Summary of the invention
The object of the invention promptly is to provide a kind of later-model High molecular material crossbeam rim strip and manufacture craft thereof, both can use new material replacing wood chock, and it is good to reach structural strength, the purpose of long service life.
High molecular material crossbeam rim strip provided by the present invention has the strip body that High molecular material is made, and it is characterized in that spaced apart taper circular hole is arranged on the body, and the groove of perforation is arranged at the body bottom; Described High molecular material proportioning (by weight) is: India rubber, 50 parts; Buna-S, 20 parts; The high-tenacity reclaimed rubber, 500 parts; Strong prestige powder, 100 parts; Protection wax, 1.2 parts; Zinc oxide, 5 parts; Stearic acid, 2 parts; Precipitated calcium carbonate, 200 parts; Antioxidant 4010NA, 2 parts; Carbon black N330,100 parts; Third fractional oil, 60 parts; Captax, 4.5 parts; Sulphur, 7 parts; The fabric fibre powder, 150 parts.
The manufacture craft of the disclosed High molecular material crossbeam of the present invention rim strip is characterized in that, comprises the steps:
1) sizing material processing:
Step 1-1, plasticate: two roller mill roll spacings are transferred to 1 millimeter, and start idle running 5~10 minutes is respectively plasticated buna-S, India rubber 8~10 times, parks for use;
Step 1-2, the fabric fibre powder preparation: fabric is put into mill, and rod utilizes the mill shearing force with its fragmentation apart from transferring to 1.5 millimeters, and the container of putting into appointment is for use;
Step 1-3; Mixing: as will to drop into together in the hopper of Banbury mixer through buna-S, India rubber and the fabric fibre powder of over-mastication; And add zinc oxide, precipitated calcium carbonate, strong prestige powder, high-tenacity reclaimed rubber, stearic acid, captax, antioxidant 4010NA, carbon black N330, third fractional oil, sulphur, protection wax successively; Carry out banburying, take out after 3~5 minutes;
Step 1-4, thin logical: will pass through mixing sizing material and approach logically with two roller mills, roll spacing transfers to 0.5 millimeter, approaches to lead to 5~6 times, again roller is transferred to 5 millimeters, and following sheet is for use;
Step 1-5, Mold Making:, make corresponding mould according to outer glue shape and size;
Step 1-6, production: use vulcanizing press, preheated mold, temperature are 150~160 ℃, and the adjustment sulfide stress is 10~12MPa, add film, matched moulds, presulfurization moulding 6 minutes, delivery, cleaning overlap.
The present invention's disclosed High molecular material crossbeam rim strip and manufacture craft thereof; Use High molecular material replacing wood chocks such as rubber; Thereby the fine problems such as consuming a large amount of timber that solved in the above-mentioned Automobile manufacturing, and through product structure design is improved has further improved the performances such as friction durability, compression support of product; Alleviate the deadweight of product simultaneously, reduced the cost of manufacturing materials.
The specific embodiment
Shown in accompanying drawing, High molecular material crossbeam rim strip provided by the present invention has the body 2 that High molecular material is made, and is strip, can confirm its length according to the vehicle needs.Spaced apart some taper circular holes 1 are arranged on the body 2, play the effect of segment bearing, expendable weight, energy-absorbing buffering.The groove 3 of perforation is arranged at the body bottom, through the whole length range of body, has the effect of containing fastening bolt, enhancing damping effect, reduction product gross weight, practicing thrift cost.The section of groove 3 can be an arc, also can be trapezoidal or square, is best with the arc.
Above-mentioned High molecular material proportioning (by weight) is: India rubber, 50 parts; Buna-S, 20 parts; The high-tenacity reclaimed rubber, 500 parts; Strong prestige powder, 100 parts; Protection wax, 1.2 parts; Zinc oxide, 5 parts; Stearic acid, 2 parts; Precipitated calcium carbonate, 200 parts; Antioxidant 4010NA, 2 parts; Carbon black N330,100 parts; Third fractional oil, 60 parts; Captax, 4.5 parts; Sulphur, 7 parts; The fabric fibre powder, 150 parts.
Wherein, natural gum can adopt No. 3 smoke sheet rubbers of Thailand's import; Styrene butadiene rubber sbr 1723 is by Qilu Petrochemical production; The fabric fibre powder is to be made up of poly-ester fibres, polyster fibre, vinylon fibre, cotton fiber etc.; It can be a kind of or any 2~4 kinds combination wherein; Be filled in the raw MAT'L of the present invention, as the framework material of High molecular material crossbeam rim strip provided by the present invention.In addition; Above-mentioned fabric fibre powder also can utilize goods such as waste and old sebific duct, adhesive tape and production thereof to add the leftover bits that produce in the process to be raw material; Add speed ratio and be in 1: 1.17 the mill, apart from transferring to 1.5 millimeters, utilize the mill shearing force on rod its broken getting final product.
