Description
Technical field
The present invention relates to a kind of structure of sheet material, particularly relate to a kind of skateboard body structure.
Background technology
From the end of the fifties in last century, slide plate plate face has experienced the common plank being fixed on iron tyre from, to multilayer oak floor, the spanning development of lightweight maple plate etc., skateboarding also develops into all over the world from the U.S. gradually, slide plate is in the starting stage in China, but on market, major part is all more traditional plate face, can be shock-resistant, good springiness, safety, slide plate that durability is lasting be still more rare.
Most of plate faces are 7～9 laminates, are glued together with 7～9 layers of thin plate.Some company claims that their plank is very light, and this has used thinner plank mostly, or the number of plies still less, or makes thin plate intersect gummed.These methods make plate face light a little, but they make slide plate fragile a little equally.Some company even adds the pin nest of more layer or increasing plate to increase the durability of plate.
Some company is in the different way of the textural employing of plate face or innovation.Such as, " New Wave Construction " patented technology of Flip company, on plank surface, adding the undulatory runner of last layer increases the performance of plate face.Real company has adopted " Triple Beam Construction ", has used 7 layers of glued board, and wherein 3 layers is to intersect gummed.This makes the elasticity of plank and durability have a larger increase.
In addition also have other innovation, if patent CN103157267A is at skateboard body laminating whole piece high strength fibre, but can not make fiber be dispersed in completely uniformly whole plate face, unbalance stress, shock resistance is limited.
Patent CN2836870Y adds carbon fibre composite sheet at slide plate plate face, but carbon fiber toughness or elasticity are poor, can make the hardening of plate face, and have the sharp outstanding of hard in wearing and tearing or breaking part, directly contact with the fiber of exposure once user, may cause the allergic or swollen bad reaction such as itch.
Although patent CN201040175Y pushes down fibre reinforced layer by ring, mid portion or direct and extraneous contact, inevitably can wear and tear in use procedure and reduce service life and result of use.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of light, safe, durable, environmentally friendly skateboard body structure.
A kind of skateboard body, from bottom to up successively by lightweight plank layer, p-aramid fiber enhancement layer and frosted layer three-decker are composited, wherein, described lightweight plank layer and described p-aramid fiber enhancement layer adopt colds pressing or hot pressing mode straight forming, described p-aramid fiber enhancement layer bottom surface is provided with mucigel, is bonded and fixed on described lightweight plank layer, and described frosted layer is bonded and fixed on described p-aramid fiber enhancement layer.
Skateboard body of the present invention, wherein said lightweight plank layer adopts hard maple.
Skateboard body of the present invention, wherein said p-aramid fiber enhancement layer is formed by p-aramid fiber braiding, and described p-aramid fiber intensity is greater than 19.5cN/dte, and modulus is 85～110GPa, and percentage elongation is 2.5～4.0%; Described p-aramid fiber thread count is 66*54～150*150 root/10cm, and weight is 100～260g/m
2.
Skateboard body of the present invention, wherein said frosted layer adopts dry abrasive paper, and described dry abrasive paper surface sand grains particle diameter is between 10～40 μ m.
A kind of slide plate, described slide plate comprises skateboard body of the present invention.
Skateboard body difference from prior art of the present invention is:
Skateboard body of the present invention adopts three-Tier Model, lightweight plank layer can effectively reduce plate body weight, cold-press process is more advanced, performance is better, p-aramid fiber enhancement layer dispersibles the horizontal and vertical load-bearing that on slide plate, user of service produces slide plate, make the load-bearing of plate face entirety, prevent local overload and make the fracture of plate face, make plate mask have high-strength impact toughness and good elasticity, frosted layer can increase plate face frictional force, is convenient to control slide plate, can protect p-aramid fiber enhancement layer simultaneously, also can cut out easily, on sand paper, make various logo or individualized pattern; Described dry abrasive paper is the one of sand paper, and particle diameter is larger, and frictional force is large; Skateboard body of the present invention is light, safe, durable and belong to environmentally friendly.
Skateboard body of the present invention also tool has the following advantages:
(1) described lightweight plank layer adopts the maple sheet materials such as Canadian maple, Russian maple or Northeast China maple, become multiple thin slices through preprocessing, pass through cold-press process, need not add binder directly compresses wood chip, more advanced, performance is better, makes plate mask have high-strength impact toughness and good elasticity.
(2) described p-aramid fiber enhancement layer employing p-aramid fiber is raw material, and described p-aramid fiber intensity is greater than 19.5cN/dte skateboard body, and modulus is 85～110GPa, and percentage elongation is 2.5～4.0%; Thread count is 66*54～150*150 root/10cm, and weight is 100～260g/ ㎡, dispersibles the horizontal and vertical load-bearing that on slide plate, user of service produces slide plate, makes the overall load-bearing of plate face, prevents local overload and makes the fracture of plate face.
P-aramid fiber is a kind of high performance organic polymer fiber, has intensity high, good toughness, and modulus is high, and density is low, corrosion-resistant, the advantages such as Heat stability is good, hot strength can reach 23cN/dtex, and elongation at break is 2.0～4.0%; There are Dupont, Japanese Supreme Being people, Korea S Cologne in external manufacturing enterprise and know star, domestic industry enterprise is mainly Yantai Tayho Advanced Materials Co., Ltd. and Suzhou megadyne Te Xian scientific & technical corporation, wherein the safe green wood in Yantai was realized kiloton industrialization in 2011, have at present tandem product, had ripe application in national defence, optical cable, automobile and other industries.
