[0004] The higher price of organic fluorine resins makes the application of organic fluorine resins subject to many restrictions. There have been extensive research and applications on organic fluorine-modified acrylate resins or emulsions, organic fluorine-modified epoxy resins, etc., and reduce the organic fluorine. The cost of application, but in commonly used plastics, such as polyethylene resin, polypropylene resin, polycarbonate resin, nylon resin, ABS resin, etc., the modification of organic fluorine is almost blank. The patent of the present invention discloses an organic fluorine An effective way to modify plastic products

example 1

[0018] Example 1 Polypropylene plastic is cheap and one of the most widely used plastics. Superhydrophobic polypropylene plastic has broad application space in biotechnology, medical equipment and other fields. However, superhydrophobic polypropylene plastic with high cost performance is basically in the market. Blank, according to the method disclosed in the patent of the present invention, design and manufacture a cost-effective superhydrophobic polypropylene plastic, which is used in the manufacture of biological reagent tubes. It has good anti-fouling, anti-blood contamination performance and inert to biological reagents. The method includes the following steps:

[0019] 1) Prepare perfluoropentane pentyl acrylate by polycondensation of perfluoropentane and pentyl acrylate;

[0020] 2) According to 15% perfluoropentane pentyl acrylate, 15% silica powder mixture, 70% polypropylene resin, plus 1% chlorinated paraffin, 1% stearic acid, in the temperature range of 220 degrees ...

example 2

[0022] Example 2 Although polyvinyl fluoride and polyvinylidene fluoride have super-hydrophobic properties, the higher market price hinders the wide application of these polyvinyl fluorides. According to the method disclosed in the patent of the present invention, a cost-effective super-hydrophobic Polyethylene plastic is used in the manufacture of medical films and has good waterproof and anti-fouling properties. Its manufacturing method includes the following steps:

[0023] 1) Prepare perfluorobutane butyl acrylate by polycondensation of perfluorobutane and butyl acrylate;

[0024] 2) According to 15% perfluorobutane butyl acrylate, 15% silica powder mixture, 70% polypropylene resin, plus 1% chlorinated paraffin, 1% stearic acid, in the temperature range of 220 degrees to 250 degrees Inside, a twin-screw extrusion granulator is used to manufacture perfluorobutane butyl acrylate polyethylene masterbatch;

[0025] 3) Add 2% of the above-mentioned perfluorobutane butyl acryla...

Abstract

The invention discloses a manufacture method for super-hydrophobic plastic. The manufacture method comprises the following steps: 1) performing condensation reaction of perfluoroalkane (including but not limited to perfluorobutane, perfluoropentane and perfluorohexane) and acrylic ester to get perfluoroalkyl acrylate; 2) mixing the silicon dioxide having three particle sizes (10-30 nanometer, 200-500 nanometer and 800-1200 nanometer) in mass ratio of 1:1:1 uniformly; 3) preparing the material: by mass, 15% of condensation compound of perfluoroalkyl acrylate, 15% of mixture of silicon dioxide, 70% of plastic resin (including but not limited to polyethylene resin PE, polypropylene resin PP, polycarbonate PC, polyamide PA, ABS resin and the like), 1%-5% of paraffin or chlorinated paraffin as an internal lubricant, and 1%-3% of stearic acid as an external lubricant, stirring fully to make the material mix uniformly; 4) manufacturing composite master batch by a extrusion moulding method in a double screw extruder at the temperature of 220-280 DEG C; 5) manufacturing various plastic products by using a extrusion, rolling process, injection moulding, spray, blow molding and so on.

Description

technical field [0001] The invention patent relates to the fields of chemistry and material science such as material design, organic synthesis, material modification, and organic polymer composite material manufacturing. Background technique [0002] Adding various components to polymer resins to form new mixtures or new polymer resins by physical or chemical methods, and then manufacturing products through injection molding technology is a widely used polymer material modification technology. [0003] By reducing the surface energy of the material and increasing the surface contact angle of the material, the material can obtain superhydrophobic properties. In practical applications, the material has good waterproof and anti-fouling properties. [0004] The higher price of organic fluorine resins makes the application of organic fluorine resins subject to many restrictions. There have been extensive research and applications on organic fluorine-modified acrylate resins or em...
