Example Embodiment

[0036] Example 1:

[0037] The mass percentage of each component of the high-performance nano-modified acrylic slurry adopts acrylic acid: acrylamide: acrylonitrile: butyl acrylate: oleic acid: nano-sized titanium dioxide (particle diameter is 30 nanometers) = 20: 25: 12: 31: 3 : 9 (the masses are: 18 grams of acrylic acid, 22.5 grams of acrylamide, 10.8 grams of acrylonitrile, 27.9 grams of butyl acrylate, 2.7 grams of oleic acid, 8.1 grams of nano-scale titanium dioxide). The manufacturing steps are as follows:

[0038] The first step: raw material pretreatment

[0039] (1) Prepare 100 ml each of 10% NaoH solution and 10% Nacl solution;

[0040] (2) Wash the acrylic monomer with 10% NaoH solution and 10% Nacl solution to remove the polymerization inhibitor;

[0041] (3) Dissolve 22.5 g of acrylamide in 50 g of water first, and then mix the pretreated other monomers with it to form a monomer mixture.

[0042] The second step: modification of nano titanium dioxide

[0043] (1) Tur...

[0058] Example 2: The mass percentage of each component of the high-performance nano-modified acrylic slurry is acrylic acid: acrylamide: acrylonitrile: butyl acrylate: oleic acid: nano-sized titanium dioxide (particle diameter is 30 nanometers) = 24: 29: 10 :28:2:7 (the mass is 21.6 grams of acrylic acid, 26.1 grams of acrylamide, 9 grams of acrylonitrile, 25.2 grams of butyl acrylate, 1.8 grams of oleic acid, 6.3 grams of nano-grade titanium dioxide).

[0059] The manufacturing steps and processes are the same as in Example 1. The difference from Example 1 is that in addition to the different components mentioned above, the amount of ammonia water (30% concentration) added is 52.5 grams, so that the PH value of the synthetic solution is 7;

[0061] Example 3:

[0062] The mass percentage of each component of the high-performance nano-modified acrylic slurry adopts acrylic acid: acrylamide: acrylonitrile: butyl acrylate: oleic acid: nano-sized titanium dioxide (particle diameter is 30 nanometers) = 22: 27: 11: 29: 2.7 : 8.3 (the mass is 19.8 grams of acrylic acid, 24.3 grams of acrylamide, 9.9 grams of acrylonitrile, 16.1 grams of butyl acrylate, 2.43 grams of oleic acid, and 7.47 grams of nano-grade titanium dioxide).

[0063] The manufacturing steps are the same as in Example 1. The process is different from Example 1 as follows:

[0064] (1) Titanium dioxide swells for 55 minutes;

[0065] (2) After the monomer and initiator are added dropwise, slowly increase the temperature of the liquid in the reactor to 90°C and keep it basically stable for 60 minutes;

[0066] (3) In addition to the different quality of the components mentioned above; when the temperature is lowered to 65°C, 57.5g of ammonia water (concentratio...

Abstract

The present invention belongs to the field of new polymer material, and discloses one kind of nanometer modified high performance acrylic acid size and its preparation process. The acrylic acid size is prepared with nanometer level titania powder, acrylic acid, acrylamide acrylonitrile and butyl acrylate as main synthesized material, oleic acid as modifier and ammonium sulfate as initiator. Owing to the nanometer material with reinforcing effect, wear resistance and high permeability, and the acrylic acid monomer with functional group similar to that in fabric fiber structure, the size has excellent permeating and coating performance and high adhesion, forms complete, antiwear, tough and elastic size film, and may be used in sizing fabric of cotton, Dacron, etc. including fabric warp with high density and high weaving difficulty.

Description

Technical field: [0001] The invention belongs to the field of polymer materials, and relates to a high-performance nano-modified acrylic slurry and a manufacturing method thereof. Background technique: [0002] Due to the general acrylic paste, its paste performance mainly depends on the performance of each organic monomer. Specifically, due to the combination of different monomers, the molecular structure of the synthetic slurry has different functional groups, which make it have certain polarity, hydrophilicity and glass transition temperature; but due to the defects of various monomers, the synthetic slurry The sizing film strength and abrasion resistance of the material are still poor, and the excessive amount can easily cause the sizing yarn to absorb moisture and stick again. Therefore, the sizing effect is not ideal, and it cannot completely replace PVA. It can only be used in conjunction with PVA and starch to assist in sizing. PVA is an unclean slurry, which has b...
