Abstract
The invention discloses a process for producing colorful rubber for table tennis bats, which is low in production cost and high in pattern adhesive force. The process comprises the following steps of: mixing natural rubber, a vulcanizing agent and an accelerating agent to form raw rubber; milling the mixed raw rubber into rubber with the required thickness on a sheet outlet machine, and controlling the sheet outlet temperature to 55-65 DEG C; cutting the milled raw rubber sheet into the rubber in an early form, wherein the raw rubber sheet cannot be stretched during cutting to ensure that the raw rubber sheet is prevented from thinning and deforming; adhering a film printed with a pattern on the rubber sheet, wherein the position of the pattern is required to be symmetrical to that of the rubber sheet in an all-around mode; putting the rubber sheet adhered with the film in a flat-plate mold of the rubber, and vulcanizing the rubber sheet in a vulcanizing machine at a high vulcanizing temperature of between 175 and 185 DEG C for 4 to 6 minutes; immediately uncovering the high-temperature film on the surface of the rubber after demolding; and cooling the demolded rubber at normal temperature for 22 to 30 minutes so as to stack up the rubber when the temperature is reduced to be less than 70 DEG C.
Description
Technical field
The present invention relates to the colored rubber production technology of a kind of table tennis bat.
Background technology
On positive and negative two faces of table tennis bat, all be provided with rubber, the rubber that existing explained hereafter is come out, color is more single; Have only common black, redness etc., look more attractive in appearance, satisfy children's instructions for use in order to make table tennis bat; Generally need on rubber, print different patterns, pattern generally be through transfer printing or silk-screen to rubber, pattern adhesive force is bad; Printing process has peculiar smell, and is toxic, influences the healthy of operator and use children.
Summary of the invention
Technical problem to be solved by this invention is: provide the table tennis bat that a kind of production cost is lower, pattern adhesive force is good colored rubber production technology.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopts is: the colored rubber production technology of table tennis bat; Comprise the steps: with natural rubber with vulcanizing agent, promoter mixing are developed into rubber---the rubber that mixes is ground the thickness that is pressed into needs on film-discharging machine; 55 ℃-65 ℃ of control slice temperature---will grind the blank that the raw stock that presses is cut into rubber as required; Can not draw high raw stock during cutting; Preventing raw stock attenuation, distortion---the film that will be printed on pattern is attached on the film; Pattern position will symmetry---the film that will post film be placed on the rubber flat plate mold up and down with the rubber position, and it is high temperature vulcanized to insert vulcanizer, and the rubber of curing temperature behind 175 ℃-185 ℃, time 4-6 minute---throwing off the high temperature membrane on rubber surface after the demoulding immediately---demoulding cools off at normal temperatures and the rubber temperature reduced stack below 70 ℃.
Advantage of the present invention is: the colored rubber production technology of above-mentioned table tennis bat, and pattern just is printed directly on the rubber in the rubber production process, and technology is simple; Production cost is lower; Pattern adhesive force is good, and the printing process free from extraneous odour has guaranteed the operator and used that children's is healthy.
The specific embodiment
Describe particular content of the present invention in detail below in conjunction with accompanying drawing and specific embodiment.
