Wherein w is more than or equal to 3, x is more than or equal to 1.
In the present application, the raw materials and equipment are all commercially available common products unless otherwise specified. The release agent used for the experiment is selected from a commercial GS5005 condensed type release agent with the viscosity of 1200cps, and the preparation formula is as follows:
g5005 condensed type release agent: 100 parts of (A);
120# solvent oil: 1900 parts of (A);
an adhesion promoter: 2 parts of (1);
and (3) antifogging agent: 50 parts of a mixture;
organotin catalyst: and 2 parts of the raw materials.
The release agent had a peel strength of 0.270N/mm, as determined without the addition of an anti-fogging agent.
In the present application, the properties of the following anti-fog additives were judged by the following methods:
anti-fogging performance: under a clean environment, an aerosol detector is adopted for measurement, and whether aerosol is detected or not is measured at a certain linear velocity so as to judge the anti-fogging performance of the aerosol.
Under the experiment, the anti-fogging effect brought by different anti-fogging agents and different mixing ratios of the same anti-fogging agent can be judged.
And (3) testing the performance of the release agent: specifically referring to GB/T25256-2010 optical function film-release film 180-degree peeling force and residual adhesion rate test method, the property of the release agent is determined by adopting a mode of a PET release film peeling force tester to measure the peeling strength of the release agent, wherein the thickness of the release film after the release agent is coated is 0.019mm.
The selected release agent is silicone oil,
in addition, for the convenience of calculation, the molar ratio of the silicon-hydrogen bond to the vinyl group is estimated as follows:
a is the mass of the branched vinyl silicone oil;
MA is the vinyl mole fraction in the branched vinyl silicone oil;
b is the mass of hydroxyl-terminated vinyl silicone oil
MB is the vinyl mole fraction in the hydroxyl terminated vinyl silicone oil;
c is the mass of hydrogen-containing silicone oil;
MC is the mole fraction of silicon-hydrogen bonds in the hydrogen-containing silicone oil.
In the above calculation method, since the average molecular weights of the three silicone oils are actually close to each other, they are uniformly omitted, and the actual calculation results are close to the above calculation results under the conditions in the present application.
The technical solution of the present application will be described by the following examples and comparative examples.
Example 1, relates to an anti-fogging additive, which is prepared by a process comprising the steps of:
s1, carrying out catalytic reaction on hydrogen-containing silicone oil and branched vinyl silicone oil under the action of a platinum catalyst, wherein the using amount of the hydrogen-containing silicone oil is 100g, the number average molecular weight is 5000, and the hydrogen molar content is 0.5%.
The mass of the platinum catalyst is 0.1 percent of that of the hydrogen-containing silicone oil;
the vinyl molar content of the branched vinyl silicone oil is 0.6 percent, and the number average molecular weight is 12000; the mass used was 75g;
in this step, the temperature was increased stepwise from 20 ℃ (room temperature) to 90 ℃, wherein the number of temperature steps was 5, and the interval between two temperature increases was 30min.
S2, adding double-end vinyl silicone oil into the system, and reacting for 30min in a heat preservation manner;
wherein the number average molecular weight of the double-ended vinyl silicone oil is 5000, and the used mass is 15g.
S3, uniformly adding hydroxyl-terminated vinyl silicone oil into the system within 30-60 min, and then naturally cooling to 60 ℃. The reaction was continued and the viscosity was measured until the viscosity reached 10000cps, and the reaction was terminated by rapid cooling.
Wherein the number average molecular weight of the hydroxyl-terminated vinyl silicone oil is 10000, and the vinyl molar content is 1.0 percent; the dosage is 10g.
The molar ratio of vinyl groups to silicon-hydrogen bonds was calculated to be 1: 1.1 in example 1.
In contrast to example 1, comparative examples are as follows:
example 2, a specific preparation procedure for the anti-misting additive was as follows:
s1, on the basis of the embodiment 1, changing the using amount of the branched vinyl silicone oil to 100g;
and step S2 is kept unchanged, the temperature is naturally reduced to the room temperature after the step S2 is finished, and the step S3 is deleted.
Example 3 differs from example 1 in that step S3 is deleted and a corresponding mass of hydroxyl-terminated vinyl silicone oil is added after the reaction has ended.
Embodiment 4 differs from embodiment 1 in that step S2 is deleted.
Example 5 differs from example 1 in that step S2 is deleted and after the end of the reaction i has cooled to room temperature the corresponding mass of terminal vinyl silicone oil is added.
Comparative example 1, a combination of hydrogen-containing silicone oil, branched vinyl silicone oil, terminal vinyl silicone oil and hydroxyl-terminated vinyl silicone oil in the same mass ratio as in example 1 was directly mixed and used as an antifogging agent.
The anti-fogging additives obtained in examples 1 to 5 were measured, and the viscosity and anti-fogging properties thereof are specifically shown in Table 1.
Table 1, experimental results of examples 1 to 5
In the above table, the roller speed is the surface linear velocity, and increases by 100m/min as the initial velocity, and increases by 10m/min each time until 350m/min or the aerosol detector detects the aerosol. The same measurement method was used in the following experiments.
As can be seen from the data in Table 1, the above-mentioned adjuvants, when directly mixed, do not have the effect of anti-fogging, and actually, the main anti-fogging effect in the composition is actually a network cross-linked structure formed by vinyl silicone oil and hydrogen-containing silicone oil. Although a network silicone oil system formed by crosslinking the branched vinyl silicone oil and the extruded hydrogen-containing silicone oil can effectively improve the adhesive capacity of the release agent on the surface of the roller and reduce the flying fog phenomenon caused by the over-high rotating speed of the roller, and meanwhile, the adhesive performance of the release agent is not obviously changed.
Among the components added thereto, the terminal vinyl silicone oil, although not providing higher complexity in the silicone oil complex crosslinking system participating in the network structure, can provide necessary double-terminal connection to further link different silicone oil network structures together, so that the anti-fogging agent in example 1 has significantly improved anti-fogging performance compared with examples 2 and 3. In the presence of hydroxyl groups, the release agent can be better transferred from the surface of the roller to the surface of the paper, and the generation of release agent atomization is also reduced.
Further, in addition to example 1, the following examples can be obtained by adjusting each parameter.
Example 6, the effect of the viscosity of the final anti-fogging agent on the results under different experimental conditions was investigated and the results obtained are shown in table 2.
Table 2, example 6 investigation results of experimental parameters
In step S1, the crosslinking degree of the silicone oil obtained by the preparation can be controlled more effectively by stepwise temperature increase, and in the temperature increase, it can be seen that if the method (6-6) of raising the temperature to 90 ℃ at a time and maintaining the reaction is adopted, the crosslinking degree is excessively high in step S1, and the subsequent reaction is adversely affected. When the crosslinking degree in the step S1 is too low (e.g., 6-3 to 6-5), a good network structure cannot be realized in the subsequent reaction, and the antifogging agent prepared by the method has poor antifogging property.
Experiments 6-8 to 6-11 show that the antifogging agent can exert better antifogging effect within the viscosity range of 1000 to 20000cps, and has no obvious influence on a release agent, and the antifogging agent with excessively high viscosity can easily generate crosslinking with an organic phase, so that the peeling strength is increased.
Although the viscosity can be increased by extending the reaction time in both of step S1 and step S3, even if the final viscosity is the same, if crosslinking does not occur sufficiently in step S1, the optimum antifogging effect is still provided. The reason for this may be that, in step S2, after the vinyl-terminated silicone oil and the hydrogen-containing silicone oil are subjected to a crosslinking reaction, the subsequent silicone oil (either unreacted vinyl silicone oil or hydroxyl-terminated vinyl silicone oil) with vinyl contained in the branched chain is difficult to undergo a complex crosslinking reaction with the hydrogen-containing silicone oil through a steric hindrance effect, and therefore, although the viscosity reaches a standard, the internal network structure cannot perfectly achieve the purpose of improving the anti-fogging performance.
On the basis, the influence of the properties and the proportion of the hydrogen-containing silicone oil, the branched vinyl silicone oil, the double-end vinyl silicone oil and the hydroxyl-end vinyl silicone oil on the antifogging agent is researched, and the method specifically comprises the following experimental groups.

Further, on the basis of the above parameters, the influence of the molecular weight of each component on the properties of the silicone oil obtained was investigated to obtain example 8, and the specific different experimental groups are shown in table 4.
Viscosity and experimental results in example 8
Through the data of the embodiment 7 and the embodiment 8, the parameter adjustment in the range has no obvious influence on the overall anti-fog performance, and the better anti-fog effect can be better realized at the highest rotating speed of the existing industry, but the excessive high or insufficient overall viscosity has certain influence on the peeling strength of the release agent.
In addition, it is not shown in the experimental data that when the amount of the hydroxyl-terminated vinyl silicone oil is too high, the partial residual hydroxyl groups of the hydroxyl-terminated vinyl silicone oil can have a significant influence on the separation performance of the release agent, so that the peel strength is significantly improved, and the properties of the release agent are further affected, therefore, the amount of the hydroxyl-terminated vinyl silicone oil should not exceed 15% of the total amount of the vinyl silicone oil.
