Field of the invention The present invention relates to the formation of discontinuous fiber reinforced plastics and a method for facilitating the impregnation of discontinuous fibers with rubber compounds and the treatment of discontinuous fibers with a coupling agent. The resulting impregnated discontinuous fibers can be used to reinforce a variety of plastics. 2. Description of the known technology Printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs ^ ----------, installed-(Please read the precautions on the back before filling this page) Most of the Plastic products are used in plastics with good fiberglass as a reinforcing material. However, glass fibers are quite expensive, which increases the cost of manufacturing plastic products reinforced with glass fibers. Glass fibers are formed by heating the glass to a molten state and guiding the molten glass through a nozzle, while at the same time rapidly pulling or thinning the molten glass into thin continuous fibers. A group of individual continuous fibers or monofilaments is then passed through a water sprayer and through an applicator that provides a protective coating or size, and the fibers are then gathered into a bundle or strand. Continuous fibers can be drawn through the glue tank in nature, on rollers with coatings, or between rollers, and at the same time achieve further fiber elongation. The impregnated fibers are then glued together by a rubber compound and wound around a roll in a bundle of 2000 to 2000 fibers. These fiber strands can be woven into glass fiber textiles, laid into nonwovens, cut to a size between 6 and 25 mm (millimeters) 'or processed into fiber pieces of random length. Because the fiber is pre-impregnated, its surface is bonded to plastic. Therefore, these different fiber products are better reinforcements for plastics. However, the conventional technology does not include the product of the present invention and the size of the paper used in the Chinese National Standard (CNS) A4 (2 丨 〇 X 297 mm) -4-A7 B7 V. Description of the invention (2) method, where The discontinuous fibers are impregnated with a rubber compound and a coupling agent, and the resulting impregnated fibers form plastic reinforcing fibers that overcome the disadvantages of the discontinuous fibers. The plastic produced by impregnating discontinuous fibers of the present invention can replace glass fiber reinforced plastics at a greatly reduced cost and without requiring any type of clear and transparent plastic. According to the invention, the purpose of the present invention is to transform discontinuous fibers into fiber products that can be used as plastic reinforcing materials and to provide a novel method for achieving this. The method is based on thorough impregnation and compression molding using sizing and coupling treatment to convert Normally, loose fiber masses turn dense enough to flow freely in a feeding device 'and dense enough to easily mix with plastic in the form of a pallet. Another object of the present invention is to provide a method for manufacturing discontinuous fiber-reinforced plastics, wherein the discontinuous fibers form a slurry, which is laid on a horizontally moving screen to become a wet plate or thin material to separate the liquid material from the slurry. Part of the dried slurry on the screen is then passed through an upright press where the coupling agent is added. Printed by the Consumer Standards Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs Another purpose of the present invention is to provide a method as defined in the previous objective 'where the rubber compound can be attached to discontinuous fiber slurry and has a drying process before an upright press' The size can be added to the wet sheet before the first dryer. The coupling agent is attached to the partially dried sheet ' at or immediately before the standing press to maintain the integrity of the sheet. After the vertical press, there is a second drying and thin material compression process, so that the compressed and dried thin material sent from the mobile screen can be shredded into strips to be fed to the compound together with the plastic pallet -5- ( Please read the notes on the back before filling this page.) This paper size is applicable to Chinese National Standard (CNS) A4 (210X297 mm) B7 V. Description of the invention (3) Forming reinforced plastic products in the machine or extrusion machine, or The compressed and dried sheet can be laminated with the plastic sheet to form a fiber-reinforced plastic panel. The discontinuous fibers in the strip or sheet form a longitudinal, transverse, or various angular relationship to other fibers, and increase the strength characteristics of the strip or sheet of plastic reinforced fiber in the longitudinal and transverse directions. The entire area of a plastic article formed from a shredded strip or sheet provides relatively constant strength characteristics. These, along with other purposes and advantages that will become apparent later, exist in the structure and operation details of the drawings described more fully and requested with reference to the drawings which become a part thereof, where the same numbers indicate the same components.
