Abstract
The invention discloses a PVC (polyvinyl chloride) rubber compound mixing method which comprises the following steps: (1) compounding: according to the formula, weighing raw materials including oil, a flame retardant and surplus materials; (2) adding all the raw materials except the oil to a mixing barrel; (3) stirring evenly the materials in the mixing barrel; (4) adding the oil into the mixing barrel; and (5) continuing stirring the materials in the mixing barrel evenly. The PVC compound rubber compound mixing method, compared with the prior, changes the oil adding time, the oil is added after the raw materials except the oil are evenly stirred, and in the beginning, due to the occurrence of oil wrapping on the flame retardant, the uniformity of mixing is improved.
Description
Technical field
The present invention relates to the production technology of PVC CABLE MATERIALS, relate in particular to the blending means of PVC sizing material.
Background technology
The production of PVC CABLE MATERIALS comprise the proportioning raw materials, PVC sizing material of PVC sizing material mix, by mixed PVC sizing material successively after the equipment such as feeding machine, forcing machine, air-cooled die-surface hot cutting head, cyclonic separator and air-cooled lengthening vibratory screening apparatus, with output PVC CABLE MATERIALS.
Raw material packet oil scraper, fire retardant and other batchings of PVC sizing material, in the time that PVC sizing material mixes, first all batchings of PVC sizing material are joined in agitation vat simultaneously, because oily existence meeting wraps fire retardant, easily make fire retardant disperse inhomogeneous, make that in final PVC CABLE MATERIALS particle, some has fire retardant, some does not have fire retardant.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of blending means of PVC sizing material, improve the homogeneity of mixing of materials.
Technical scheme: for achieving the above object, the technical solution used in the present invention is:
The blending means of PVC sizing material, comprises the steps:
(1) batching: take out raw material by formula, described raw material packet oil scraper, fire retardant and clout;
(2) all raw materials beyond oil are joined in agitation vat;
(3) material in agitation vat is stirred to evenly;
(4) oil is joined in agitation vat;
(5) continue the material in agitation vat to be stirred to evenly.
Preferably, in described step (3), the material in agitation vat is stirred to uniform churning time more than 5min.
Beneficial effect: the blending means of PVC sizing material provided by the invention, the prior art of comparing, has changed the oily joining day, and the raw material stirring beyond oil just adds oil after evenly, the parcel situation due to oil, fire retardant being produced when initial occurs, and improves the homogeneity stirring.
Embodiment
Below in conjunction with example, the present invention is further described.
The blending means of PVC sizing material, comprises the steps:
(1) batching: take out raw material by formula, described raw material packet oil scraper, fire retardant and clout;
(2) all raw materials beyond oil are joined in agitation vat;
(3) material in agitation vat is stirred to evenly, churning time is greater than 5min;
(4) oil is joined in agitation vat;
(5) continue the material in agitation vat to be stirred to evenly.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (2)
- The blending means of 1.PVC sizing material, is characterized in that: comprise the steps:(1) batching: take out raw material by formula, described raw material packet oil scraper, fire retardant and clout;(2) all raw materials beyond oil are joined in agitation vat;(3) material in agitation vat is stirred to evenly;(4) oil is joined in agitation vat;(5) continue the material in agitation vat to be stirred to evenly.
- 2. the blending means of PVC sizing material according to claim 1, is characterized in that: in described step (3), the material in agitation vat is stirred to uniform churning time more than 5min.
