Problems solved by technology

[0002] Existing products can be used in elastic hand paint, most of them are single, and the effect is quite different. In the aspect of matting powder and anti-settling, there are added systems such as fumed silica, polyamide wax, organic bentonite, and thixotropic resin. Consistency thickener, this type of product has a significant anti-settling effect, but at the same time seriously affects the smoothness and fineness of the paint film. It is also feasible to use a dispersant to assist the dispersing of the matte component to achieve anti-settling, but the hand-feeling paint Two other types of additives (construction time prolonging agent and anti-blooming agent) should be added in it; combined, it is not convenient for customers to use

Embodiment 1

[0013] Raw materials and instruments:

[0014] Polyphosphoric acid, epoxy polyglycol ether, monobutyltin oxide, hydroquinone, tetraisopropyl titanate catalyst, sodium dodecylbenzenesulfonate, sodium bicarbonate.

[0015] T25Digtial digital display disperser mixer, Shanghai Pegasus Company, MX-50 moisture analyzer, Japan Akun D Company, IL thermoelectric reaction type temperature controllable reaction kettle.

[0016] making process:

[0017] First add epoxy-based polyethylene glycol ether at room temperature, and at the same time start the mixer and slowly raise the temperature to 70°C within 20 rpm under mild conditions, then add polyphosphoric acid, monobutyltin oxide (parts per ten thousand) 5), hydroquinone (2 / 10,000) and tetraisopropyl titanate catalyst, add sodium dodecylbenzenesulfonate and sodium bicarbonate at the same time, keep the temperature between 70°C and 85°C, about 5 Hours later: When the viscosity reaches 300mpa.s, 30°C, and the acid value is 110mgkoH / g, t...

Abstract

The invention relates to a phosphatide-type auxiliary agent used for a soft-touch feeling paint and a preparation method thereof. A chemical formula of the phosphatide-type auxiliary agent is shown in a specification, wherein R is shown in the specification, n is an integer which is greater than 0. The combining power of partial glycol ethers group and matting powder of the phosphatide-type auxiliary agent makes the orientation and arrangement of the matting powder more uniform and consistent, so that the floating problem of the matting powder in the soft-touch feeling paint can be effectively improved. The phosphatide-type auxiliary agent used in the soft-touch feeling paint which is researched by our company has the characteristics of technology leading, uniqueness and exclusiveness, and has obvious effect for enlarging client application.

Description

technical field [0001] The invention relates to a phosphoester-type auxiliary agent used in soft-touch feeling paints and a preparation method thereof. The product is mainly used in soft-touch feeling paints to prevent the precipitation of matting powder, prolong the construction time, and at the same time Effectively improve the flowering of the paint film. Background technique [0002] Existing products can be used in elastic hand paint, most of them are single, and the effect is quite different. In the aspect of matting powder and anti-settling, there are added systems such as fumed silica, polyamide wax, organic bentonite, and thixotropic resin. Consistency thickener, this type of product has a significant anti-settling effect, but at the same time seriously affects the smoothness and fineness of the paint film. It is also feasible to use a dispersant to assist the dispersing of the matte component to achieve anti-settling, but the hand-feeling paint Two other types of ...
