Abstract
The invention discloses a method for preparing a super-hydrophobic carbon fiber fabric and relates to a method for preparing a carbon fiber fabric. The invention aims to provide a method for preparing a superhy-drophobic carbon fiber fabric which is covered with a thin layer of polyperfluoralkylsiloxane on the surface. The method comprises the following steps of: soaking a carbon fiber fabric into a perfluoralkylsiloxane solution; and then airing, repeating 2 to 5 times and drying to obtain the super-hydrophobic carbon fiber fabric. The invention realizes the superhydrophobicity of the surface of the carbon fiber fabric by utilizing the method for coating a hydrophobic substance (perfluoralkylsiloxane) on the macroscopical rough surface of the carbon fiber fabric. The prepared super-hydrophobic carbon fiber fabric can be used as a main building material for manufacturing a small ship and a submarine and used as an outer-layer coating material for being coated on the outer surface of the ship and the submarine.
Description
Technical field
The present invention relates to a kind of preparation method of carbon fibre fabric.
Background technology
Carbon fiber is a kind of new material of mechanical property excellence, and its proportion is less than 1/4 of steel, and carbon fiber resin composite material tensile strength all more than 3500Mpa, is 7～9 times of steel generally, and tensile modulus of elasticity is that 23000～43000Mpa also is higher than steel.Therefore the specific strength of CFRP is that the ratio of intensity and its density of material can reach more than the 2000Mpa/ (g/cm3), and the specific strength of A3 steel only is about 59Mpa/ (g/cm3), and its specific modulus is also than steel height.The specific strength of material is higher, then member dead weight is littler, specific modulus is higher, then the rigidity of member is bigger, indicated the broad prospect of application of carbon fiber in this sense in engineering, take a broad view of the excellent properties of multiple emerging composite (as polymer composite, metal-base composites, ceramic matric composite), many people expect, the human epoch that just entering into a composite extensive use on material is used from the iron and steel epoch.
Carbon fiber can be processed into fabric, felt, seat, band, paper and other materials.Carbon fiber does not generally use separately except that as the heat-insulating material, how to join in the materials such as resin, metal, pottery, concrete as reinforcing material, constitutes composite.The carbon fibre fabric reinforced composite materials can be used as aircraft construction material, electromagnetic shielding and removes health substitute material such as electric material, artificial ligament and be used to make rocket envelope, power ship, industrial robot, leaf springs of car and driving shaft etc.
Because the graphite-like structure of carbon fiber surface causes its surface energy low.This makes with the other materials binding ability not good, often need carry out surface modification before use.Yet low surface prepares one of essential condition of super hydrophobic material just.
Summary of the invention
The objective of the invention is preparation method for the super-hydrophobic carbon fibre fabric that the poly-perfluoroalkyl siloxanes of a kind of surface coverage skim is provided.
The preparation method of the super-hydrophobic carbon fibre fabric of the present invention is as follows: one, will be by weight percentage by 0.1%～8% perfluoroalkyl siloxanes, 1%～10% water, 1%～10% acid, mixed solution sonicated 30min～120min that all the other are formed for ethanol forms the perfluoroalkyl siloxane solution; Two, carbon fibre fabric is immersed 10s～60s in the perfluoroalkyl siloxane solution, dry then; Three, repeating step is 2 2～5 times; Four, will dry 3h～12h at 80 ℃～150 ℃ through the carbon fibre fabric that step 3 is handled, promptly get super-hydrophobic carbon fibre fabric; The siloxanes of perfluoroalkyl described in step 1 chemistry general formula is CF

3, wherein the span of n is 2～200, the span of m is 1～200; Acid is glacial acetic acid, hydrochloric acid or sulfuric acid described in the step 1; Carbon fibre fabric described in the step 2 is carbon fibre fabric bundle, carbon fibre fabric cloth, carbon fibre fabric felt or carbon fibre fabric three dimensional fabric.
Space in the carbon fibre fabric of the present invention between the fibre bundle is not more than 900 microns, has guaranteed that water can not leak down at carbon fiber surface.
This patent is maximized favourable factors and minimized unfavourable ones, and in the plurality of advantages of performance carbon fibre fabric, also brings into play the low characteristics of its surface energy that is considered to " shortcoming ".The present invention utilizes the method that applies lyophobic dust (perfluoroalkyl siloxanes) on the roughness surface of carbon fibre fabric macroscopic view itself to realize the super-hydrophobic of carbon fibre fabric surface.Prepared super-hydrophobic carbon fibre fabric can be used as main construction material and is used to make spitkit, submarine, and puts on a suit of armour material as skin and put on a suit of armour outer surface with boats and ships, submarine.Adopt boats and ships, the submarine of super-hydrophobic carbon fibre fabric manufacturing to have light weight, running resistance is little, stealthy under water, bearing capacity is big, corrosion resistant characteristics.The boats and ships of putting on a suit of armour super-hydrophobic carbon fibre fabric have equally that little, the stealthy ability of underwater navigation resistance is strong, bearing capacity is big, corrosion resistant characteristics.
