specific Embodiment approach 1
[0024] Specific embodiment 1: A glass fiber sizing containing carbon nanotubes described in this embodiment, the glass fiber sizing containing carbon nanotubes is composed of 0.001 to 2 parts by mass of hydroxylated carbon nanotubes, 1 part ~5 parts of surfactant, 0.005~1 part of antistatic agent, 1.5~75 parts of deionized water and 17~97.5 parts of epoxy resin emulsion system are prepared.
specific Embodiment approach 2
[0025] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is: 1. Preparation of carboxylated carbon nanotubes: impregnating carbon nanotubes in a strong oxidizing solution, at a power of 400W to 800W, and a frequency of 20kHz to 120kHz Treat in an ultrasonic instrument for 0.2h to 2h, then react in a water bath at a temperature of 40°C to 95°C for 3h to 12h, then add deionized water to dilute, cool to room temperature and filter with suction to obtain a filter residue, which is washed with deionized water and dried. Suction filtration until the pH of the washing solution is 7, and finally put the washed filter residue in a vacuum oven at a temperature of 80°C to 140°C to dry for 2h to 12h to obtain carboxylated carbon nanotubes;
[0026] The carbon nanotubes are single-wall carbon nanotubes, double-wall carbon nanotubes or multi-wall carbon nanotubes, with a diameter of 0.8 nm to 100 nm and a length of 0.5 μm to 50 μm;

specific Embodiment approach 3
[0033] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the epoxy resin emulsion system is prepared according to the following steps: when the stirring speed is 1000rpm~12000rpm and the temperature is 65°C~85 At ℃, stir and mix the epoxy resin and epoxy emulsifier evenly and add deionized water dropwise until the viscosity of the system drops. At the stirring speed of 1000rpm-12000rpm, continue stirring for 10min-100min, and then at the stirring speed of 300rpm-3000rpm Then add deionized water until the solid content of the system is 5% to 25%, to obtain an epoxy emulsion, then add an epoxy curing agent to the epoxy emulsion, and stir for 10min to 60min at a stirring speed of 300rpm to 3000rpm, Obtain epoxy resin emulsion system;
[0034] The mass ratio of described epoxy resin and epoxy emulsifier is 1:(0.05~0.2); The mass ratio of described epoxy resin and epoxy curing agent is 1000:(1~10);
[0035] The epoxy resin...

Abstract
A glass fiber sizing agent containing carbon nanotubes and a preparation method thereof, which relate to the sizing agent and its preparation method and application. The invention aims to solve the problem that the interface shear strength of the glass fiber composite material is not high after the existing sizing agent is used to treat the glass fiber. A carbon nanotube-containing glass fiber sizing agent is prepared from a hydroxylated carbon nanotube, a surfactant, an antistatic agent, deionized water and an epoxy resin emulsion system. Preparation method: 1. preparation of carboxylated carbon nanotubes; 2. preparation of hydroxylated carbon nanotubes; 3. preparation of epoxy resin emulsion system; 4. mixing to obtain glass fiber sizing agent containing carbon nanotubes. Application: The glass fiber is passed through the glass fiber sizing agent containing carbon nanotubes, and then scraped, cleaned and dried to obtain the glass fiber modified by the sizing agent. The glass fiber sizing agent containing carbon nanotubes of the present invention is mainly used for modification of glass fibers.
Description
technical field [0001] The present invention relates to a wetting agent and its preparation method and application. Background technique [0002] Glass fiber textile materials are widely used in petrochemical, architectural decoration, heat insulation and thermal insulation fields. Untreated glass fibers are very brittle and often require surface coatings to improve their properties. Different sizing agents can endow glass fibers with different properties. Untwisted coarse sand must have excellent textile properties to meet the needs of different products. Textile sizing agents can not only improve the textile properties of glass fibers, but also increase the weaving properties of glass fiber cloth. strength. Sizing raw materials and formulation technology are the most critical elements for manufacturing high-quality glass fibers, and they are also an essential part of the glass fiber production process. It is vividly compared to "chip manufacturing technology" in the ind...
