Abstract
The invention discloses novel skis which are composed of composite material cores, poly(p-phenylene benzobisoxazole) fiber (PBO)-enhanced bottom boards and surface layers, wherein the bonding strength of the PBO fibers treated by epoxy resin is obviously enhanced, and the surface layers are formed by compounding carbon fibers and polyethylene. The bottom boards prepared by the PBO-enhanced polyethylene treated by epoxy resin are light in weight, good in mechanical property and good in elasticity; and the strength, toughness, environmental stress crack resistance, impact strength, cold endurance and the like of the skis are well improved by adopting the linear low density polyethylene.
Description
Technical field
The present invention relates to a kind of preparation method of Novel skiing board, the preparation of its base plate belongs to field of polymer composite material, and final prepared product is skis equipment making field.
Background technology
The material of skis and by material all more complicated, for many years, resistance between the reduction planing surface of skis and snow face, the lightweight of skis, improve the damping performance of skis, improve the endurance of skis and turnability, and improve the electric conductivity of skis, prevent from sliding electrostatic effect cause skis absorbs impurity and affect the problems such as speed always pay close attention to by people.
Technical problem to be solved by this invention is, utilize after the pretreated PBO of epoxy resin (EP) and LLDPE merge, obviously can strengthen the elasticity of LLDPE, restore to the original state after being conducive to its distortion, improve its turnability.
Summary of the invention
Research purpose of the present invention is to solve skis in use because distortion causes skis overall performance to reduce, and then causes base plate and snowfield contact area to reduce, the problem that resistance increases.
In order to realize the object of foregoing invention, solving skis problem in actual applications, the invention provides following technical scheme:
(1) with epoxy resin (EP) by adding curing agent and pbo fiber prepares EP/PBO fiber through HTHP;
(2) after the pbo fiber processed by epoxy resin (EP) and LLDPE merge, thinly slice as skis bottom, bond with inner core after adding hot extrusion and prepare composite bottom board, thickness is 1.5mm, long 155cm, wide 30cm;
(3) with fibre reinforced composite polyethylene material for superficial layer, simultaneously add carbon fiber and carbonic acid material in surperficial end positions, to reach maximum twisting resistance and bending property;
(4) polythene material of foaming is cut into slices according to the thickness needed for skis, as the inner core of skis
(5) inner core is positioned on base plate, Pressurized-heated, keeps 15 ~ 20min, make composite bottom board;
(6) composite bottom board prepared in ski surface layer prepared in above-mentioned steps (6) and step (5) is carried out compoiste adhering, carry out edge pruning according to required form, obtained finished product skis product.
(7) the invention has the advantages that: skis prepared by the method for the invention, main body uses material to be polythene material, lightweight, fine corrosion resistance, the sole of ski adopted is made up of the composite merging through the pretreated PBO of epoxy resin (EP) and LLDPE, significantly improve the problem on deformation of skis, be conducive to the service life extending skis, thus reach the effect of economize energy and material.
Detailed description of the invention
The preparation method being a kind of special fibre and strengthening sole of ski set forth in the present invention.The method comprises the following steps:
1. skis described in this patent, its agent structure is by bottom, and inner sandwich layer and superficial layer three part form.
2. the superficial layer of skis described in this patent, it prepares material is carbon fiber reinforced composite polyethylene material;
3. the inner core version of skis described in this patent is be prepared into composite with polyethylene foamed after the process of viscose foundation stone ink fiber prepreg stain, obtained after section.
4. the bottom of skis prepared of this patent, forms by merging through the pretreated PBO of epoxy resin (EP) and LLDPE.
5. in this patent, composite bottom board is heated to 120 DEG C, is positioned in mould and carries out pressurized treatments, and pressurization pressure is 1010 ~ 1012Pa, and keeps 5 ~ 15min;
6. whole its advantage of invention product is lightweight, fine corrosion resistance, prepared sole of ski forms by merging through the pretreated PBO of epoxy resin (EP) and LLDPE, improve skis in use owing to being out of shape the problem of the skiing performance of skis and the skiing service life reduction caused, make obviously increase by more than 5% the service life of skis.
