Abstract
An embodiment of the invention discloses a preparing method of an energy-saving flame-retardant raw material. The preparing method includes preparing raw materials comprising ABS and PVC, a filler that is calcium carbonate and a modifying material, adding the raw materials comprising the ABS and the PVC, the filler that is the calcium carbonate and the modifying material into a high-speed heating mixer, mixing to change the structure of the raw material ABS to allow the plasticizing temperature of the ABS to be same as that of the PVC, adding a plasticizer, mixing continuously, twisting and cutting under the action of a conical twin-screw extruder, mixing, granulating, and performing hot cutting. The energy-saving flame-retardant raw material is further provided, and comprises the ABS, the PVC, the filler that is the calcium carbonate and the modifying material. The objective of the invention is to provide the energy-saving flame-retardant raw material simple in production process and good in flame retardant effects, and the preparing method thereof.
Description
Technical field
The present invention relates to energy-conserving fire retardant raw material field, particularly relate to a kind of energy-conserving fire retardant raw material and preparation method thereof.
Background technology
Existing fire retardant material ABS, PVC can not be well compatible, and energy-conserving fire retardant is very poor.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, provides the preparation method of the energy-conserving fire retardant raw material that a kind of production technique is simple, flame retardant effect is better.
The preparation method of described energy-conserving fire retardant raw material, comprises the steps:
(1) raw material A BS, PVC, packing material calcium carbonate and material modified is prepared;
(2) are mixed above-mentioned raw materials ABS, PVC, packing material calcium carbonate and material modified adding in the mixed machine of heat at a high speed, the structure of feed change ABS molecule, makes it have identical plasticization temperature with described PVC, then adds softening agent, continues mixing;
(3) twist and cut under the effect of cone twin screw extruder, mixing granulation, earnestly.
Described step (2) ABS, PVC, material modified, calcium carbonate mixes after to 80 degree in the mixed machine of high speed heat, adds softening agent, continues to mix to 110 degree, mix to 40 degree cold.
In described step (3), extruder temperature is respectively, 190 degree, 195 degree, 180 degree, 178 degree, 175 degree, 170 degree.
Energy-conserving fire retardant raw material prepared by the preparation method that the embodiment of the present invention additionally provides a kind of energy-conserving fire retardant raw material, comprises following composition: ABS, PVC, packing material calcium carbonate and material modified.
Implement the embodiment of the present invention, there is following beneficial effect:
First embodiment of the present invention energy-conserving fire retardant raw material make use of the self flame retardance of PVC and fills the obstruct flame retardant resistance of stone flour, stone flour is filled with PVC after ABS is decomposed completely, binder after abundant dispersion fusion, its flame retardant resistance is that quite stable is reliable, its secondary ABS of making melts with PVC phase, modification will be carried out to two kinds of materials, and make it plastify at that same temperature, and allow bi-material have seam value molten mutually mutually when different ratios by the different add-on of modification.Make it reach to melt completely mutually.
ABS is polystyrene plastic, and the three components based on acrylonitrile (A), divinyl (B) and vinylbenzene (S) formed.Plasticizing just must change the structure of its molecule at low temperatures, plasticization temperature identical with PVC after its molecule is changed, the ratio volume of its bi-material is different, and material modified dosage is also different, and its dosage ratio is directly proportional with bi-material proportion in total amount.In thermally-stabilised, bi-material plastifies at the same temperature, and the impact of simultaneously not heated in the course of processing, obtains good control on thermally-stabilised in certain temperature interval.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below the present invention is described in further detail.
The preparation method of a kind of energy-conserving fire retardant raw material of the embodiment of the present invention, comprises the steps:
