Abstract
The invention discloses a lightweight inorganic filled low-density polyvinyl chloride artificial leather making method. The method comprises the following steps: uniformly mixing 100 parts of polyvinyl chloride resin, 0-80 parts of an o-phenyl plasticizer, 0-30 parts of an m-phenyl plasticizer, 30-100 parts of a p-phenyl plasticizer, 5-60 parts of a hollow inorganic filler with the density being lower than that of the polyvinyl chloride resin, 2-5 parts of a stabilizer and 3-5 parts of a pigment; sequentially injecting the above obtained mixture into an internal mixer, mixing, discharging the mixed mixture to an open rubber mixing machine, plasticizing, calendering to form a sheet, and laminating the sheet to a base cloth; and sending the obtained calendered and laminated semi-finished product into a foaming machine, heating, foaming or embossing, and carrying out cooling setting. The low-density hollow inorganic filler added in the invention effectively reduces the density of artificial leather, reduces the weight of artificial leather with same thickness, and realizes lightweight of products; and the interface strength of the mixture is greater than that of traditional polyvinyl chloride/calcium carbonate systems, so superlight high-strength artificial leather is realized.
Description
Technical field
The present invention relates to a kind of artificial leather preparation method, particularly a kind of light-weight inorganic fills low density polyvinyl-chloride artificial leather manufacture method.
Background technology
At the artificial leather that some special occasions use, as ultralight running shoes etc., need material to try one's best lightweight, artificial leather density conventional is at present high, and quality weight, cannot meet ultralight demand.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of light-weight inorganic and fill low density polyvinyl-chloride artificial leather manufacture method, the artificial leather that the method is produced has the feature of light-high-strength.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of light-weight inorganic fills low density polyvinyl-chloride artificial leather manufacture method, and concrete steps are as follows:
Step one: mix: 100 weight portion Corvics, the mixed plasticizer be made up of benzene class plasticizer 0 ~ 80 weight portion o-benzene plasticiser, 0 ~ 30 weight portion inclined benzene class plasticizer and 30 ~ 100 weight portions, 5 ~ 60 weight portion density are placed in high speed dispersion mixer lower than the Hollow Inorganic filler of Corvic, 2 ~ 5 weight portion stabilizing agents and 3 ~ 5 weight portion pigment and mix, whipping temp 110 DEG C ~ 130 DEG C, mixing time 100 ~ 200s;
Step 2: calendering formation: the material mixed is entered carry out in banbury mixing, melting temperature 130 DEG C ~ 160 DEG C, mixing time 200 ~ 300s, then be expelled on opening rubber mixing machine, carry out plasticating after 15min under the temperature conditions of 120 DEG C ~ 130 DEG C by two opening rubber mixing machines successively, be delivered in four-roll calender and be rolled into the sheet material of thickness at 0.4mm ± 0.1mm, then carry out fitting with base cloth, calender operating condition temperature is 160 DEG C ~ 180 DEG C, speed of production is 30 ± 10m/min, laminate pressure >=1T;
Step 3: foaming embossing: after the semi-finished product after calender lamination are sent into foaming machine foamable, under the state of heat, product is foamed or embossing, then through cooling and shaping, foaming machine operating condition temperature 190 DEG C ~ 200 DEG C.
As a further improvement on the present invention, step one hollow core inorganic filler is hollow glass ball.
As a further improvement on the present invention, described hollow glass ball comprises 0 ~ 30 weight portion diameter be 10 μm ~ 50 μm hollow glass balls and 0 ~ 30 weight portion diameter is 50 μm ~ 100 μm hollow glass balls.
As a further improvement on the present invention, the method for logical cooling water in knurling rolls is passed through in step 3 to the product cooling and shaping after embossing.
The invention has the beneficial effects as follows: in the present invention, with the addition of low-density Hollow Inorganic filler, effectively reduce the density of artificial leather, the artificial leather quality of condition of equivalent thickness is alleviated, achieve the lightweight of product, and the boundary strength of mixture is greater than traditional polyvinyl-chloride/calcium carbonate system, achieves ultralight High-strength artificial leather.
Detailed description of the invention
Now further describe as follows to technical scheme of the present invention:
Embodiment: a kind of light-weight inorganic fills low density polyvinyl-chloride artificial leather manufacture method, and concrete steps are as follows:
Step one: mix:
Mix is prepared burden by scheme in following table:
Wherein:
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 mixes, whipping temp 110 DEG C ~ 130 DEG C, mixing time 100 ~ 200s;
Step 2: calendering formation: the material mixed is entered carry out in banbury mixing, melting temperature 130 DEG C ~ 160 DEG C, mixing time 200 ~ 500s, then be expelled on opening rubber mixing machine, carry out plasticating after 15min under the temperature conditions of 120 DEG C ~ 140 DEG C by two opening rubber mixing machines successively, be delivered in four-roll calender and be rolled into the sheet material of thickness at 0.4mm ± 0.1mm, then carry out fitting with base cloth, calender operating condition temperature is 160 DEG C ~ 180 DEG C, speed of production is 30 ± 10m/min, laminate pressure >=1T;
Step 3: foaming embossing: after the semi-finished product after calender lamination are sent into foaming machine foamable, under the state of heat, product is foamed or embossing, then through cooling and shaping, foaming machine operating condition temperature 190 DEG C ~ 200 DEG C.
By leading to the method for cooling water to the product cooling and shaping after embossing in knurling rolls in step 3, the method cooling velocity is fast, and cooling evenly.
The mixed plasticizer be made up of polymeric plasticizer, adjacent benzene class plasticizer, partially benzene class plasticizer and sulphonic acids plasticizer, the molecular weight of this kind of mixed plasticizer is very large, strand is very long, it is the large molecule plasticizer close to even exceeding polyvinyl chloride average degree of polymerization, merge with effective winding of polyvinyl chloride molecule agglomerate owing to enhancing, effectively can resist solvent to the extraction of polymeric material damage and corrosion, avoid artificial leather to meet solvent and damage, prolonged human fabricate-leather service life.
