Problems solved by technology

[0004] However, the catalyst used in the commonly used hydrosilylation reaction is a platinum catalyst, and the hydrosilylation reaction using a platinum catalyst is prone to crosslinking, resulting in self-polymerization, and the synthesis of acrylate-modified silicone oil is relatively difficult. , the quality and yield of the acrylate-modified silicone oil produced are relatively low
[0005] In view of the above-mentioned related technologies, the inventor believes that the current preparation method of acrylate-modified silicone oil produces poor product quality, and the preparation method still needs to be improved

Embodiment 1

[0050] The preparation method of the acrylic acid modified silicone oil provided by embodiment 1 may further comprise the steps:

[0051] S1: Stir allyl acrylate, rhodium catalyst and polymerization inhibitor in the preparation tank at a stirring speed of 200r / min for 1 hour according to the above ratio, and cool down to 8°C during the stirring process to obtain a mixed raw material;

[0052] S2: put hydrogen-containing silicone oil into the feeding tank, and stir at a stirring speed of 200r / min, and adjust the temperature to 15°C to obtain pretreated hydrogen-containing silicone oil;

[0053] S3: Add the pretreated hydrogen-containing silicone oil to the mixed raw materials, stir the mixed solution at a stirring speed of 100r / min, wait for the temperature to stabilize and then raise the temperature to 70°C, and continue the heat preservation reaction for 2h;

[0054] Step S1 and step S2 are in no particular order.

[0055] After the above steps, the acrylic modified silicone...

Embodiment 15

[0059] The difference from Example 13 is that when preparing the acrylic modified silicone oil, the temperature of the mixed raw material is controlled at 7°C, and the temperature of the hydrogen-containing silicone oil is 14°C.

Embodiment 16

[0061] The difference from Example 13 is that when preparing the acrylic modified silicone oil, the temperature of the mixed raw materials is controlled at 6°C, and the temperature of the hydrogen-containing silicone oil is 12°C.

Abstract

The invention relates to the field of modified silicone oil, and particularly discloses acrylate modified silicone oil and a preparation method thereof. The acrylate modified silicone oil is characterized by being prepared from the following raw materials in parts by weight under the action of a catalyst: 100-120 parts of hydrogen-containing silicone oil, 150-200 parts of allyl acrylate, 2-5 parts of a polymerization inhibitor and 10-12 parts of a chain transfer agent, wherein the catalyst is a rhodium catalyst. The preparation method comprises the following steps: S1, uniformly mixing allyl acrylate, a rhodium catalyst and a polymerization inhibitor in proportion, and cooling to 5-8 DEG C to obtain a mixed raw material; s2, adjusting the temperature of the hydrogen-containing silicone oil to 10-15 DEG C to obtain pretreated hydrogen-containing silicone oil; s3, mixing the pretreated hydrogen-containing silicone oil and a mixed raw material for hydrosilylation reaction; the step S1 and the step S2 are not divided into a sequence. The method has the advantage that the product quality is improved.

Description

technical field [0001] The application relates to the technical field of UV resin additives, more specifically, it relates to an acrylate-modified silicone oil and a preparation method thereof. Background technique [0002] Acrylate-modified silicone oil, also known as silicone-modified acrylate, combines the advantages of silicone and acrylate, and has the advantages of cross-linking and non-migration. Adhesive and anti-scratch properties are improved. It can be used as an additive in UV light-curing system to help light-curing coatings improve special properties such as coolness, substrate wettability, anti-shrinkage, scratch resistance and leveling, and plays a very important role in the coatings industry. status. [0003] At present, the common acrylate-modified silicone oil is mainly prepared by reacting hydrogen-containing silicone oil and acrylate under the action of a catalyst by the method of hydrosilylation. [0004] However, the catalyst used in the commonly us...
