Abstract
The present invention discloses an ethanol tolerance type polyvinyl chloride artificial leather manufacturing method, which comprises: uniformly mixing 100 parts by weight of polyvinyl chloride resin, 30-120 parts by weight of a plasticizer, 30-50 parts by weight of a filler, 2-5 parts by weight of a heat resistance stabilizer, and 3-5 parts by weight of a pigment, discharging the obtained mixture into an internal mixer to mix, carrying out mastication through two open mills, calendaring to obtain a sheet material with a thickness of 0.4-0.6 mm, attaching the sheet material and a PVC calendering substrate, conveying into a foaming machine or an embossing machine to carry out heating, embossing, and cooling shaping, adopting an ethanol tolerance type modified polyurethane to carry out a surface treatment, and drying to obtain the finished product. According to the ethanol tolerance type polyvinyl chloride artificial leather, the ethanol tolerance surface treatment is performed on the surface, such that the surface has an excellent ethanol tolerance function; and when the surface of the produced product requires cleaning by using ethanol, the damage on the surface can not occur, such that the applicability of the product is improved, the service life of the product is prolonged, and the use range is expanded.
Description
Technical field
The present invention relates to a kind of artificial leather preparation method, particularly a kind of ethanol-tolerant type artificial polyvinyl chloride leather manufacture method.
Background technology
Artificial leather product is in long-term use procedure, often need its surface to clean, some spot need to be used alcohol to clean, alcohol is just easy to cause product surface impaired, cause artificial leather damaged surfaces, or artificial leather surface blot is difficult to clean, it is used and cleans to be restricted.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of ethanol-tolerant type artificial polyvinyl chloride leather manufacture method, the artificial leather surface of this ethanol-tolerant type artificial polyvinyl chloride leather manufacture method manufacture has extremely excellent ethanol-tolerant function, use alcohol clean surface can be not impaired yet, improved the applicability of product.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of ethanol-tolerant type artificial polyvinyl chloride leather manufacture method, is characterized in that: concrete steps are as follows:
Step 1: mix:
Corvic 100 weight portions, plasticizer 30～120 weight portions, filler 30～50 weight portions, heat-resisting stabilizing agent 2～5 weight portions, pigment 3～5 weight portions are mixed, wherein 120 ℃～130 ℃ of whipping temps;
Step 2: calendering formation:
By the material mixing in step 1 enter in banbury, carry out mixing, melting temperature is 130 ℃～150 ℃, then be expelled on opening rubber mixing machine, 10min～20 min successively plasticates under the temperature conditions of 120 ℃～130 ℃ by two opening rubber mixing machines, then be delivered in calender and be rolled into the sheet material of thickness at 0.4mm～0.6mm, then fit in traditional PVC rolled base material surface;
Step 3: hot-forming:
Semi-finished product after calendering laminating in step 2 are sent in foaming machine or embossing machine and heated, and heating-up temperature is 180 ℃～190 ℃, and under hot state, product is carried out to embossing, then through cooling and shaping;
Step 4: surface treatment:
On semi-finished product after thermoforming, use ethanol-tolerant modified polyurethane to carry out surface treatment, after drying, complete.
As a further improvement on the present invention, in step 1, batching is carried out mix and blend in high speed dispersion mixer, and mixing time is 180s.
As a further improvement on the present invention, in step 2, mixing time is 250s, and 15min plasticates.
As a further improvement on the present invention, in step 2, calender used is four-roll calender, and four-roll calender processing temperature is 165 ℃～170 ℃, and speed of production is 30m/min, and laminate pressure is not less than 1T.
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.
As a further improvement on the present invention, in step 3, the speed of production of thermoforming is 10m/min.
As a further improvement on the present invention, 130 ℃～150 ℃ of drying conditions in step 4, operating speed 10～20m/min.
The invention has the beneficial effects as follows: the present invention is by carrying out ethanol-tolerant surface treatment on surface, make this product surface there is extremely excellent ethanol-tolerant function, it is clean and while using alcohol that its manufactured goods surface needs, can there is not the impaired situation in surface, improve the applicability of product, extend its service life, expanded its scope of application.
