Problems solved by technology

[0003] The existing material surface modifiers are expensive, poor in stability, pollute the environment, and affect human health, and mainly focus on improving the surface strength of the material, and do not have flame retardancy
However, paper, fabric, and wood are all flammable products. Due to their flammability and extensive use, fire accidents have occurred frequently and countless, which pose a serious threat to life and the environment, and cause huge social and economic losses.

preparation example Construction

[0068] Another aspect of the present invention provides a method for preparing an alkenyl silicon phosphorus-vinyl acetate copolymer emulsion, preferably the method for preparing the alkenyl silicon phosphorus-vinyl acetate copolymer emulsion described in the first aspect of the present invention, the method comprising The following steps:

[0069] Step 1, adding a protective colloid and an emulsifier into a solvent to obtain a reaction system;

[0070] Step 2, adding alkenyl silicon phosphine oxide and vinyl acetate monomer to the reaction system, and reacting;

[0071] Step 3, post-processing to obtain alkenyl silicon phosphorus-vinyl acetate copolymer emulsion.

[0072] In the present invention, vinyl acetate monomers are copolymerized with alkenyl silicon phosphine oxide (silicon-phosphorene-based monomers) to obtain copolymer emulsions, which are used as surface modifiers for paper, fabrics, and wood, and are applied to paper, fabrics, and wood. On the surface, it can f...

Embodiment 1

[0095] Mix 3mL of hydroxymethylphosphine oxide (THPO) and 20mL of DMF evenly, then add 1.5mL of triethylamine, stir and mix evenly to obtain a mixed solution;

[0096] Introduce nitrogen, heat up to 60°C, add 6mL MVDCS while stirring, reflux for 5h, cool to obtain the reaction product;

[0097] The resulting reaction product was extracted, concentrated by evaporation, and dried under vacuum at 50° C. to obtain alkenyl silicon phosphine oxide with a yield of 68%.

Embodiment 2

[0099] The preparation process of Example 1 was repeated, the only difference being that the reflux reaction time was 4 h, and other steps were the same as in Example 1 to obtain alkenyl silicon phosphine oxide with a yield of 52%.

Abstract

The invention relates to the field of material surface modification, and discloses alkenyl silicon phosphine oxide and a preparation method thereof, and alkenyl silicon phosphorus-vinyl acetate copolymer emulsion and a preparation method and application thereof. The alkenyl silicon phosphine oxide is prepared from hydroxyl phosphine oxide and an alkenyl silane coupling agent; the alkenyl silicon phosphine oxide and vinyl acetate are copolymerized to obtain the alkenyl silicon phosphorus-vinyl acetate copolymer emulsion, the copolymer emulsion contains rich silicon and phosphorus elements, thesilicon and phosphorus are synergistically flame-retardant, and the obtained copolymer emulsion can be used as a material surface modifier and has excellent thermal stability, hydrolysis resistance and hydrophobicity. The copolymer emulsion is applied to the surfaces of materials such as paper, fabrics, wood and the like, and can endow the materials with excellent surface properties and flame retardancy. The preparation method of the copolymer emulsion provided by the invention is simple in process, low in cost, green and environment-friendly, wide in application range and easy for industriallarge-scale popularization, and has a good application prospect and great market competitiveness.

Description

technical field [0001] The invention relates to the field of material surface modification, in particular to an alkenyl silicon phosphorus-vinyl acetate copolymer emulsion and a preparation method and application thereof. Background technique [0002] Paper, fabric, and wood are the three indispensable daily materials in today's society. They are the necessities of people's work and life. They are widely used and used in a huge amount. Material surface modifiers are fine chemicals used to improve the properties of materials such as paper, fabrics, wood, etc., by spraying emulsions on the surface of materials to form adhesive films to improve material properties. [0003] The existing material surface modifiers are expensive, have poor stability, pollute the environment, and affect human health. They mainly focus on improving the surface strength of materials, and do not have flame retardancy. However, paper, fabric, and wood are all flammable products. Due to their flammabi...
