Description
Technical field
The present invention relates to outdoor sports equipment technical fields, and in particular to a kind of rotational moulding surfboard.
Background technology
Surfboard is that people are used for the sports equipment that moves of surfing, using wave as power, using the showmanship of itself and
Balanced capacity, fights with one of wave movement, user stand on a surfboard or using web, kneel plate, inflation rubber
Pad, canoe, kayak etc. control an aquatic sports of wave, and the movement is deep by people due to fabulous and can take exercises
Like, surfboard must could be used by the thrust of stormy waves, and surfboard can just show surfing only when stormy waves is big
Show its unique charm, whens moderate seas can plow it is sleeping float thereon waterborne, enjoy the leisure enjoyment of natural fluctuation, initially use surfing
Plate grows five meters or so, and 50-60 kilograms of weight, as people’s lives level improves, people are increasing to surfboard demand, should
Under the premise of its processing efficiency is ensured, ensure its quality and beauty again.
Under the conditions of existing surfboard impregnates in water and the sun is exposed to the sun, easily discoloration and fade, at the same occur leak, into
Water phenomenon threatens personal safety, and toughness, shock resistance, resilience, the property fallen are poor at low temperature for existing surfboard in addition, to surfing
Movement brings certain restrictions.
Invention content
The purpose of the present invention is to provide a kind of rotational moulding surfboard, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical solution：
A kind of rotational moulding surfboard, including surfboard ontology, the surfboard ontology outermost layer is equipped with PE shells, outside the PE
Shell is fixedly connected with PU layer of polyurethane, and PU layer of polyurethane is connected with froth bed；The PE upper surface of outer cover is equipped with object placing cavity, outside PE
Shell upper surface object placing cavity side, which is equipped with, brews mouth on foam, and PE shells lower surface object placing cavity opposite side is equipped with and brews mouth under foam.
It is as further scheme of the invention：The PE shells are that environmentally friendly LLDPE material rotational moulding is integrally formed.
It is as further scheme of the invention：Protection and beautiful pattern layer are additionally provided on the PE shells.
It is as further scheme of the invention：Spring, spring upper end and surfboard sheet are equipped in the surfboard ontology
Body upper surface is fixedly connected, and lower spring end is fixedly connected with surfboard ontology lower surface.
It is as further scheme of the invention：The object placing cavity is concave structure, and the object placing cavity depth is 5-
7cm。
It is as further scheme of the invention：The PE upper surface of outer cover is additionally provided with knob.
It is as further scheme of the invention：The PE shells are equipped with face of trampling, and the face of trampling is equipped with anti-
Sliding line and anti-skidding cam, and anti-skidding cam is set along face edge is trampled.
It is as further scheme of the invention：The anti-skid chequer number is multiple.
Compared with prior art, the beneficial effects of the invention are as follows：This kind of rotational moulding surfboard watertightness is good, high-low temperature resistant is subzero
55 DEG C -70 DEG C, shock resistance, high tenacity, high resilience, anti-dropping capability is very good, and -55 DEG C of low temperature can meet safety standard
Fall requirement, it is indeformable will not more split it is broken；The degree of adhesion that PE shells are combined it with polyurethane foams is stronger, for a long time in water
In and the sun be exposed to the sun later all be not in be detached from separation, it is seen that its degree of adhesion becames one completely with PE shells, makes product
Intensity higher, toughness is more preferable, and either high temperature or low temperature all keep original color, it is not easy to change and fade, use the longevity
Life length.The present invention has the advantages that reasonable in design, high tenacity, high resilience, service life is long, and surfing is suitble to use.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
It please refers to Fig.1 and Fig. 2, in the embodiment of the present invention, a kind of rotational moulding surfboard, including surfboard ontology 1, the surfing
1 outermost layer of plate ontology is equipped with PE shells 2, and the PE shells 2 simultaneously will by PE shells 2 in foaming mould by low-temperature heat
Environment protection chemical gas is connected with PU layer of polyurethane 3 under the conditions of being filled with 2 inner core of PE shells, and the PU layer of polyurethane 3 is connected with
Froth bed 4,2 upper surface of PE shells are equipped with object placing cavity 5, and 2 upper surface object placing cavity of PE shells, 5 side is equipped with and brews mouth 6 on foam,
2 lower surface object placing cavity of PE shells, 5 opposite side is equipped with and brews mouth 7 under foam；After heating after a period of time and filling gas, then will
Surfboard inner core is squeezed into PU filling polyurethane agent, by it full of foam, foam is made to flow to each orientation corner all in plastics inner
Can filling in place, dead angle will not all be let off, and the foam that this method can reach 2 inner core of PE shells enriches full, while its is interior
The generation for phenomena such as portion's foam is also not in stomata, deformation.
Protection and beautiful pattern layer 8 are additionally provided on the PE shells 2, pattern layer 8 can both play beauty function, also may be used
With anti-skidding effect, personal safety is protected in surfing.
Spring 9 is equipped in the surfboard ontology 1, plays cushioning effect.
The object placing cavity 5 is concave structure, and object placing cavity 5 can place article.
2 upper surface of PE shells is additionally provided with knob 10.
The PE shells 2 are that environmentally friendly LLDPE material rotational moulding is integrally formed.
The PE shells 2 are equipped with face 11 of trampling, and the face 11 of trampling is prevented equipped with anti-skid chequer 12 and anti-skidding cam 13
Sliding cam 13 is set along 11 edge of the face of trampling, and antiskid effect is played in surfing, and described 12 numbers of anti-skid chequer are multiple.
Color masterbatch, UV resistant agent and stabilizer are additionally added in the environmental protection LLDPE material, LLDPE material good weatherability,
Adding in UV resistant agent and stabilizer simultaneously can make rotational moulding surfboard high temperature or low temperature all keep original color, not variable
Color and colour fading, service life was up to 20 years.
The environment protection chemical gas be a kind of novel filling gas, have special one-component composition, can completely by
Environment protection chemical gas is attached to the core surface of PE shells 2, and environment protection chemical gas is filled, and is equivalent to the core surface of PE shells 2
The effect of one layer of alite paste is coated, this gas can make both PE shells 2 and PU layer of polyurethane 3 that can preferably be glued
Attached property, makes them not detached with reference to after, is all not in for a long time to be detached from separation in water and after the sun is exposed to the sun, it is seen that
