Problems solved by technology

Their defect is that they have poor compatibility with glue, poor dispersion performance, and without exception contain polysiloxane (silicone oil) components with poor compatibility, which often lead to parking accidents, and the appearance of the product is relatively poor. Poor, opaque film, etc.

Embodiment 1

[0024] First, add mineral oil to the reaction kettle at a temperature of 50-80°C, raise the temperature to 120-180°C, add a hydrophobic modified thickener, and stir and mature at about 150°C for 10-15 hours, then lower it to room temperature, add Silicone polyether surfactant, anti-fungal agent, anti-rust agent, mixed evenly under high-speed dispersion, and the finished product can be obtained after discharging. Among them, 35 parts of silicone polyether surfactant, 30 parts of mineral oil, 2 parts of hydrophobically modified thickener, 2 parts of mold inhibitor, and 2 parts of rust inhibitor.

Embodiment 2

[0026] In addition to 50 parts of silicone polyether surfactant, 25 parts of mineral oil, 2 parts of hydrophobically modified thickener, 3 parts of antifungal agent, and 3 parts of rust inhibitor. , all the other implementations are the same as in Example 1.

Embodiment 3

[0028] In addition to 60 parts of silicone polyether surfactant, 30 parts of mineral oil, 2 parts of hydrophobically modified thickener, 2 parts of antifungal agent, and 3 parts of rust inhibitor. , all the other implementations are the same as in Example 1.

Abstract

The invention provides a defoaming agent composition, which comprises the following components in part by weight: 35 to 65 parts of organic silicon polyether surfactant, 20 to 30 parts of mineral oil, 1 to 2 parts of hydrophobic modified thickener, 2 to 3 parts of mildew-proof agent and 2 to 3 parts of anti-rusting agent. The foaming agent has excellent foam eliminating and inhibiting performance, can be used for eliminating and cleaning aqueous phase foam in the production processes of the industries of chemicals, water treatment, paper making and the like, can also be used as a foam inhibiting component in printing and dyeing, water treatment, cleaning, daily chemical auxiliary agents and mechanical auxiliary agents, and is particularly suitable to be used as a foam eliminating and inhibiting component in high-alkali detergents for beer bottles, milk bottles and the like.

Description

technical field [0001] The invention relates to the field of defoamers, more specifically, the invention relates to a novel defoamer for polyorganosiloxane modified adhesives. Background technique [0002] The existence of foam in the industrial production process will hinder production and product application. Foam must be eliminated. Usually, defoamers are added to achieve the purpose. Therefore, defoamers must have defoaming and foam suppression functions. Defoaming is mainly based on the Ross theory, and the defoaming agent must be "insoluble" to the foaming solution and can be easily dispersed in the foaming solution. A good defoamer can not only break the foam quickly, but also maintain no foam for a certain period of time. [0003] In order to overcome the defects of adhesives, especially adhesives with more viscous monomers, which use water as a solvent, to produce foam during synthesis, storage, transportation and processing of coating films, and to overcome bloomi...
