Embodiment 1

[0011] Example 1: Preparation of emulsion nanocomposite acrylic copolymer slurry A

[0012] Weigh 5 g of sodium bentonite and add it to 85 ml of water, adjust the pH value to 8 with lye, stir and beat for 1 hour to prepare a sodium bentonite dispersion. Weigh 2.5g of acrylic acid and add it into 22ml of water, and neutralize it with 0.8g of sodium hydroxide to obtain a water-soluble mixed monomer solution; weigh 30g of butyl acrylate and 12.5g of vinyl acetate, and mix them to obtain a mixed solution of oil-soluble monomer. One-fifth of the total amount of the water-soluble mixed monomer solution and one-fifth of the total amount of the oil-soluble mixed monomer solution were added to the sodium-based bentonite dispersion, and 1g of nonylphenol polyoxyethylene ether and 0.2g of ten Sodium dialkylsulfonate, stir evenly, then add 0.5g ammonium persulfate, continue to stir and slowly raise the temperature to the reflux temperature to initiate the reaction, keep the reflux tempera...

Embodiment 2

[0013] Example 2: Preparation of emulsion nanocomposite acrylic acid copolymer slurry B

[0014] The implementation process is the same as in Example 1, except that 5g of sodium bentonite is changed into 8g of sodium montmorillonite, and 85ml of water is changed into 82ml, so that the emulsion nanocomposite acrylic acid copolymerization slurry B with a solid content of about 30% can be obtained.

Embodiment 3

[0015] Example 3: Preparation of emulsion nanocomposite acrylic copolymer slurry C

[0016] The implementation process is the same as in Example 1, except that 5g of sodium bentonite is changed into 10g of halloysite, and 85ml of water is changed into 80ml to obtain emulsion nanocomposite acrylic acid copolymerization slurry C with a solid content of about 30%.

[0017] Dilute the above-mentioned emulsion nanocomposite acrylic acid copolymerization slurry A, B and C respectively, pave a thin film, analyze with transmission electron microscope and X-ray diffraction, it can be found that the layered silicon in the slurry film of the emulsion nanocomposite acrylic acid copolymerization slurry The presence of acid salt sheets in nanometer size proves that the emulsion nano-composite acrylic copolymer pastes A, B and C prepared above are all nano-composite acrylic copolymer pastes.

Abstract

The present invention relates to fabric sizing material, and is especially one kind of environment friendly nanometer composite fabric sizing agent of acrylate copolymer emulsion and its preparation process. The fabric sizing agent comprises acrylate copolymer size and inorganic material, and has solid content of 10-50 wt%. The preparation process includes the following steps: adding clay into water and regulating pH value to form homogeneous clay dispersing liquid; compounding oil soluble monomer solution; compounding water soluble monomer solution with alkali regulated pH value; mixing clay dispersing liquid, oil soluble monomer solution, water soluble monomer solution, emulsifier and initiator via stirring; heating for copolymerization; regulating pH value and filtering to obtain product. The fabric sizing agent has simple preparation process and high performance.

Description

Technical field: [0001] The invention relates to an emulsion nano-composite acrylic acid copolymerization slurry and a preparation method thereof, in particular to an eco-friendly and environment-friendly emulsion nano-composite acrylic acid copolymerization slurry and a preparation method thereof. technical background: [0002] As we all know, textile size is mainly divided into three categories: starch size, polyvinyl alcohol (PVA) size and polyacrylic size. Since polyvinyl alcohol size was first used for warp yarn sizing in 1940, it was quickly adopted by the textile industry due to its excellent film-forming properties, adhesion and good compatibility with other sizes. After the advent of blended yarn (polyester / cotton), PVA size can also meet its sizing requirements. At present, in the sizing process of textile warp yarns, PVA has been widely used as the main size in the sizing of pure cotton, polyester cotton, polyester viscose, nylon and other yarns, and is considere...
