Detailed Description
The present invention is further described below with reference to specific embodiments, and it should be noted that, without conflict, any combination between the embodiments or technical features described below may form a new embodiment.
The bonding resin for the continuous fiber reinforced plastic composite pipe is prepared from the following components in percentage by weight:
as a further embodiment, the polyolefin grafted silane is a polyethylene grafted silane or a polypropylene grafted silane. The polyolefin grafted silane can form adhesion to continuous fibers and a polyolefin pipe material, and silanol groups generated after hydrolysis can perform a chain extension reaction with isocyanate groups in the reactive polyurethane. The optimal dosage of the polyolefin grafted silane is 10-40%, the adhesive force to continuous fibers is insufficient when the dosage is less than 7%, the processability is influenced when the dosage is more than 45%, and excessive crosslinking is easily formed due to silanol dehydration between molecular chains to influence the adhesive property.
As a further embodiment, the reactive polyurethane is an isocyanate-terminated polyurethane prepolymer. The reactive polyurethane can form good wetting and bonding effects on continuous fibers, and can generate chain extension reaction with silanol groups formed after hydrolysis. The consumption of the reactive polyurethane is 1-10%, preferably 3-8%, the wetting property and the bonding force of the continuous fiber are insufficient when the consumption is less than 1%, the reaction group with the polyolefin grafted silane is too little, and the reaction with the polyolefin grafted silane is uncontrollable when the consumption is more than 10%, so that the premature reaction is easily caused, and the bonding of the continuous fiber is influenced.
As a further embodiment, the compatibilizer is one or any combination of ethylene-acrylate copolymer and its graft, ethylene-vinyl acetate graft, ethylene-acrylate-maleic anhydride copolymer, and ethylene-vinyl acetate-ketone carbonyl copolymer. The compatilizer can improve the compatibility and the dispersibility of the reactive polyurethane and other materials in the formula. The dosage of the compatilizer is 0.1-10%, preferably 2-5%, and when the dosage is less than 0.1%, the compatibility of the reactive polyurethane and other materials is not enough, the reactive polyurethane is easy to agglomerate, and the dispersibility is influenced; when the amount is more than 10%, the material is easily softened as a whole, and the performance of the polyolefin blend material is reduced.
As a further embodiment, the polyolefin matrix resin is polyethylene and/or polypropylene; the polyethylene is one or any combination of cross-linked polyethylene, ultrahigh molecular weight polyethylene, heat-resistant polyethylene, linear low density polyethylene, low density polyethylene and metallocene polyethylene; the polypropylene is one or any combination of homo-polypropylene, block co-polypropylene and random co-polypropylene. The dosage of the polyolefin matrix resin is 30-80%, preferably 35-75%, when the dosage is less than 30%, the polyolefin matrix resin is not well adhered to the inner and outer layer pipe materials of the composite pipe, and the adhesive resin loses the performance of the polyolefin material; the use of more than 80% means that the total of the other components is less than 20%, which causes defects such as poor adhesion to continuous fibers and poor toughness.
As a further embodiment, the elastomeric tackifying resin is one or any combination of ethylene-acrylate, ethylene-vinyl acetate, styrenic block copolymers, polyolefin elastomers, polyolefin plastomers, ethylene propylene diene elastomers, and rubbers. The elastomer tackifying resin can improve the bonding strength of the product to the continuous fibers and improve the flexibility of the product. The dosage of the elastomer tackifying resin is 5-35 percent, the best is 8-20 percent, when the dosage is less than 5 percent, the toughness of the bonding resin is easy to be insufficient, and the mechanical property, particularly the elongation at break, is low; when the amount is more than 35%, the adhesive resin is softened and the mechanical strength and stiffness of the polyolefin material are lost.
As a further embodiment, the processing anti-aging additive is a mixture of an antioxidant, inorganic nanoparticles and an ultraviolet absorbent, and the sum of the weight percentages of the antioxidant, the inorganic nanoparticles and the ultraviolet absorbent is 0.1-2%; in the bonding resin for the continuous fiber reinforced plastic composite pipe, the weight percentage of the antioxidant is 0.1-1.5%, the weight percentage of the inorganic nano particles is 0-1%, and the weight percentage of the ultraviolet absorbent is 0-0.5%. When the amount of the processing anti-aging additive is less than 0.1%, the performances of the adhesive resin such as aging resistance and the like are not good, and when the amount is more than 2%, the problems of precipitation of low molecular weight additive, yellowing of the adhesive resin and the like are easily caused.
The preparation method of the bonding resin for the continuous fiber reinforced plastic composite pipe comprises the following steps: respectively drying the weighed polyolefin grafted silane, the compatilizer, the polyolefin matrix resin, the elastomer tackifying resin and the processing anti-aging additive according to the proportion, premixing the materials by a high-speed mixer, and adding the materials into a double-screw extruder; heating the reaction type polyurethane, and adding the heated reaction type polyurethane into a double-screw extruder in an online metering and filling manner; extruding bonding resin after double-screw mixing; after multi-stage air cooling, granulating, sealing and packaging, drying in the whole process and preventing water vapor from entering; obtaining the bonding resin for the continuous fiber reinforced plastic composite pipe.
