[0042] Examples 1-6: Preparation of self-emulsifying acrylic silicone wax protective material

[0043] The materials corresponding to Examples 1-6 were prepared according to the formula in Table 1.

Embodiment 1

[0047] In a 500mL three-necked flask equipped with a reflux device, 100g of low-hydrogen-containing polymethylhydrogensiloxane (also known as low-hydrogen silicone oil, with an active hydrogen content of 0.38wt%) and 60.5g of 1-18 ene, stirred, and added 1 g of platinum divinyltetramethyldisiloxane double-head complex solution (Karsted catalyst) (the concentration of platinum is 1,500 ppm, and the amount of platinum is low-hydrogen-containing polymethylhydrogen silicon 15ppm of oxane mass), heated to 120°C for 3 hours, cooled to 70°C, added 10g of acrylic acid (AA) and 2g of vinyl MQ silicone resin (Vi-MQ, the mass content of vinyl is 1.2wt%), 70 ℃ heat preservation reaction for 3 hours. Then it was cooled to room temperature to obtain the acrylic silicone wax polymer SAQ1. Take 100g of it, and slowly add 25g of ammonia water (the ammonia concentration is 5.6wt%) (a mixture of 10wt% ammonia water 14g and water 11g) under stirring to prepare a self-emulsifying acrylic silicone...

Embodiment 2

[0049] Into a 500mL three-necked flask equipped with a reflux device, 100g of low-hydrogen silicone oil (active hydrogen content of 0.38wt%) and 30.0g of 1-dodecene were sequentially added, stirred, and 1g of Karsted catalyst was added (the concentration of platinum was 1,000ppm, the amount of platinum used is 10ppm of the mass of low-hydrogen polymethylhydrosiloxane), heated to 100°C for 3 hours, cooled to 80°C, and then added 15g of acrylic acid (AA) and vinyl MQ silicone resin (Vi -MQ, vinyl mass content is 1.2wt%) 5g, heat preservation reaction at 80°C for 4 hours. Then cooled to room temperature to obtain acrylic silicone wax polymer SAQ2. Take 100g of it, and slowly add 25g of ammonia water (ammonia concentration is 10wt%) under stirring to prepare a self-emulsifying acrylic silicone wax protective material WSAQ2 with an effective concentration of 80%, and observe the stability of the self-emulsifying protective material.

Abstract

The invention discloses a self-emulsifying acrylic acid organic silicon wax protection material as well as a preparation method and application thereof. The preparation method comprises the following steps: reacting 30 to 100 parts by mass of long-chain alkyl alpha-olefin or/and long-chain alkyl monoacrylate with 100 parts by mass of polymethylhydrosiloxane in the presence of a platinum complex catalyst, cooling, adding 10 to 20 parts by mass of acrylic monomer and 2 to 20 parts by mass of nanometer MQ silicon resin, and performing heat-preservation reaction, thereby preparing the acrylic acid organic silicon wax polymer; adding ammonium hydroxide for neutralizing the polymer, thereby preparing self-emulsifying acrylic acid organic silicon wax protection material. The self-emulsifying acrylic acid organic silicon wax protection material prepared through the method is good in stability, environment-friendly, good in dispersibility, excellent in waterproof hydrophobic property and remarkable in mold stripping effect; the self-emulsifying acrylic acid organic silicon wax protection material can be used as a nursing agent, a waterproof agent, a mold stripping agent, a waterborne polymer resin additive and the like in the fields of ceramics, natural stone, concrete, metal casting, cosmetics, paint and the like.

Description

technical field [0001] The invention belongs to the field of protective materials, and in particular relates to a self-emulsifying acrylic silicone wax protective material, its preparation method and application. Background technique [0002] Ceramics and stone are two major building decoration materials in my country. Paraffin wax has low surface tension, and its performance is quite unsatisfactory in daily tile and stone care and mold release. Its water resistance, stain resistance, high temperature resistance, and durability are relatively poor, and it is only used for low-end Surface care and mold release. Silicone polymers have lower surface tension and excellent high and low temperature resistance, so silicone wax composites are widely used abroad. Many silicone waxes are waxy compounds obtained by compounding and processing long-chain alkane petroleum waxes as the basic raw materials. They are mainly oil-soluble, and because of physical compounding, there are a larg...
