Description
Technical field
The present invention relates to a kind of synthetic resins pellet and preparation method, specifically, the present invention relates to a kind of fire hose lining synthetic resins pellet and preparation method.
Background technology
Fire hose is a kind of flexible duct of pressure-bearing, and it is made up of outer layer fiber braiding pipe racks and inner liner fit.The lining of commodity fire hose all is rubber materials on the market, and current rubber tube-making process is very ripe, easily reaches the supporting requirement of fire hose lining.But usefulness rubber material manufacturing liner thickness is thick relatively, weight is big, adds rubber raw materials price height, causes production cost high.
Summary of the invention
The present invention is primarily aimed at the deficiency of the supporting rubber mass lining of fire hose, proposes a kind of fire hose lining synthetic resins pellet and preparation method, and it is simple to make lining technology with this pellet, and bearing capacity is strong, flexible foot, and production cost is low.
The present invention is achieved through the following technical solutions technical object.
Fire hose lining synthetic resins pellet, its improvements are that the component that it is measured by mass percentage comprises: polyvinyl chloride resin 30%～32%, light calcium carbonate 36%～40%, o-phthalic acid dibutyl ester 14.5%～16%, dibutyl phthalate (DBP) 12.5%～14%, one package stabilizer 1.6%～2.5% and hexanodioic acid pentaerythritol ester 0.5%～0.7%.The present invention also comprises the fire hose lining preparation method of synthetic resins pellet, and its improvements are to follow these steps to carry out:
Mixing will be put in the high mixer in the lump by the raw material of proportioning metering and mix, and mix at least 15 minutes under 50 ℃ ± 2 ℃ conditions;
Spreading for cooling is divided room temperature to be cooled in open container with compound;
Granulation is injected into compound in the screw extrusion press that has heated, and heating takes the subregion to heat in proper order, and the die head through screw extrusion press when compound is heated to 142 ℃ is extruded into bulk goods.
Polyvinyl chloride resin in the said components is suspension pvc resin, and the polymerization degree is 1300.
As further improvement project, it is the heating of axial subregion from the charging opening of screw extrusion press inner chamber to die head that described subregion heats in proper order, concrete regional Heating temperature: 142 ℃ ± 1 ℃ of 125 ℃ in a district, 125 ℃ in two districts, 130 ℃ in three districts, 130 ℃ in four districts, 135 ℃ in five districts, 140 ℃ in six districts and die head.
The present invention compared with prior art has following positively effect:
1, the component wide material sources are with low cost, and manufacturing process is simple;
2, the lining intensity height of plastic material, withstand voltage, anti-corrosion, difficult be full of cracks;
3, the plastic material flexibility is good, and the fire hose of making is convenient to the collection of reeling.
Embodiment
Further specify the present invention below by embodiment.
The present invention is a kind of fire hose lining synthetic resins pellet, and the component that it is measured by mass percentage comprises: polyvinyl chloride resin 30%～32%, light calcium carbonate 36%～40%, o-phthalic acid dibutyl ester 14.5%～16%, dibutyl phthalate (DBP) 12.5%～14%, one package stabilizer 1.6%～2.5% and hexanodioic acid pentaerythritol ester 0.5%～0.7%.The present invention also comprises the realization fire hose lining preparation method of synthetic resins pellet, and concrete operations follow these steps to carry out: mixing will be put in the high mixer in the lump by the raw material of proportioning metering and mix, and mix at least 15 minutes under 50 ℃ ± 2 ℃ conditions; Spreading for cooling is divided room temperature to be cooled in open container with compound; Granulation is injected into compound in the screw rod machine that has heated, heating takes the subregion to heat in proper order, namely axially divide 7 zone heating from the charging opening of screw extrusion press inner chamber to die head, 142 ℃ of 125 ℃ in a district, 125 ℃ in two districts, 130 ℃ in three districts, 130 ℃ in four districts, 135 ℃ in five districts, 140 ℃ in six districts and die heads.Die head through screw extrusion press when compound is heated to 142 ℃ ± 1 ℃ is extruded into bulk goods.
Embodiment 1～3
Embodiment below by three different proportionings further specifies the present invention, and concrete proportioning sees the following form one, and the salient features data see Table two.
Table one, proportioning
Table two, synthetic resins pellet salient features data
The synthetic resins pellet salient features data that state clearly from table two as can be known, the pellet the key technical indexes of above-mentioned three embodiment preparation all is better than the performance of general soft PVC, considerably beyond rubber.Component of the present invention is reasonable, and proportioning is appropriate, and the preparation method is easy, and for the manufacture of fire hose lining tensile strength height, flexible good, corrosion resistance is strong, and production cost is low.The present invention is suitable for making the fire hose of various occasions uses and the lining of agricultural Flexible water pipe.
