Problems solved by technology

In order for the washi tape to be anti-sticking, the writing and backing must meet the characteristics of moderate release force and good unwinding performance. If the release force is too light, it cannot be written or backed. If the release force is too heavy, it will easily cause difficulty in unwinding. , even poor release
The invention with application number 201610002701.8 discloses a release film with ultra-light release force and its preparation method. The invention makes the original release film have ultra-light release film by adding a silicone oil layer to the release film and the release layer. The release force increases the chemical cross-linking density of the release layer at the same time, but the invention constructs a three-layer release film structure, which requires layered coating, and there may be a problem that the release force is too light

Embodiment 1

[0020] First, mix the mixture of 4kg vinyl acrylate and hydrogen-containing silicone oil emulsion with 10kg deionized water for 15 minutes until uniform, and dilute the hydrogen-containing silicone oil modifier to facilitate the cross-linking of the hydrogen-containing silicone oil emulsion; Mix well and add 0.16 kg of chloroplatinic acid additive to the diluted hydrogen-containing silicone oil modifier and stir together for 3 minutes until uniform to obtain a uniformly dispersed interface modifier, and add it to the mixture of hydrogen-containing silicone oil modifier and platinum additive Add 0.01 kg of antifoaming agent polydimethylsiloxane to the mixture for defoaming; finally, add 100 kg of silicon-modified polyvinyl acetate emulsion to the diluted interface modifier and stir together for 10 minutes until uniform. After the silicon-modified polyvinyl acetate emulsion is mixed, the interface modifier can be cross-linked on the surface of the silicon-modified polyvinyl aceta...

Embodiment 2

[0022] First, mix 10kg of vinyl acrylate, hydrogen-containing silicone oil emulsion and 30kg of deionized water for 30 minutes until uniform. And add 0.4 kg of chloroplatinic acid complex additive to the diluted hydrogen-containing silicone oil modifier and stir together for 5 minutes until uniform, to obtain a uniformly dispersed interface modifier, and add the hydrogen-containing silicone oil modifier and platinum additive Add 0.02kg of a mixture of antifoaming agent polydimethylsiloxane and polyoxypropylene glyceryl ether to the mixture for defoaming; finally, add 200kg of silicon-modified polyvinyl acetate emulsion to the diluted interface modifier and stir together for 20 Minutes to uniformity, under the catalysis of chloroplatinic acid additives, the interface modifier can cross-link silicon-modified polyvinyl acetate emulsion to form a very thin silicone oil layer, which can be used for color printing and paper after discharge. Water-based release agent, all the stirrin...

Embodiment 3

[0024] First, mix 10kg of vinyl acrylate, hydrogen-containing silicone oil emulsion mixture with 30kg of deionized water and stir for 25 minutes until uniform. Add 0.4 kg of chloroplatinic acid complex additive to the homogeneous and diluted hydrogen-containing silicone oil modifier, and stir together for 5 minutes until uniform, to obtain a uniformly dispersed interface modifier, and add the hydrogen-containing silicone oil modifier and platinum Add 0.02 kg of defoamer polyoxypropylene glyceryl ether to the mixture of additives for defoaming; finally, add 200 kg of silicon-modified polyvinyl acetate emulsion to the diluted interface modifier and stir together for 20 minutes until uniform, and the interface modifier Under the catalysis of chloroplatinic acid additives, it can be cross-linked on the surface of silicon-modified polyvinyl acetate emulsion to form a very thin silicone oil layer. After discharging, it can be used as a water-based release agent for color printing and...

Abstract

The invention discloses a water-based release agent for color printing and paper adhesive tapes and a preparation method thereof. The formula comprises the following components by weight: 100-200 parts of a silicon modified polyvinyl acetate emulsion, 4-10 parts of a hydrogen-containing silicone oil modifier, 0.16-0.4 part of a platinum assistant, 10-30 parts of deionized water, and 0.01-0.02 partof a defoaming agent. The water-based release agent provided by the invention improves the antisticking, writing and back sticking functions of color printing and paper adhesive tapes on the market,and the improved water-based release agent can provide appropriate release force and low migration rate to color printing and paper adhesive tapes. At the same time, the water-based release agent hasthe advantages of convenient use, direct coatability or coating after dilution with water, simple making method, and convenient operation, and is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of release materials, in particular to a water-based release agent for color printing and paper tapes and a preparation method thereof Background technique [0002] Color printing washi tape is mainly used for spraying / masking / beauty of DIY / electronics, furniture, office furniture, wood, musical instruments, metal, rubber and other parts that require color printing. Color printing washi tape is mainly composed of three parts: washi base paper, adhesive and release agent. The release agent, also known as anti-sticking agent and release agent, is one of the important materials for the production of color printing and paper tapes. It has an important impact on the function and application of color printing and paper tapes. The basis of washi tape, for color printing and washi tape, the choice of release agent is more important. In order for the washi tape to be anti-sticking, the writing and backing must meet...
