Water-repellent and oil-repellent composition and application thereof

Abstract

The invention relates to a water-repellent and oil-repellent composition and application thereof. The water-repellent and oil-repellent composition provided by the invention comprises an oil-repellent component and an amide polymer, wherein the oil-repellent component is selected from an organic silicon polymer and / or an organic fluorine polymer. The composition can effectively eliminate foams generated in the manufacturing process while ensuring water resistance and oil repellency of an article, especially a paper-plastic product, so that the qualification rate of the product is improved.

Description

Technical Field

[0001] The present application relates to an oil-repellent and water-repellent composition containing a silicone or fluoropolymer and an amide polymer and its applications. Background Art

[0002] Paper pulp molded products have replaced plastic products and are widely used in food packaging, such as paper tableware or packaging boxes, due to their origin from natural pulp, easy degradation, and excellent properties. During the manufacturing process of paper pulp molding, sizing agents (waterproof agents) and oil-repellent agents are generally added in the wet end to endow the paper-plastic products with the functions of waterproofing and oil repellency. The waterproof agent is widely used such as alkyl ketene dimer (AKD) emulsion, while the oil-repellent agent is mainly silicone polymer or fluoropolymer.

[0003] The prior art CN114573767A describes a silicone polymer which, when applied to paper-plastic products, can endow the products with the function of oil repellency. CN1659197A describes a fluoropolymer which can also endow paper-plastic products with the function of oil repellency.

[0004] However, it is found in practical applications that after adding the above waterproof and oil-repellent auxiliaries, the pulp pool is particularly prone to foaming, and then yellow spots will be formed on the surface of the paper-plastic products, resulting in unqualified appearance inspection of the products. After adding traditional defoamers such as silicone, the foam cannot be effectively eliminated, and sometimes the waterproof and oil-repellent properties of the products will be affected.

[0005] Therefore, it has become an urgent task to develop an auxiliary with defoaming effect that does not affect the waterproof and oil-repellent properties of the products. Summary of the Invention

[0006] The purpose of the present application is to provide an oil-repellent and water-repellent composition, which contains a silicone or fluoropolymer as an oil-repellent agent and an amide polymer. The composition can effectively eliminate the foam generated during the manufacturing process while ensuring the waterproof and oil-repellent properties of articles, especially paper-plastic products, thereby improving the qualification rate of the products.

[0306] II. Test methods

[0307] Manufacturing method of pulp molding: Adding in the wet end

[0308] Directly pulping the bagasse pulp board, with the beating degree of 600 mL of Canadian freeness and the pulp concentration of 0.3%. Sequentially add a sizing agent of alkyl ketene dimer (AKD) (concentration 15%) to the pulp, and the addition amount is 0% - 4% of the weight of the absolutely dry pulp; then add the synthesized oil-repellent polymer, and the addition amount is 0.5% - 10% of the weight of the absolutely dry pulp; finally add the synthesized polyamide polymer, and the addition amount is 1% - 10% of the weight of the absolutely dry pulp.

[0309] Pour the pulp into a paper bowl mold filter screen with a diameter of 20 cm and a depth of 5 cm according to the specified weight, and then use vacuum filtration to remove the moisture. Bake in the mold at 150 °C for 120 seconds, and measure the weight of the paper bowl to be 20 ± 1 g, and evaluate the waterproof and oil-repellent properties of the paper bowl, etc.

[0310] Evaluation of foaming property:

[0311] Use Ross-Miles (Ross foam analysis method) for evaluation, and its main equipment is as Figure 1As shown, the height of the test tube is 900 mm, and the capacity of the top container is 200 mL. Take about 300 mL of the liquid to be tested, first inject 50 mL into the bottom of the tube, then fill the 200 mL top container. Open the valve of the top container, and the liquid will naturally rush into the liquid in the lower part of the test tube. After the liquid has drained, measure the height of the foam and record the time when the foam has disappeared by half.

[0312] Evaluation of oil and water repellency

[0313] 1) Evaluation of oil repellency test - Heat-resistant oil test

[0314] Pour hot oil (salad oil) at 85 °C onto the paper product, observe for 20 minutes to see if there is penetration, and conduct a rating.

[0315] 5 points means no color change on the surface;

[0316] 4 points means slightly color change on the surface;

[0317] 3 points means color change on the surface and slight penetration;

[0318] 2 points means severe penetration.

[0319] 2) Hot water resistance test

[0320] Pour boiling water at 100 °C into the paper-plastic molded product, observe for 30 minutes to see if there is leakage. Pass if there is no leakage, and fail if there is leakage.
