Abstract
The invention aims to provide a production process of PVC rubber of soundproof cotton. The production process comprises the following steps: screening a raw material and an additive, highly stirring and mixing the raw material with the additive, conveying the mixture of the raw material and the additive to a plasticizing and mixing machine to thoroughly and fully plasticize and mix the mixture, conveying the mixture to an extrusion molding machine, extruding the mixture to a calender for calendering molding, and finally performing cooling, cutting and rolling. All the steps interact to ensure a uniform PVC rubber product and the quality of the PVC rubber. The production process is suitable for production.
Description
Technical field
The present invention relates to the PVC rubber field of Sound-proof material, particularly relate to the production technology of the PVC rubber of a kind of Sound-proof material.
Background technology
My company mainly produces PVC rubber, and PVC rubber is for Sound-proof material, and PVC rubber glues one layer of cotton felt after being coated with gluing just becomes Sound-proof material, is cut into required shape afterwards again, afterwards the part that cotton felt side is coated on required sound insulation inwardly is carried out sound insulation.PVC rubber is the key component of Sound-proof material, and PVC rubber needs Sound-proof material is protected, and therefore its performance need is very excellent.Perfect not for the production technology of PVC rubber at present, therefore solve the problems referred to above and just seem very necessary.
Summary of the invention
For solving the problems referred to above, the present invention provides the production technology of the PVC rubber of a kind of Sound-proof material, first raw material and additive are sieved mixing, add water after mixing stirring, post-heating be delivered to molding in extrusion shaping machine again, finally cooling cutting rolling, there is interaction in each step, guarantee that PVC rubber finished product is uniform, it is ensured that the quality of PVC rubber, solve produced problem in background technology.
It is an object of the invention to provide the production technology of the PVC rubber of a kind of Sound-proof material, include following steps:
Step one: sieved by PVC raw material, removes bulky grain thing, weighs the PVC raw material of corresponding number；
Step 2: sieved by additive, removes bulky grain thing, weighs the additive of corresponding number；
Step 3: load weighted PVC raw material and additive are put into the stirring mixing of blender high speed；
Step 4: the material of step 3 is delivered to and pounds turbine material is thoroughly fully plastified mixing；
Step 5: step 4 material is delivered to extrusion shaping machine and is expressed into calender calendering for required rubber；
Step 6: the rubber after molding is delivered to coolconveyer and cools down；
Step 7: the rubber after cooling is cut into required specification；
Step 8: the rubber cut carries out rolling packaging warehouse-in.
Further improvement is that: described step 3 mixing time is 0.5-1h.
Further improvement is that: the temperature of described step 4 is 180-220 DEG C.
Further improvement is that: the temperature of described extrusion shaping machine is 160-220 DEG C.
Beneficial effects of the present invention: raw material and additive are first sieved mixing by the present invention, add water after mixing stirring, post-heating be delivered to molding in extrusion shaping machine again, finally cooling cutting rolling, there is interaction in each step, guarantee that PVC rubber finished product is uniform, it is ensured that the quality of PVC rubber, 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 the production technology of the PVC rubber of a kind of Sound-proof material, includes following steps:
Step one: sieved by PVC raw material, removes bulky grain thing, weighs the PVC raw material of corresponding number；
Step 2: sieved by additive, removes bulky grain thing, weighs the additive of corresponding number；
Step 3: load weighted PVC raw material and additive are put into the stirring mixing of blender high speed；
Step 4: the material of step 3 is delivered to and pounds turbine material is thoroughly fully plastified mixing；
Step 5: step 4 material is delivered to extrusion shaping machine and is expressed into calender calendering for required rubber；
Step 6: the rubber after molding is delivered to coolconveyer and cools down；
Step 7: the rubber after cooling is cut into required specification；
Step 8: the rubber cut carries out rolling packaging warehouse-in.
Described step 3 mixing time is 0.5-1h.The temperature of described step 4 is 180-220 DEG C.The temperature of described extrusion shaping machine is 160-220 DEG C.
First raw material and additive being sieved mixing, add water after mixing stirring, post-heating be delivered to molding in extrusion shaping machine again, finally cooling cutting rolling, there is interaction in each step, it is ensured that PVC rubber finished product is uniform, ensure the quality of PVC rubber, it is adaptable in production.
