Description
Technical field
The present invention relates to linen fiber composite plates material and preparation technology thereof, be specifically related to a kind of have anti-flaming function carbon fiber and linen fiber composite plates material and manufacturing process.
Background technology
Along with improving constantly and the enhancing of consumer health, awareness of safety of social economy's level, people are when pursuing car conour and power, also more and more pay close attention to function, the aesthetic feeling of automotive trim, comfortableness, and the smell of automotive interior material, environmental protection and health hazard problem.Natural ramie fiber because have inexpensive, light weight, can natural degradation, the excellent properties such as specific strength and specific stiffness height, therefore as reinforcing material, be widely used in the Design and manufacture of polymer-based composite.Patent documentation (publication number CN 101045310A) discloses linen fiber composite plates material and processing method thereof for a kind of automotive trim, with flaxen fiber, polypropylene fiber, polyster fibre, make sandwich layer and surface layer, through lapping, acupuncture, become compound numb felt, then it is molded to pass through warm-up mill.Patent documentation (publication number: CN 101549671A) disclose a kind of fibrilia automobile inner decoration member and production method thereof, use tossa and polypropylene fiber to be combined into felt, then numb felt is directly carried out in baking oven to Baking out and surperficial bonding, then through product mold, carry out cold moudling.Select fiber and flaxen fiber that some mechanical properties are more excellent to be used in conjunction with, can further improve intensity and the toughness of composite, meet the mechanical mechanics property of auto parts and components and the requirement of security performance.Patent documentation (publication number CN 102145553A) discloses a kind of flaxen fiber and basalt fibre composite board and production method thereof, this sheet material is usingd flaxen fiber and basalt fibre as main reinforcement, adopt heat pressing process moulding, there is the features such as quality is light, intensity is high, good toughness, security height.Patent documentation (publication number CN 103101261A) adopts more excellent carbon fiber and the compound composite board of making of flaxen fiber of mechanical property, overcome the performance deficiency of single linen fiber composite plates material, the feature such as product has that density is little, intensity is high, good toughness, mouldability, safe, nontoxic, environmental protection.Above-mentionedly take the equal Shortcomings part of composite board that flaxen fiber is main reinforcement, main problem is incendive natural ramie fiber not carry out flame treatment, in production, storage, use procedure, there is potential safety hazard, limited to a certain extent its application on automotive upholstery.
Summary of the invention
It is not good that one of the object of the invention is to solve the flame retardant effect of above-mentioned flaxen fiber composite, has the problem of certain combustion safety, and a kind of have anti-flaming function carbon fiber and linen fiber composite plates material are provided.
Two of the object of the invention is to provide a kind of carbon fiber and linen fiber composite plates manufacture process with anti-flaming function.
For realizing the object of the invention, adopt following scheme: carbon fiber and the linen fiber composite plates material with anti-flaming function are comprised of sandwich layer and surface layer; Natural ramie fiber after described sandwich layer is processed by fire retardant, chopped carbon fiber and three kinds of fiber mixing lapping acupunctures of flame-retardant polypropylene fibre are made, and the percentage by weight of each component is: carbon fiber 10%～30%, flaxen fiber 20%～50%, flame-retardant polypropylene fibre 30%～40%; Described surface layer is made by flame-retardant polypropylene fibre and two kinds of chemical fibre batch mixing lapping acupunctures of flame retardant polyester fiber, and the percentage by weight of each component is: flame-retardant polypropylene fibre 40%～70%, flame retardant polyester fiber 30%～50%.
Fire retardant is the FR-PN-B liquid flame retardant that the gloomy halogen-free smoke resistance flame resistance agent of Shanghai rising sun Co., Ltd produces, and solid content is 25%; The amount ratio of flaxen fiber and liquid flame retardant is 1:1.
Carbon fiber and the linen fiber composite plates manufacture process with anti-flaming function, comprise following four manufacturing steps:
The first step: flaxen fiber is carried out to flame treatment
Flaxen fiber and FR-PN-B liquid flame retardant are pressed 1:1 consumption, at room temperature flaxen fiber is placed in FR-PN-B liquid flame retardant and floods 30min～60min, after taking out with padding machine roll compacting to remove unnecessary fire retardant, repeat above-mentionedly to soak-roll process 2 times～4 times, then at 120 ℃, be dried to constant weight;
Second step: prepare sandwich layer
According to each component of sandwich layer and weight proportion thereof, first the flaxen fiber after flame treatment, chopped carbon fiber and flame-retardant polypropylene fibre are carried out to shredding processing, then mix, be finally paved into fleece acupuncture and make carbon fiber and flaxen fiber composite felt material;
The 3rd step: prepare surface layer
According to each component of surface layer and weight proportion thereof, first flame-retardant polypropylene fibre and flame retardant polyester fiber are carried out to shredding processing, then mix, be finally paved into fleece acupuncture and make composite felt material;
The 4th step: manufacture carbon fiber and the linen fiber composite plates material with anti-flaming function
First the two-sided of sandwich layer second step being obtained fitted with the surface layer of the 3rd step acquisition respectively, through the pre-heat treatment, then puts into together in hot pressing die, and one-step mould obtains carbon fiber and the linen fiber composite plates material with three-decker and anti-flaming function.Wherein the temperature of the pre-heat treatment is 200 ℃～250 ℃, and the time of the pre-heat treatment is 60s～120s, and hot-forming molding pressure is 15MPa～20MPa, and the compression molding time is 60s～120s.
The present invention is helpful to be: when introducing carbon fiber lifting composite materials property, emphasis is not good for the flame retardant effect of flaxen fiber composite, there is certain combustion completion hidden danger, design and manufacture a kind of anti-flaming function carbon fiber linen fiber composite plates material that has, quality is light, intensity is high except having for this sheet material, the feature of good toughness and asepsis environment-protecting, flame-retarding height is the large feature of this composite one, can be used for the manufacture of the various inside gadgets of automobile.
