Description
Technical field:
The present invention relates to a kind of rubber weather strip.Be specifically related to a kind of preparation method of New Marine rubber weather strip.Belong to the product of rubber and plastic technical field.
Background technology:
Marine rubber sealing strip is mainly used in boats and ships door and window and other occasion, seals.Its cross-sectional structure is composited by grooved epidermis 1 and sponge core 2 as shown in Figure 1.What its preparation method adopted is the ripe sponge of bark, promptly is with revulcanization composite molding behind epidermis and the sponge core difference sulfidization molding.Its concrete preparation method is as follows:
One, epidermis is made
Epidermis is made referring to Fig. 2:
A) sizing material is mixing---and the sizing material that will make epidermis places mixer mixing to become compound,
B) be extruded into material base---place screw extrusion press to be extruded into material base compound,
C) molded vulcanization moulding---place the moulding of vulcanizing press molded vulcanization to make the grooved epidermis material base,
D) surface finish---with the inner bottom surface and the two medial surfaces decorticating mill surface finish of grooved epidermis,
E) coating adhesive---at the inner bottom surface coated with adhesive of grooved epidermis, standby.
Two, the sponge core is made
The sponge core is made referring to Fig. 3:
A) sizing material is mixing---and the sizing material that will make the sponge core places mixer mixing to become compound,
B) be extruded into material base---place screw extrusion press to be extruded into material base compound,
C) molded vulcanization moulding---place the moulding of vulcanizing press molded vulcanization to make the foam sponge core material base,
D) park typing---the foam sponge core is parked for some time, make its typing,
E) surface finish---with the bottom surface and the two sides decorticating mill surface finish of foam sponge core,
F) coating adhesive---at the bottom surface of foam sponge core coated with adhesive, standby.
Three, sealed strip is made
Sealed strip is made referring to Fig. 4:
A) vulcanize the seat end, bottom---and the sponge core that will foam places in the groove of epidermis, is placed on and makes composite sulfuration moulding between epidermis inner bottom surface and the foam sponge core basal surface in the vulcanizing press, take out,
B) coating adhesive---at two medial surfaces of epidermis groove and the equal coated with adhesive of two outer sides of sponge core,
C) two sides sulfuration---epidermis is placed the vulcanizing press post cure together with the foaming sponge core in it, make between foam sponge core two outer sides and epidermis groove two medial surfaces compoundly, make the sealed strip work in-process, taking-up,
D) coating adhesive---with the two sides head compound place strip off of sealed strip half-finished foaming sponge core and epidermis groove, behind the reaming once more at both strip off position coated with adhesive,
E) knot face, surface sulfuration---preceding road epidermis is placed vulcanizing press knot face, surface sulfuration once more together with the sponge core in it, make the sealed strip finished product.
This shows that this preparation method's complex manufacturing needs could finally make the sealed strip finished product through five sulfurations, secondary polishing, four gluings and a peeling, production efficiency is low, energy consumption height, production cost height.And the length of finished product is subjected to the restriction of the dull and stereotyped length of vulcanizing press, need repeatedly splice epidermis and sponge core in the production process, has reduced production efficiency of products so again.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, the preparation method of the low New Marine rubber weather strip of a kind of production efficiency height, energy consumption and production cost is provided.
The object of the present invention is achieved like this: a kind of preparation method of New Marine rubber weather strip is characterized in that this method comprises following processing step:
Step 1, epidermis are made
A) sizing material is mixing---and place mixer mixing to become compound sizing material,
B) be extruded into material base---place screw extrusion press to be extruded into material base compound, standby;
Step 2, sponge core are made
A) sizing material is mixing---and place mixer mixing to become compound sizing material,
B) be extruded into blank---place screw extrusion press to be extruded into material base compound, standby;
Step 3, sealed strip are made
A) the seat end---sponge core material base is placed in the groove of epidermis material base,
B) sulfidization molding---epidermis material base and sponge core material base are placed drying tunnel together, the epidermis material base is vulcanized and closely composite molding together with the sponge core material base in it, make the sealed strip finished product.
The preparation method of New Marine rubber weather strip of the present invention, 80 ℃～180 ℃ of described drying tunnel temperatures, 2～5 meters/min of speed, curing time 1～8 hour.
This shows, what the inventive method adopted is that rawhide is given birth to sponge sulfuration composite molding technique, production technique is simple, only need just can make the sealed strip finished product through sulfidization molding of drying tunnel, No. four vulcanizing press sulfurations, secondary polishing, four gluings and a peeling technology have been save, production efficiency can improve 30%, and energy consumption reduces by 40%, and production cost descends 30%.Extended the again simultaneously length of finished product, promptly the length of finished product can be arranged to the length of drying tunnel.Can enhance productivity so again.
