Problems solved by technology
[0002] The surface of traditional polyvinyl chloride artificial leather is polyvinyl chloride resin, which has poor anti-fouling performance. The surface of artificial leather is easy to be polluted during long-term use. Especially when artificial leather is used on sofas in western restaurants and other occasions, coffee is often spilled Will stain the leatherette surface, making the leatherette sofa unsightly and having to be replaced

Embodiment
[0012] Embodiment: a kind of improved technology of polyvinyl chloride artificial leather anti-coffee stain, concrete steps are as follows:
[0013] Step 1: Mix the Ingredients:
[0014] The mixed ingredients are batched according to the scheme in the following table:
[0015]
[0016] in:
[0017] The filler is at least one of calcium carbonate and magnesium sulfate;
[0018] The heat-resistant stabilizer is at least one of liquid barium cadmium zinc stabilizer, barium stearate stabilizer, cadmium stearate stabilizer, and zinc stearate stabilizer;
[0019] Put all the above-mentioned ingredients in a high-speed dispersing mixer and mix evenly, the stirring temperature is 120°C-130°C, and the stirring time is 180s;
[0020] Step 2: Calendering: discharge the uniformly mixed materials into the internal mixer for mixing, the mixing temperature is 130°C-150°C, the mixing time is 200-300s, and then discharged to the open rubber mixer, and then passed through two After the o...

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 [0001] The invention relates to a method for making artificial leather, in particular to an improved technique for preventing coffee stains of polyvinyl chloride artificial leather. Background technique [0002] The surface of traditional polyvinyl chloride artificial leather is polyvinyl chloride resin, which has poor anti-fouling performance. The surface of artificial leather is easy to be polluted during long-term use. Especially when artificial leather is used on sofas in western restaurants and other occasions, coffee is often spilled Will stain the surface of the leatherette, making the leatherette sofa unsightly and having to be replaced. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides an improved process for preventing coffee stains of polyvinyl chloride artificial leather. The improved process for preventing coffee stains of polyvinyl chloride artificial leather is simple, and the ...
