Background technology
Master batch, is made up of the chemical assistant, vector resin and dispersant of excess.Master batch is that the chemical assistant of super quantity is equal
It is even to be attached to aggregation obtained from resin.Conventional master batch is divided into cooling masterbatch, blast master batch, moisture absorption foam eliminating mother particle, resistance
Fire master batch and foaming master batch.
Chemical blowing process is the effective ways for producing expandability cellular plastic, exploitation injection and extrudate.But in foaming
Often occur the problems such as string steeps and steeped in forming process, it is most of because foaming agent disperses bad cause.The method of solution
It is the dispersion for foaming agent being made into high concentration, i.e., foaming agent, polymer is kneaded, granulates producing foamed agent master batch.Hair
Infusion master batch not only solves the dispersion problem of foaming agent, the problems such as also solving dust from flying, error in dipping.And pass through
The setting of formula and technological parameter, successfully solve foaming agent foam temperature it is too low and the problem of be difficult early grain.
It is expected to effectively reduce the density of material on the premise of material impact toughness is improved using microporous foam technology.With biography
The cost increase and intensity, rigidity that the elastic body toughening of system is caused are significantly reduced and compared, with obvious advantage.Manufacture micropore material
The method of material is a lot, and wherein chemical blowing process is the effective ways for producing expandability cellular plastic, exploitation injection and extrudate.

Further, present invention additionally comprises the component of following parts by weight：100 parts of LDPE, 16-18 parts of PE waxes, foaming agent
30-32 parts of BIF, 0.15-0.20 parts of antioxidant BHT, 1500 1.5-2.0 parts of mesh calcium carbonate.
Further, the present invention also protects the preparation method of above-mentioned chemical blowing master batch, comprises the following steps：(1) will
Each component is mixed by proportioning；(2) well mixed material is sent into double screw extruder and granulated.
Further, the present invention also protects the preparation method of above-mentioned chemical blowing master batch, the double screw extruder
Rotating speed 350r/min, feeding rotating speed 7r/min；Double screw extruder is divided into ten humidity provinces, the double screw extruder temperature control
System is as follows：One area's temperature：70℃；Two area's temperature：80℃；Three area's temperature：85℃；Four area's temperature：90℃；Five area's temperature：90℃；
Six area's temperature：95℃；Seven area's temperature：95℃；Eight area's temperature：95℃；Nine area's temperature：95℃；Ten area's temperature：95℃；Head temperature
Degree：105℃.
The present invention adds PE waxes collaboration reinforcement system and melted by the use of the PE powder that fusing point is relatively low, melting means is higher as carrier
Refer to, it is ensured that the mobility of system under conditions of low temperature, obtained on the basis of not foaming in advance by way of extruding pelletization
This product.The present invention selects food grade materials, using PE as carrier, PE waxes as enhancing melting means medium, and add nucleator guarantor
Demonstrate,prove uniform in foaming, good product effect.
Brief description of the drawings
Relation between Fig. 1 impact strengths and nucleator；
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with specific embodiment to this
Invention is further elaborated.
Reagent：LDPE Plant of Tianjin Petrochemical Company 2650F (powder), PE wax BASF A waxes, foaming agent Ke Laien BIF, antioxidant Germany
Bright Sheng BHT, 1500 mesh talcum powder.
Step：
Each above-mentioned composition is tested according to following ratio
100 parts of LDPE Plant of Tianjin Petrochemical Company 2650F (powder), 16 parts of PE wax BASF A waxes, 32 parts of foaming agent Ke Laien BIF,
Bright 0.15 part of the Shengs BHT of antioxidant Germany, 1500 mesh talcum powder be it is a series of, respectively 0,0.5,1.0,1.5,2.0,2.5,3.0
Part.
Above-mentioned formula is added into double screw extruder successively according to aforementioned proportion, wherein turn of double screw extruder
Fast 350r/min, feeding rotating speed 7r/min.
Double screw extruder is divided into ten humidity provinces by operating personnel, and the double screw extruder temperature control is as follows：One
Area's temperature：70℃；Two area's temperature：80℃；Three area's temperature：85℃；Four area's temperature：90℃；Five area's temperature：90℃；Six area's temperature：
