Problems solved by technology

However, the existing PVC surface treatment agent needs to be treated with the second version to make the surface treatment agent penetrate into the bottom of the pattern, which increases the amount of surface treatment agent, increases the production cost of the manufacturer, and thus also increases the pollution to the environment.

Example Embodiment

[0040] See figure 1 , The present invention also provides a method for preparing a surface treatment agent for PVC synthetic leather. The surface treatment agent for PVC synthetic leather is a bright surface treatment agent, comprising:

[0041] S101. Put 75-90% solvent and 0.1-3% auxiliary agent into the reaction kettle and start stirring.

[0042] More preferably, put 80-90% solvent and 0.1-1% auxiliary agent into the reactor and turn on the stirring.

[0043] S102. Slowly put in 5-20% vinyl acetate resin and 2-8% polymethacrylic acid while stirring, and heat to 65-80°C for 3-5 hours.

[0044] More preferably, slowly add 10-20% vinyl acetate resin and 2-8% polymethacrylic acid under stirring, and heat to 65-80°C for 4 hours.

[0045] S103. After all the materials are dissolved, the temperature can be lowered and packaged to obtain a finished product.

[0046] Wherein, the auxiliary agent is a modified silicon-based auxiliary agent. Specifically, the auxiliary agent BYK-337 or MHC30-313...

Example Embodiment

[0070] Example 1

[0071] Weigh 45 parts of toluene, 37.8 parts of methyl ethyl ketone, and 0.2 parts of modified silicon additives (BYK-337) in 3 times the amount accurately and put them into the reaction kettle, turn on the stirring, and slowly add the vinyl acetate resin under stirring. 11 3 times the amount of 6 parts of polymethacrylic acid, heated to 80°C for about 4 hours, cooled and packaged to prepare a PVC bright surface treatment agent.

Example Embodiment

[0072] Example 2

[0073] Put 42 parts of toluene and 38.2 parts of methyl ethyl ketone into the dispersing tank with a mixer in 3 times the amount, turn on the slow stirring, and then slowly add 13 parts of vinyl acetate resin 3 times the amount into the dispersing tank, and disperse at high speed for 40 minutes. Adjust the speed of the mixer to slow down, add 1 part of dispersant MHC10-1140, 0.8 part of auxiliary MHC30-3130, and 5 parts of matting agent in 3 times the amount and in order, disperse at high speed for 30 minutes, and then place it in a sand mill at room temperature. The second time, after the fineness is qualified, filter and package, and prepare PVC matte surface treatment agent.

Abstract

The invention discloses a PVC synthetic leather surface treating agent which is prepared from a component A and a component B. The component A comprises 75-90% of a solvent, 5-20% of a vinyl chloride-vinyl acetate copolymer, and 0.1-3% of an auxiliary agent, wherein the auxiliary agent is a modified silicon auxiliary agent; the component B comprises 2-8% of polymethylacrylic acid, or comprises 0.1-3% of a dispersant and 3-8% of a matting agent. Accordingly, the invention also discloses a preparation method of the PVC synthetic leather surface treating agent, PVC synthetic leather prepared by applying the surface treating agent and a preparation method of the PVC synthetic leather. By adopting the surface treating agent, when a leather is subjected to surface treatment, one-plate treatment (i.e. one-time starching) is only required, then the surface treating agent can evenly permeate into a glue layer of the leather, even though a leather has deeper patterns, and the surface treating agent also can quickly permeate to the pattern bottom and evenly surfacely coats the leather surface, so that the leather surface after surface treatment is starched evenly and beautifully.

Description

technical field [0001] The invention relates to the technical field of leather surface treatment, in particular to a PVC synthetic leather surface treatment agent, PVC synthetic leather and a preparation method thereof. Background technique [0002] People need to apply a large amount of PVC artificial leather in daily life, and because a large amount of plasticizers and other materials are added in the production of PVC artificial leather, the produced PVC artificial leather is not ideal in terms of luster and hand feeling. In order to achieve a better and more ideal use effect, the leather surface must be treated during the leather production process to endow the leather surface with smooth, soft, matting, waterproof, anti-fouling and other comfortable feel and beautiful appearance. [0003] The existing PVC surface treatment agent (referred to as the surface treatment agent) has not reached a good state of permeability and leveling, so when the leather surface is treated,...
