Problems solved by technology

The same is true for defoamer products. Concentrated defoamers have the characteristics of low cost and high performance, but in view of the stability problems of high-content defoamers and the high turbidity added to liquid detergents, there These products are always in short supply

preparation example Construction

[0080] The preparation method of component B:

[0081] The corresponding modifying group R with unsaturated double bonds shown in Table 1 1 , R 2 and R 3 It is obtained by reacting with hydrogen-containing polyorganosiloxane under the action of isopropanol solution of chloroplatinic acid with a platinum content of 1-20ppm, in which various modified groups are grafted to hydrogen-containing polyorganosiloxane through random polymerization on the oxane backbone. The hydrogen-containing polyorganosiloxane is at least one hydrogen-containing polyorganosiloxane whose general structure is as follows: Me 3 SiO(MeHSiO) p (Me 2 SiO) q SiMe 3 , where the corresponding values ​​are: Me is methyl, b+c+d=p, a=q; each molecule has at least 2 silicon-bonded hydrogen atoms; the kinematic viscosity at 25°C is 20~ 5,000mPa·s.

Embodiment 1-2

[0089] The preparation method of embodiment 1-2:

[0090] Mix component A and component B prepared by the known technique shown in Table 3 and heat to 55°C. After stirring at 150rpm for 0.5h, keep the temperature constant and add C1. After stirring evenly, pass through a colloid mill to homogenize After chemical treatment, add C2 and C3 and stir evenly to obtain the defoamer composition.

Abstract

The invention discloses an organic-silicon defoaming agent composition. The organic-silicon defoaming agent composition with a specific assembling structure and high content is prepared by adopting compounding of cross-linking type polyether-polydi-organic-group siloxane and branched-chain type polyether-polydi-organic-group siloxane and matching with the synergistic effect of polyether polyol and has good wrapping and dispersing effects for organic-silicon defoaming active matters with alkyl structures so as to have more-ideal foam control effect in a liquid detergent and simultaneously have better stability and smaller turbidity value.

Description

technical field [0001] The discovery provides a high-content foam control agent for liquid detergents, which has a better foam control effect in detergents and can better maintain the clarity of detergents, and belongs to the technical field of fine chemicals. Background technique [0002] Liquid detergents are people's daily necessities, with unique advantages such as easy to use, fast dissolution, and milder to fabrics and skin. Due to the foam stabilizing effect of the surfactant, it is difficult to rinse the foam, which not only wastes water resources, increases the cost of laundry, but also causes large-scale water pollution, which is not conducive to energy saving, emission reduction and environmental protection. Currently, this problem is usually pinned on to be solved by adding silicone antifoams to the detergent mixture components. However, in addition to the foam control effect, the stability and clarity of silicone antifoams in detergents are two other properties...
