The invention is characterized in that the calendering rubber sizing material on the single or both side of the cotton cloths is proceed on a four-roller calender, the running speed of the calender is 3 to 5 meters per minute and the calendering temperature is 70 to 100 DEG C.
Description
Technical field
The present invention relates to a kind of blanket production technology, specifically is the technique for producing air cushion printing blanket on the offset press printing roller.
Background technology
Blanket on the existing offset press printing roller, all be four layers of plastic structure of four layers of cloth: its surface glue, hose lining and foaming layer all adopt the steam rubbing method to finish; Specifically be on every layer of cotton, to apply rubber slurry using and, as shown in Figure 2 with four layers of compound and sulfuration of cotton that scribbles rubber slurry using, afterwards blanket is carried out grinding then with the Steam Heating oven dry.This technology had both been wasted solvent (dimethylbenzene or toluene) and steam, contaminated environment, and inefficiency again.
Summary of the invention
Technical problem to be solved of the present invention provides a kind of improvement of printing blanket production technology, and this production technology should be able to overcome the deficiency of above-mentioned background technology, has the characteristics of production efficiency height, good product quality, energy savings, also helps environmental protection.
The technical solution used in the present invention is: a kind of technique for producing air cushion printing blanket may further comprise the steps successively:
1) to the cotton single face coating rubber rubber cement and the oven dry of superficial layer, rubber size is rolled on the two sides of remaining intermediate layer cotton simultaneously; Bottom cotton single face calendering rubber size;
2) each layer cotton of coating rubber and calendering rubber size is superimposed afterwards directly compound on two roller compounding machines;
3) blanket after compound is vulcanized;
4) after the sulfuration blanket is carried out grinding.
It is to carry out on four-roll calender that rubber size is rolled on cotton single face calendering rubber size or cotton two sides simultaneously.
The speed of a motor vehicle of described four-roll calender be 3-5 rice/minute, rolling temperature is 70-100 ℃.
The printing blanket of explained hereafter provided by the invention, its most cotton adopts the mode of calendering rubber size, and has given up existing coating mode of heating, has tangible energy savings effect.Adopt roller calendering rubber, used solvent can significantly reduce (reducing 70%--80%), the corresponding minimizing of drying time (reducing 70%--80%); Not only save solvent and steam consumption, reduced consumption, reduced production cost, improved production efficiency, and significantly reduced the volatilization (volatilization of solvent during oven dry) of solvent, helped environmental protection.
Description of drawings
Fig. 1 is the schematic diagram of the present invention to every layer of cotton calendering rubber size.
Fig. 2 is the combination process schematic diagram of air cushion rubber and cloth.
Fig. 3 is the schematic diagram of existing technology coating rubber rubber cement on every layer of cotton.
The specific embodiment
The production technology of existing air cushion printing blanket is as shown in Figure 3: (small circle is represented the cross section of cotton parallel to cotton 5, wave is represented the cotton warp) be pulled travel forward (direction of motion of cotton is arrow M) on the open and flat conveyer belt that drives at roller 6 (clear for drawing, conveyer belt omits and do not draw); The stagnant upper surface of rubber slurry using 9 (rubber size adds the certain amount of solvent stirring and forms) at cotton, a scraper plate that dangles 10 keeps the thickness of certain spacing with the control rubber cement with cotton; Use the Steam Heating steam pipe in addition, the hot-air direct baking of being distributed (the hot-air direction is represented with arrow N) is in the lower surface of cotton, so that heating is with the upper surface rubber slurry using oven dry of cotton.Obviously, steam consumption is bigger in this technology, and solvent evaporates during the rubber that applies oven dry, and environment is impacted.
The present invention with above-mentioned process modification is:
1) (among the present invention, the intermediate layer cotton has 2 layers at the two sides of intermediate layer cotton calendering rubber size; Rubber size is rolled on the two sides of every layer of cotton respectively); Concrete operations can be carried out on four-roll calender.Specifically as shown in Figure 1: the gap between the top a pair of roller (roller 1 and roller 3) has determined the thickness of cotton upper surface rubber size, when this relatively rotates roller rubber mass 2 is rolled into certain thickness glue-line 2-1; Below gap between a pair of roller (roller 11 and roller 12) determined the thickness of cotton lower surface rubber size, when this relatively rotates roller rubber size 13 rolled into certain thickness sizing material layer 13-1.When cotton 5 passed (direction is an arrow A) between roller 3 and roller 11 (keeping 70-100 ℃ temperature), sizing material layer 2-1 and sizing material layer 13-1 pressure dressing simultaneously adhered on the cotton it to the two sides of cotton, the speed of a motor vehicle of control four-roll calender be 3-10 rice/minute.
For the bottom cotton, then the single face to cotton rolls rubber size on four-roll calender.
What above-described rubber size adopted is that (the weight item percentage of wherein each composition generally is butyronitrile rubber 100 to conventional formulation, zinc oxide 5, stearic acid 1.5, Sulfur 3, promoter 1, carbon black 15, softening agent 8, age resistor 3, blowing agent 10; All these raw materials all are direct outsourcings).
For the cotton of superficial layer, then still continue to use existing steam rubbing method, in cotton single face coating rubber rubber cement and oven dry.
Obviously, in this technology, the rubber layer thickness of intermediate layer cotton and bottom cotton is formed by the roller calendering, so rubber no longer needs to be dissolved into rubber cement, this has just significantly reduced the use amount of solvent (dimethylbenzene or toluene); Do not need simultaneously oven dry, steam consumption also significantly reduces.
2) will be coated with the superficial layer cotton 20 (rubber slurry using faces up) of rubber slurry using, middle level cotton (having 2 layers among the present invention) and the bottom cotton 21 (the rubber size face also up) superimposed directly compound on two roller compounding machines (direction of motion of compound tense cotton is arrow B) afterwards that calendering has rubber size; This operation is identical with existing rubberized fabric compound working procedure.
3) blanket after compound is vulcanized.This operation is also identical with existing operation.
After the sulfuration blanket is carried out grinding, make its requirement up to specification.This operation is also identical with existing operation.
Above-described four-roll calender and two roller compounding machine all are rubber processing conventional equipments.
