Embodiment 1

[0025] An environmentally friendly, wear-resistant and degradable PVC decorative artificial leather, made of the following raw materials: 135 parts of PVC resin powder, 14 parts of vinyl acetate resin, 18 parts of diacetyl epoxy glycerin soybean oil, polycaprolactone-based polyurethane elastic 9 parts of body, 1 part of foaming agent, 16 parts of epoxy soybean oil, 25 parts of modified attapulgite, 1.6 parts of lubricant, 1.5 parts of silicone masterbatch, 1 part of stabilizer, 1.2 parts of pigment; Use titanium dioxide or other organic pigments.

[0026] The modified attapulgite is modified by the following steps:

[0027] (1) Crush the attapulgite, pass it through a 60-mesh sieve, soak it in an oxalic acid solution with a mass fraction of 5% for 1-2 hours, and then wash it with clean water until neutral;

[0028] (2) Soak the attapulgite treated in step (1) with 2.5% sodium dodecylbenzenesulfonate, which is 10 times the weight of the attapulgite, for 15-20 minutes, and use ...

Embodiment 2

[0039] An environmentally friendly wear-resistant and degradable PVC decorative artificial leather, made of the following raw materials: 140 parts of PVC resin powder, 15 parts of vinyl acetate resin, 20 parts of diacetyl epoxy glycerin soybean oil, polycaprolactone-based polyurethane elastic 9 parts of body, 1.1 parts of foaming agent, 16 parts of epoxy soybean oil, 30 parts of modified attapulgite, 1.3 parts of lubricant, 1.5 parts of silicone masterbatch, 2 parts of stabilizer, 1.1 parts of pigment; Attapulgite is modified using the following steps:

[0040] (1) Crush the attapulgite, pass it through a 60-mesh sieve, soak it in an oxalic acid solution with a mass fraction of 5% for 1-2 hours, and then wash it with clean water until neutral;

[0041] (2) Soak the attapulgite treated in step (1) with 2.5% sodium dodecylbenzenesulfonate, which is 10 times the weight of the attapulgite, for 15-20 minutes, and use ultrasonic vibration treatment during the soaking process ;

Abstract

The invention discloses a preparation method of clean, ecological and degradable PVC decorative artificial leather. The artificial leather is prepared from ecological PVC slurry, and the ecological slurry is prepared from the following components: PVC resin powder, vinyl chloride-vinyl acetate resin, diacetyl epoxy soybean glyceryl oleate, a polycaprolactone-based polyurethane elastomer, a foamingagent, epoxidized soybean oil, modified attapulgite, a lubricant, silicone masterbatch, a stabilizer and pigment. The artificial leather prepared with the treatment process is non-toxic, environmentally friendly and good in degradability and has good wear resistance.

Description

technical field [0001] The invention belongs to the field of artificial leather manufacturing, and in particular relates to an environment-friendly, wear-resistant and degradable PVC decorative artificial leather. Background technique [0002] The concept of ecological artificial synthetic leather includes the following four aspects: first, it does not pollute the environment during the manufacturing process; second, it is harmless in the process of processing it into leather products; The environment does not produce pollution; Fourth, it is biodegradable, and the degradation products will not cause new pollution to the environment. At present, when we refer to ecological synthetic leather, people emphasize that the product is harmless to the human body during use and does not pollute the environment. This is only one aspect of ecological synthetic leather. If we consider the other three elements: It can be said that we have not really realized ecological synthetic leather...
