Abstract
The invention discloses a production technique of high-speed rail carriage bottom plate. The technique comprises the following steps: (1) raw material mixing: mixing PVC (polyvinyl chloride), additives for plastics and a filler according to the ratio of 5:2:3; (2) stirring: when the stirrer is heated to 180 DEG C, adding the mixed raw materials in the step (1) into the stirrer, and stirring; (3) extrusion molding: putting the mixed raw materials stirred in the step (2) into an extruder, and extruding to obtain the 20mm-thick base plate; (4) cooling: cooling the base plate in the step (3) by a cooling tank to form; and (5) cutting: cutting the formed base plate in the step (4) in a cutting machine according to the specified size. The high-speed rail carriage bottom plate has the advantages of high corrosion resistance, favorable water resistance, favorable fire resistance and the like.
Description
Technical field
The present invention relates to a kind of production technology of high-iron carriage base plate, floor processing technique field is applied to.
Background technology
With the development of society, the track traffic of China also quickly grows, and high ferro turns into main long range social now
Manned transport vehicle, therefore the fire prevention of base plate in high ferro, waterproof, anticorrosive property are very important, currently on the market
The combination property of track traffic base plate is poor, it is necessary to the frequency of maintenance is high.
The content of the invention
It is above-mentioned to solve the problems, such as, the invention discloses a kind of strong, the formaldehydeless high-iron carriage base plate of corrosion resistance, including
Following steps：
（1）Raw material mixes：By PVC, plastic additive, inserts according to 5:2:3 ratio mixing；
（2）Stirring：Stirred during the mixed material in step one is added into mixer when mixer is heated to 180 DEG C；
（3）Extrusion molding：Mixed material after being stirred in step 2 is put into extruding machine, extrusion thickness is the substrate of 20mm；
（4）Cooling：Substrate in step 3 is passed through into cooler bin cooling and shaping；
（5）Cutting：By the substrate after cooling and shaping in step 4, size is cut in cutting machine according to the rules.
Further：Described inserts is the leftover pieces after timber and PVC substrate cuts.
Further：Described plastic additive is lubricant, heat stabilizer, impact modifier and processing aid, its quality
Than for：1:1:1:2.
Beneficial effects of the present invention are：Increase PVC floor by adding lubricant, heat stabilizer, impact modifier
Corrosion-resistant, fire-proof and water-proof performance, and by appropriate proportioning, strengthen its combination property.
Specific embodiment
The invention discloses a kind of production technology of high-iron carriage base plate, comprise the following steps：
（1）Raw material mixes：By PVC, plastic additive, inserts according to 5:2:3 ratio mixing；
（2）Stirring：Stirred during the mixed material in step one is added into mixer when mixer is heated to 180 DEG C；
（3）Extrusion molding：Mixed material after being stirred in step 2 is put into extruding machine, extrusion thickness is the substrate of 20mm；
（4）Cooling：Substrate in step 3 is passed through into cooler bin cooling and shaping；
（5）Cutting：By the substrate after cooling and shaping in step 4, size is cut in cutting machine according to the rules.
Further：Described inserts is the leftover pieces after timber and PVC substrate cuts.
Further：Described plastic additive is lubricant, heat stabilizer, impact modifier and processing aid, its quality
Than for：1:1:1:2.
Finally it should be noted that：Above example is only used to illustrate the present invention and not limit technology described in the invention
Scheme；Therefore, although this specification with reference to each above-mentioned embodiment to present invention has been detailed description, this
Field it is to be appreciated by one skilled in the art that still can be modified to the present invention or equivalent；And all do not depart from this
The technical scheme of the spirit and scope of invention and its improvement, it all should cover in scope of the presently claimed invention.
