Description
Technical Field
The invention relates to the technical field of continuous fiber reinforced thermoplastic composite materials, in particular to a preparation method and equipment of a pressure-sensitive continuous fiber reinforced resin prepreg tape.
Background
Various fiber-reinforced resin composite materials are gradually replacing traditional metal materials, and are widely applied to various fields requiring light weight, including various vehicles such as airplanes and automobiles. With the application development of the fiber reinforced thermoplastic composite material, the continuous fiber reinforced thermoplastic material impregnated belt is gradually popularized due to the excellent physical characteristics and various processing and forming modes. The method is widely applied to a plurality of fields such as transportation, civil and military aviation, petrochemical industry, sports equipment, building materials and the like. The purposes of light product weight, high strength, corrosion resistance, recyclability and convenient processing and forming are achieved, and due to the excellent comprehensive performance, the industry is developed vigorously.
In recent years, a flexible Reinforced Thermoplastic composite pipe (RTP pipe for short) is a high-pressure plastic composite pipeline, has the characteristics of good flexibility, corrosion resistance, high pressure resistance, impact resistance, wear resistance, light weight, easiness in connection, coiling, long-distance joint-free quick laying and the like, can well overcome the corrosion problem of a steel pipe and the pressure resistance problem of a plastic pipeline, and can be applied to the field of petroleum and natural gas exploitation, high-pressure long-distance natural gas transportation and various pipelines requiring high-pressure transportation media. After being put into use for the first time in the United kingdom in 6 months since 1995, the RTP pipe is applied to an oil and gas field as an oil and gas gathering and transmission pipeline in a large amount, and is rapidly popularized in other fields as a corrosion-resistant and high-pressure-resistant long-distance transmission pipeline, such as the fields of urban pipe networks, natural gas transmission, chemical industry and the like.
In the winding process of the prepreg tape, the prepreg tape is firstly required to be heated and melted, and then the prepreg tape is rotated by a certain angle to increase the number of layers of the layers through self winding, so that the reinforced thermoplastic composite pipe with excellent reinforcing effect is obtained. High temperature melting can result in loss of performance of the prepreg reinforcing effect and can present challenges to process control and cost control. The wettability of the glass fiber in the resin is greatly influenced by the thickness of the final prepreg tape, and the difficulty in controlling equipment and the process in the cooling process of the ultra-thick prepreg tape from the molten state is greatly improved. Some researchers have made related attempts to address these issues. Although the thickness of the prepreg tape produced by the existing molten resin infiltration process at one time can be barely achieved, the infiltration between glass fibers and resin of the prepreg tape prepared by the method is extremely poor, so that the tape generates dry yarns and other defects, and the comprehensive performance of the product is finally reduced. Another disadvantage of this method is that it has high requirements for cooling equipment and difficulty in process control, which can easily result in untimely cooling of the wetting tape, thereby increasing the crystallinity of the polymer and causing severe shrinkage of the wetting tape. Another attempt is to use the currently used thermal compounding process, which uses two or more layers of the finished prepreg tape to be heated by the heating rollers of the thermal compounding machine, and the prepreg tape between the upper and lower heating rollers of the thermal compounding machine is heated and melted to be bonded together to prepare an ultra-thick prepreg tape. The method has obvious defects that the prepreg tape between the upper heating roller and the lower heating roller is heated to extend from the outside to the inside due to the fact that the prepreg tape is melted by the heating rollers of the thermal compound machine, so that the prepreg tape needs to be integrally melted to effectively thermally melt and bond the contact surfaces of the two layers of prepreg tapes. Thus, the original linear distribution of the fibers of the prepreg tape itself under the pressure of the hot press roll is disturbed to form an irregular curved shape. This fiber arrangement will undoubtedly have a negative effect on the mechanical properties of the final prepreg tape.
The continuous fiber reinforced resin composite material has the advantages that the fibers and the resin are effectively fused, the continuous fibers are uniformly distributed along the width direction of a product, and particularly, the difficulty of effective fusion of the fibers and the resin is increased when a common hot-melt resin process is adopted to produce the continuous fiber reinforced resin composite material strip with the super-thick size. The effective fusion degree of the fiber and the resin is a key characteristic index for evaluating the physical performance of the mechanical continuous fiber reinforced tree composite material strip of the product in a sticking and connecting manner. In other preparation process technologies, for example, a secondary hot-melting composite processing technology is adopted, two layers of continuous fiber reinforced tree composite material strips which need to be connected with each other are heated to a molten state, and the ultra-thick continuous fiber reinforced tree composite material strips which are overlapped and connected into a whole in thickness are manufactured; the defects of the process technology are that when two layers of continuous fiber reinforced resin composite material strips which are mutually attached are heated to a molten state, the change of resin and fiber is easily caused, and the mechanical properties of the ultra-thick continuous fiber reinforced resin composite material strips are influenced. For example, chinese patent CN104669647A in the QY patent discloses a process and an apparatus for preparing a continuous fiber reinforced thermoplastic composite material, which adopts a traditional double extrusion casting process and an on-line compounding process to prepare a thickened tape. The defect is that the content of the upper layer and the lower layer can not be controlled, so that the strength between the prepreg tape layers is unstable. And because the double-extrusion system adopted in the design process causes large equipment investment and waste of spatial arrangement. Therefore, the above problems need to be solved in the design and processing of the high-strength ultra-thick continuous glass fiber reinforced thermoplastic impregnating material.
The CN105346200A patent of Shanxi Tian's policy new material science and technology Limited company adopts the cured thermoplastic resin film to be directly compounded with continuous fibers through a hot pressing roller, in the process, the poor infiltration effect of the thermoplastic resin on the continuous fibers is caused due to the poor fluidity of the thermoplastic resin and the poor hot melting effect of the hot pressing roller, and the problems of poor infiltration effect, poor interface effect and low material strength of the continuous fiber reinforced thermoplastic resin composite material are directly caused, and the process is limited by the size shrinkage of the thermoplastic film in the heating process, and the uniform distribution of the product resin is difficult to ensure; and a secondary process of reheating the resin film is adopted, and the economy is poor and the cost performance of the product is not high.
The invention provides a preparation process and a flow of a continuous fiber reinforced thermoplastic composite material with a pressure-sensitive adhesive film layer on the surface, in particular to a combined design of a hot-melt resin extrusion die head and a resin smearing guide roller, and provides a better solution for the preparation process and the flow of the super-thick continuous fiber reinforced thermoplastic composite material by selecting a resin with a melting point lower than the melting point temperature of the resin of the prepared continuous fiber reinforced resin composite material needing thickness superposition as a material for sticking a connecting layer.
At present, aiming at a pressure-sensitive continuous fiber reinforced resin prepreg tape, a device and a method which are simple to operate in the manufacturing process and can effectively improve the product quality are urgently needed to be designed.
