Embodiment 1

[0043] Embodiment 1: Carding the carbon fiber felt or bundles, so that there is a certain space between the carbon fiber monofilaments, which are relatively monofilament-like independent, and then placed in an upright diameter of 200mm. The inner wall is coated with a silicone-coated circular tube-shaped container middle. The water-based polyurethane emulsion (PU) with a solid content of 10% is atomized with a gas compression atomizer, and the droplet diameter is 0.1-3um to become an aerosol, and the aerosol is described from a circular tube with an air flow rate of 20L / min. Introduced at the bottom of the container to coat the carbon fibers. After 15 minutes, take out the coated carbon fiber, dry it at room temperature for 3 days, and then use it.

[0044] Use a fluorescence microscope to observe the microscopic condition of the carbon fiber surface coating, and take pictures, as shown in Figure 2, the composite coating is in the shape of joints.

[0045] The treated and dr...

Embodiment 2

[0046] Embodiment 2: The carbon fiber mat or bundle is kept in a certain space between each carbon fiber, and then placed in a vertical tube container with a diameter of 200 mm and an inner wall coated with silicone coating. The styrene-acrylic emulsion with a solid content of 10% is atomized with a gas compression atomizer, and the droplet diameter is 0.1-3um. The aerosol is introduced from the bottom of the circular tube with an air flow rate of 20L / min, and the carbon fiber is coated. cover. After 15 minutes, take out the coated carbon fiber, dry it at room temperature for 3 days, and then use it.

[0047] Use a fluorescence microscope to observe the microscopic condition of the carbon fiber surface coating, and take pictures, as shown in Figure 3, the composite coating is in the shape of joints, and the bulge is not uniform.

[0048] The treated and dried carbon fibers were prepared according to the preparation method of the single-fiber cement sample, and the fiber embed...

Embodiment 3

[0049] Embodiment 3: The carbon fiber mat or bundle is kept in a certain space between each carbon fiber, and then placed in a vertical silicone-coated pipe with a diameter of 200 mm. The EVA emulsion with a solid content of 10% is atomized with a gas compression atomizer, the droplet diameter is 0.1-3um, and the aerosol is introduced from the bottom of the circular tube with an air flow rate of 20L / min to coat the carbon fiber. After 15 minutes, take out the coated carbon fiber, dry it at room temperature for 3 days, and then use it.

[0050] Use a fluorescence microscope to observe the microscopic condition of the carbon fiber surface coating, and take pictures, as shown in Figure 4, the composite coating is in the shape of joints, and the bulge is dense but not obvious.

[0051] The treated and dried carbon fibers were prepared according to the preparation method of the single-fiber cement sample, and the fiber embedding length was 2.5mm, and cured for 7 days at 20°C and RH...

Abstract

Asphalt modified carbon fiber modification of chaotic accumulation and its production methods and equipment belong to the field of asphalt modified carbon fiber modification. Its character is that coat water-soluble polymer emulsion composite coating at the surface of carbon fiber. The composite coating carbon fiber has the characters that: solid, with high intensity, simple structure of equipment, adopt the method of atomizing air polymer emulsion to modify the surface of chaotic accumulated asphalt modified carbon fiber, Technique is simple, reliable, environmental protection, energy conservation, the effect of significantly modified, increase effectively the bonding power of asphalt carbon fiber in the cement, expand the scope of use for the asphalt carbon fiber.

Description

technical field [0001] The invention relates to the modification of pitch carbon fiber with random accumulation and its production method and equipment, and the invention belongs to the field of pitch carbon fiber surface modification. Background technique [0002] Carbon fiber has excellent properties such as high specific strength, high specific modulus and corrosion resistance, and its composite materials have been widely used in aviation, aerospace, sports equipment, road transportation, construction and other fields. Carbon fiber is a graphite crystal layer structure oriented along the fiber axis. Its surface is smooth, its surface energy is low, and it is inert. Therefore, when carbon fiber reinforced cement and polymer resin are used to make composite materials, the bond between carbon fiber and matrix material The performance is poor, which is manifested by the low interfacial bonding strength of the composite material, which affects the use of the composite material...
