mixer and is mixed, 120 DEG C～130 DEG C of whipping temps, mixing time 180s;
Step 2: calendering formation: by the material mixing enter in banbury, carry out mixing, 130 DEG C～150 DEG C of melting temperatures, mixing time 200～300s, then be expelled on opening rubber mixing machine, plasticate after 15min under the temperature conditions of 120 DEG C～130 DEG C by two opening rubber mixing machines successively, be delivered to and in four-roll calender, be rolled into the sheet material of thickness at 0.5mm ± 0.1mm, then fit with base cloth, calender operating condition temperature is 165 DEG C～170 DEG C, speed of production is 30 ± 10m/min, laminate pressure >=1T;
Step 3: thermoforming: the semi-finished product after calendering laminating are sent in foaming machine or embossing machine after heating, under hot state, product is carried out to embossing, then can operations for forming condition temperature 180 DEG C～190 DEG C through cooling and shaping.
In formula, use the anti-coffee stain modified polyurethane material being formed by polyurethane resin, solvent, isocyanates bridging agent and promoter, if coffee-type drink has been infected with on artificial leather surface, as long as use common cloth wiping just can clean out surperficial spot, avoid the infringement that may may cause product surface effect while using cleaning agent cleaning.
