Abstract
The present invention discloses a kind of preparation method of cellulosic tubing, includes following steps: (1) prefabricated block foam powder; (2) plastic interlayer is wrapped up in; (3) fiber cloth is rolled up; (4) curing molding; (5) from mould, finished product is taken out.By, by the shape first preparing tubing needed for basis, foam powder is produced a block foam powder identical with pipe geometry, then plastic interlayer is wrapped up in successively, volume fiber cloth and curing molding, instead of the mode loading foaming powder toward fibre pipe of tradition, so make block foam powder be heated evenly to expand and form interior pressure from inside and fiber cloth is bulged be close to die cavity internal face and shape, stop foam powder easily overflow and occur burning into sand, or foam powder hollow and occur the appearance of the forming defects such as false connection, effectively improve shaping yield, and above-mentioned preparation method implementation and operation is easy, operating efficiency improves greatly.
Description
Technical field
The present invention relates to racket art, refer in particular to a kind of preparation method of cellulosic tubing.
Background technology
At present, the preparation method of known cellulosic tubing is: first select fiber cloth to roll into a hollow fiber conduit; Then, in this fibre pipe, the powder that foams in right amount is loaded; Then, the fibre pipe that foaming powder is housed is inserted in mould and heated, makes this fibre pipe solidifying and setting, in the process of heating, this foaming powder expanded by heating and form interior pressure from inside and fiber cloth is bulged be close to die cavity internal face and shape; Finally, tubing is taken out from mould.
Although, said method can realize the making of cellulosic tubing, but, use said method in manufacturing process, in fibre pipe, foaming powder is directly loaded because it uses, the distribution of foaming powder is scattered, make in heating process, foaming powder in fibre pipe can not expand equably and act on fibre pipe and fibre pipe is shaped, thus foam powder is easily overflowed and occurs burning into sand, or foam powder hollow and occur false connection etc., the above-mentioned forming defect being tubing, result in shaping yield lower, and also there is the low problem of operating efficiency in above-mentioned preparation method.
Summary of the invention
In view of this, the present invention is directed to the disappearance of prior art existence, its main purpose is to provide a kind of preparation method of cellulosic tubing, and its preparation method that effectively can solve existing cellulosic tubing exists the problem that shaping yield is low, operating efficiency is low.
For achieving the above object, the present invention adopts following technical scheme:
A preparation method for cellulosic tubing, includes following steps:
(1) prefabricated block foam powder, produces a block foam powder identical with pipe geometry according to the required shape preparing tubing by foam powder;
(2) plastic interlayer is wrapped up in, at least one plastic film interlayer of block foam powder outer wrapping;
(3) roll up fiber cloth, select fiber cloth and fiber cloth wrapped plastic interlayer formation semi-finished product tubing;
(4) curing molding, inserts aforementioned semi-finished product tubing in mould and heats, heating process in, this block foam powder be heated evenly expand and formed from inside interior pressure fiber cloth is bulged be close to die cavity internal face sizing and form finished product;
(5) from mould, finished product is taken out.
As a kind of preferred version, described block foam powder loads in plastic film bag and forms aforementioned plastic film layer outward at block foam powder.
As a kind of preferred version, described fiber cloth is carbon fibre materials.
As a kind of preferred version, the heating-up temperature of described mould is 150 DEG C ± 5 DEG C, and the heat time of mould is between 20 minutes ~ 35 minutes.
The present invention compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution:
By the shape first preparing tubing needed for basis, foam powder is produced a block foam powder identical with pipe geometry, then plastic interlayer is wrapped up in successively, volume fiber cloth and curing molding, instead of the mode loading foaming powder toward fibre pipe of tradition, so make block foam powder be heated evenly to expand and form interior pressure from inside and fiber cloth is bulged be close to die cavity internal face and shape, stop foam powder easily overflow and occur burning into sand, or foam powder hollow and occur the appearance of the forming defects such as false connection, effectively improve shaping yield, and above-mentioned preparation method implementation and operation is easy, operating efficiency improves greatly.
For more clearly setting forth architectural feature of the present invention and effect, below in conjunction with accompanying drawing and specific embodiment, the present invention is described in detail.

Detailed description of the invention
Please refer to shown in Fig. 1 to Fig. 7, that show the concrete structure of the preferred embodiment of the present invention, include following steps:
(1) prefabricated block foam powder 10, to produce a block foam powder 10(identical with pipe geometry as shown in Figure 1 according to the required shape preparing tubing by foam powder).
(2) plastic interlayer 20 is wrapped up in, at at least one plastic film interlayer of block foam powder 10 outer wrapping 20(as shown in Figure 2), in the present embodiment, this block foam powder 10 loads at the aforementioned plastic film layer 20 of the outer formation of block foam powder 10 in plastic film bag, not to be limited.
(3) roll up fiber cloth 30, select fiber cloth 30 and fiber cloth 30 is wrapped plastic interlayer 20 and form semi-finished product tubing (as shown in Figure 3), in the present embodiment, this fiber cloth 30 is carbon fibre materials, but is not limited to carbon fibre materials.
(4) curing molding, as shown in Figure 6, aforementioned semi-finished product tubing is inserted in mould 40 and heat, the heating-up temperature of this mould 40 is 150 DEG C ± 5 DEG C, the heat time of mould 40 is between 20 minutes ~ 35 minutes, heating process in, this block foam powder 10 be heated evenly expand and formed from inside interior pressure fiber cloth 30 is bulged be close to die cavity 41 internal face sizing and form finished product (as shown in Figure 7).
(5) from mould 40, finished product is taken out.
Design focal point of the present invention is: by the shape first preparing tubing needed for basis, foam powder is produced a block foam powder identical with pipe geometry, then plastic interlayer is wrapped up in successively, volume fiber cloth and curing molding, instead of the mode loading foaming powder toward fibre pipe of tradition, so make block foam powder be heated evenly to expand and form interior pressure from inside and fiber cloth is bulged be close to die cavity internal face and shape, stop foam powder easily overflow and occur burning into sand, or foam powder hollow and occur the appearance of the forming defects such as false connection, effectively improve shaping yield, and above-mentioned preparation method implementation and operation is easy, operating efficiency improves greatly.
The above, it is only preferred embodiment of the present invention, not technical scope of the present invention is imposed any restrictions, thus every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
