Problems solved by technology
[0003] Nano-calcium carbonate has excellent filling and reinforcing properties, but its surface energy is high, and the surface is hydrophilic and oleophobic, while the surface of polyolefin is non-polar. When the two are blended, the surface is incompatible, and nano-calcium carbonate is prone to agglomeration Therefore, the performance of nano-calcium carbonate is reduced, so nano-calcium carbonate is usually modified
In the prior art, during the production process of the nano-calcium carbonate polypropylene composition material, a large amount of agglomeration still occurs, which cannot meet the needs

Embodiment Construction
[0011] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0012] The manufacturing process of the first embodiment of the nano-sterilizing cloth of the present invention includes the following steps: first, the nano-calcium carbonate is subjected to surface modification treatment: take the carbonized nano-calcium carbonate with an average particle diameter of 120 nanometers and a concentration of 50 grams per liter 20 liters of slurry, adjust the pH value to 10, heat up to 80 ° C, then add 10 liters of triethanolamine borate solution with a concentration of 5 grams per liter, and stir for 1.5 hours to react; precipitate and filter the calcium carbonate slurry. Dry at 80°C to remove moisture, and borate-modified nano-calcium carbonate can be obtained.

The invention discloses a manufacturing process of a nano sterile fabric, which comprises the following steps: 1, carrying out surface modification on nano calcium carbonate; 2, mixing 50 parts of nano calcium carbonate by weight after surface modification with 0.1 part of antioxidant by weight and 1 part of polyethylene wax by weight in a high-speed mixer at a high temperature of 120 DEG C for 5 minutes; 3, adding 0.5 part of polypropylene-grafted maleic anhydride by weight, 1 part of nano titanium dioxide-loaded silver ion antibacterial by weight and 50 parts of acrylic resin by weight to the high-speed mixer, mixing for 5 minutes; 4, squeezing out the well mixed materials, and granulating to obtain a nano calcium carbonate-polypropylene composition; 5, manufacturing the nano calcium carbonate-polypropylene composition into a processed fabric; and 6, laminating a non-woven fabric and the processed fabric to obtain the nano sterile fabric. The invention brings the performance of the nano calcium carbonate into full play, and the use on water purifying equipment can improve the water-purifying effect.
Description
technical field [0001] The invention relates to a manufacturing process of a nano-sterilizing cloth, in particular to a manufacturing process of a nano-sterilizing cloth applied to water purification equipment. Background technique [0002] Using nanotechnology and materials to transform traditional polymer materials is a hot research topic at home and abroad. Nano-calcium carbonate is a widely used inorganic filler that can be used in polyethylene and polypropylene products. Due to its small particle size, nano-calcium carbonate High surface activity, compared with traditional calcium carbonate, when it is used in polyolefin products, it has little effect on the overall performance of the material, and in some cases, it can even improve the performance of the material in some aspects, such as tensile strength , impact strength, etc. [0003] Nano-calcium carbonate has excellent filling and reinforcing properties, but its surface energy is high, and the surface is hydrophil...
