Problems solved by technology

[0003] Synthetic leather, especially PVC leather, has high requirements for the ironing process. Due to technical bottlenecks, it is difficult to increase the solid content of some existing resin compositions suitable for the ironing process. If it reaches high solids (above 30%), The viscosity of the composition is usually above 200,000Pa·S, it is solid, and the coating process is very difficult, and it is difficult to make the leather surface after ironing treatment achieve good waxy feeling, good oily feeling and high gloss at the same time

Embodiment 1

[0018] A high-solid ironing bright waxy resin composition for synthetic leather, each raw material component is weighed according to the following weight ratio: polyvinyl chloride 50%, dioctyl phthalate 35%, emulsifying wax 3%, hard wax Fatty acid 5%, polyether modified silicone oil 2%, cellulose ester 2%, CaCO 3 3%.

[0019] The production process of the resin composition is as follows: the above-mentioned substances are accurately weighed in proportion and fully stirred (stirred for at least 30 minutes) in a reaction kettle to obtain a high-solid ironing bright waxy resin composition for synthetic leather.

[0020] The resin composition of the present invention obtained through the above steps is a white viscous liquid with a pH value of about 6-7, a solid content of 70±1%, and a viscosity of 5000-6000 Pa·S at 25°C.

[0021] The high-solid hot bright waxy resin composition for synthetic leather prepared by the above production process has a high solid content, but the visc...

Abstract

The invention relates to a high-solid scalding bright wax feeling resin compound for synthesizing leather. The compositions of the resin compound in weight percentage are: 45 to 55 percent of polyvinyl chloride, 30 to 40 percent of dicapryl phthalate, 1 to 6 percent of emulsified wax, and 4 to 10 percent of stearine. Compared with the prior art, the high-solid scaling bright wax feeling resin compound for synthesizing leather has high solid content and low viscosity, can satisfy the resin coating technique and solves the difficult problem in the prior art; the made leather surface feels like wax after scalded, feels like oil and has good lustrousness.

Description

technical field [0001] The invention relates to a resin composition for synthetic leather suitable for the ironing process, in particular to a polyvinyl chloride resin composition for the synthetic leather suitable for the ironing process. Background technique [0002] Synthetic leather is usually divided into PU leather (polyurethane leather) and PVC leather (polyvinyl chloride leather). During the manufacturing process of PVC leather, the plastic (PVC) particles should be hot-melted and stirred into a paste, and the cloth base should be evenly coated according to the specified thickness. Then enter the foaming furnace for foaming, so that it has a softness that can adapt to the production of various products and different requirements. Surface treatment (dyeing, embossing, polishing, matting, grinding) fluffing, ironing, etc.). [0003] Synthetic leather, especially PVC leather, has high requirements for the ironing process. Due to technical bottlenecks, it is difficult t...
