Abstract
The invention aims at providing a calendaring process for manufacturing a PVC (polyvinyl chloride) rubber cover. The process comprises the following steps: mixing raw materials at a high speed; smelting and mixing the raw materials; calendaring, wherein the raw materials are subjected to metal detection before calendaring, and smoke suppression flame retardants coat the surface of rubber sheets after the calendaring; drying; then cooling and conveying; finally coiling. With the adoption of the process, the produced PVC rubber sheets are outstanding in sound insulating, flame retarding and smoke suppressing performances; the process is applied to production.
Description
Technical field
The present invention relates to the production field of PVC rubber, particularly relate to a kind of technique rolled and make PVC rubber.
Background technology
My company mainly produces PVC rubber.PVC rubber is used for Sound-proof material, and PVC rubber is coated with viscous one layer of cotton felt after gluing and becomes as Sound-proof material, is cut into required shape the most again, afterwards the part that cotton felt side is coated on required sound insulation inwardly is carried out sound insulation.PVC rubber is the chief component of Sound-proof material.Therefore its sound isolating and flame-retardant smoke suppressing is particularly significant, and therefore for PVC rubber, the product how producing excellent properties is particularly significant.Therefore solve the problems referred to above and just seem the most necessary.
Summary of the invention
For solving the problems referred to above, the present invention provides a kind of technique rolled and make PVC rubber, first raw material is carried out mixed at high speed, carries out banburying, mixing afterwards, roll afterwards, before calendering, it is detected metal, after calendering to film face coat smoke inhibition fire retardant, post-drying, finally carry out cold go carry rolling, the PVC film sound isolating and flame-retardant smoke suppressing that this technique is produced is the most excellent, solves produced problem in background technology.
It is an object of the invention to provide a kind of technique rolled and make PVC rubber, include following steps:
Step one: the various raw materials first weighing corresponding formula join stirring 30-50min in homogenizer, sieve after stirring removal bulky grain thing；
Step 2: the material of stirring mixing is joined and carries out banburying 2-5min in banbury；
Step 3: the material after banburying is joined in mill and carry out mill 5-10min；
Step 4: the plasticizing material addition after mill joined in calender and roll, first carries out metal detection to plasticizing material before calendering；
Step 5: calender is rolled the rubber and carries out deflecting from stretching；
Step 6: the material deflecting from stretching is carried out upper and lower surface coating smoke inhibition fire retardant, afterwards it is carried out infrared drying；
Step 7: the material of step 6 is delivered to cold go conveying roller carry out cooling conveying；
Step 8: carry out the material of cooling cutting off rolling.
Further improvement is that: the plasticizing material that described step 4 mill is crossed is transported in calender calendering by screw extruder.
Further improvement is that: described step 7 cooling conveying tail end just along with carrying out trimming to the both sides of film, and trimming waste recovery utilizes.
Further improvement is that: the material of described step 8 rolling cures 8-12h in being delivered to cure room.
Beneficial effects of the present invention: the present invention first carries out mixed at high speed to raw material, carry out banburying, mixing afterwards, roll afterwards, before calendering, it is detected metal, after calendering to film face coat smoke inhibition fire retardant, post-drying, finally carry out cold go carry rolling, the PVC film sound isolating and flame-retardant smoke suppressing that this technique is produced is the most excellent, it is adaptable in production.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment is only used for explaining the present invention, is not intended that limiting the scope of the present invention.
The present embodiment provides a kind of technique rolled and make PVC rubber, includes following steps:
Step one: the various raw materials first weighing corresponding formula join stirring 30-50min in homogenizer, sieve after stirring removal bulky grain thing；
Step 2: the material of stirring mixing is joined and carries out banburying 2-5min in banbury；
Step 3: the material after banburying is joined in mill and carry out mill 5-10min；
Step 4: the plasticizing material addition after mill joined in calender and roll, first carries out metal detection to plasticizing material before calendering；
Step 5: calender is rolled the rubber and carries out deflecting from stretching；
Step 6: the material deflecting from stretching is carried out upper and lower surface coating smoke inhibition fire retardant, afterwards it is carried out infrared drying；
Step 7: the material of step 6 is delivered to cold go conveying roller carry out cooling conveying；
Step 8: carry out the material of cooling cutting off rolling.
The plasticizing material that described step 4 mill is crossed is transported in calender calendering by screw extruder.Described step 7 cooling conveying tail end just along with carrying out trimming to the both sides of film, and trimming waste recovery utilizes.The material of described step 8 rolling cures 8-12h in being delivered to cure room.
First raw material is carried out mixed at high speed, carry out banburying, mixing afterwards, roll afterwards, before calendering, it is detected metal, after calendering to film face coat smoke inhibition fire retardant, post-drying, finally carry out cold go carry rolling, the PVC film sound isolating and flame-retardant smoke suppressing that this technique is produced is the most excellent, it is adaptable in production.
