Definitions
- the invention belongs to the technical field of natural fiber composite materials and wood plastic composite materials, and particularly relates to a plastic reinforcing hemp fiber and a preparation method thereof
- Natural plant fibers are formed by long-fiber or braided fiber mats and then thermoformed with thermosetting resins. They cannot be directly added to thermoplastics for injection molding like glass fibers.
- natural plant fibers are rich in hydroxyl groups on the one hand. , showing strong polarity and hydrophilicity, poor compatibility with non-polar or weakly polar plastics, poor performance of prepared composites; on the other hand, due to the large volume of plant fibers, large filling capacity, fibers and The large friction between plastics, fibers and equipment and fibers makes plant fiber reinforced plastics difficult to process, especially for injection molding.
- interface compatibilizer In order to solve the problem of compatibility between plant fiber and plastic interface, the main solution at present is to add interface compatibilizer, one type is coupling agent, such as silane coupling agent, titanate coupling agent, aluminate coupling. Agent, rare earth coupling agent, The isocyanate coupling agent and the like, and the other is a graft or copolymer of maleic anhydride and a polyolefin. Most of the coupling agents are used in small amounts of liquid and are not easily dispersed uniformly in plant fibers, affecting the coupling effect. Industrial applications require special equipment to handle; grafts or copolymers of maleic anhydride and polyolefin are mostly particles.
- Another object of the present invention is to provide a method for producing the above-mentioned plastic reinforcing hemp fiber.
- a hemp fiber for plastic reinforcement consists of the following components by weight:
- Hemp fiber treatment agent 0.1 to 100 parts (preferably 10 to 80 parts)
- the short cut hemp fiber is one or more of ramie fiber, flax fiber, sisal fiber, jute fiber, and hemp fiber.
- the hemp fiber treating agent is a urea-formaldehyde resin prepolymer, a trimethylol melamine resin or a hexamethylol melamine resin.
- the functional polyolefin is a metallocene polyethylene wax, a metallocene polypropylene, a metallocene polyolefin, an oxidized metallocene polyolefin wax, and a metallocene polyolefin wax. More than one of maleic anhydride grafts.
- the coupling agent is one or more selected from the group consisting of a silane coupling agent, a titanate coupling agent, an aluminate coupling agent, an isocyanate coupling agent, and a rare earth coupling agent.
- the antioxidant is an antioxidant 1010 and an antioxidant 168, and the mass ratio of the two is 2:1.
- the above method for preparing a plastic reinforcing hemp fiber comprises the following steps:
- Step (1) The mass percentage concentration of the aqueous sodium hydroxide solution is 1% to 10%
- the mass percentage concentration of the hemp fiber treatment agent aqueous solution is 10% to 50%; the dry water is dried by centrifugation; the drying is air drying to a mass moisture content of 8 to 15% (Normal moisture content of hemp fiber).
- Step (1) The drying is performed by vacuum drying, and the drying temperature is 90 to 150. °C, the mass moisture content of the dried to hemp fiber is less than 1%; the rinse with water is washed to pH 7.0 ⁇ 9.0.
- Step (2) the stirring time is 5 to 10 minutes; the stirring speed is 50 to 300 per minute. Turn.
- the principle of the invention is: the invention washes off impurities on the surface of the fiber by using a dilute alkali solution, and then uses urea - Water of a treatment agent such as a formaldehyde resin prepolymer, a trimethylol melamine resin or a hexamethylol melamine resin Solution treatment, the hydroxyl group on the surface of the fiber reacts with the methylol group of the treating agent, and the surface of the fiber is coated with a layer of urea-formaldehyde resin or melamine resin, which reduces the surface polarity of the hemp fiber, reduces the water absorption rate of the hemp fiber, and improves the water absorption rate.
- the rigidity and heat resistance of the hemp fiber; the compatibility of the hemp fiber with the plastic is further improved by the coupling agent, and the lubricity and dispersibility of the fiber interior are improved by the functional polyolefin.
- the short cut hemp fiber prepared by the invention has good color, good rigidity and heat resistance, and can be directly added into the plastic matrix like the short glass fiber, and the phase with the plastic. It has good capacitance and can be used to prepare high-performance short hemp fiber/plastic composite material and play an enhanced role in the plastic matrix.
