Embodiment 1

[0026] The raw materials and weight ratios of ecological PVC slurry are as follows:

[0027] S-5 calcium carbide polyvinyl chloride powder 100 parts

[0028] Epoxidized soybean oil 50-60 parts

[0029] 5-6 servings of non-heavy metal color cake

[0030] PVC composite stabilizer 2 parts

[0031] Foaming agent AC 1 part

[0032] 30 parts of shell powder passed through a 600-mesh sieve;

[0033] According to the ingredients, the above-mentioned materials measured are input into the high-speed mixer through the pulse feeder, and the temperature is controlled at 100-150 ° C. After fully stirring, they enter the internal mixer, and the temperature is controlled at (160 ° C) for several minutes; After the base material (various fabrics) is opened, the PU slurry (150°C) is applied to open the width, and the fully mixed PVC slurry enters the four-roll calender (temperature 160-190°C) and the base material on which the PU slurry is applied Combining, cooling to normal temperature a...

Abstract

The invention discloses ecological PVC decorative artificial leather and a preparation method thereof. The artificial leather is prepared from ecological PVC pulp by adopting a calendaring method, wherein the ecological PVC pulp is prepared from the following components in part by weight: 100 parts of PVC resin powder, 40 to 80 parts of epoxy soybean oil, 2 to 10 parts of non-heavy metal color cake, 3 to 7 parts of stabilizer and foaming agent and 20 to 40 parts of shell powder. The artificial leather of the invention not only has good mechanical property, but also has higher folding strength and ageing resistance; and the leather also has the effects of adsorbing formaldehyde, decomposing the formaldehyde and adjusting air temperature.

Description

technical field [0001] The invention belongs to the field of artificial leather manufacture, and in particular relates to an ecological type PVC artificial leather and a preparation method of the ecological type PVC artificial leather. Background technique [0002] Artificial leather is the first invention to be used as a substitute for leather fabrics. It is made of PVC, plasticizer and other additives and calendered on cloth. At present, in the production process of domestic PVC decorative artificial leather, plasticizers, PVC resin powder, heavy calcium, stabilizers, foaming agents, color cakes and other main raw materials are usually used. This kind of artificial leather is easy to become hard and brittle, and chemical raw materials such as plasticizers will bring environmental pollution to the decorative artificial leather. Contents of the invention [0003] The object of the present invention is to provide an ecological type PVC decorative artificial leather which h...
