Abstract
The invention provides a PET (polyethylene terephthalate) resin bottle cap. The bottle cap comprises the following raw materials in parts by weight: 60-80 parts of PET resin, 0.2-0.4 part of water and magnesium silicate, 0.5-0.8 part of hindered phenol phosphate, 0.3-0.5 part of pigments and 0.2 part of phosphinate or comprises the following raw materials in parts by weight: 60-70 parts of PET resin, 0.2-0.3 part of water and magnesium silicate, 0.5-0.6 part of hindered phenol phosphate, 0.3-0.4 part of pigments and 0.2 part of phosphinate or comprises the following raw materials in parts by weight: 70-80 parts of PET resin, 0.3-0.4 part of water and magnesium silicate, 0.6-0.8 part of hindered phenol phosphate, 0.4-0.5 part of pigments and 0.2 part of phosphinate. The bottle cap is simple in proportioning and has high production efficiency and excellent quality.
Description
Technical field:
The present invention relates to the bottle cap technical field of medicine bottle envelope bottle, particularly a kind of PET resin bottle cap.
Background technology:
PP bottle cap is mainly produced by injection moulding or compression moulding two kinds of modes, because PP shrinking percentage is large, cause must lengthening in process of production the appearance that sizing cooling time of injection moulding machine or plasticator and dwell time just can prevent the defective productss such as the outward appearance of product does not shrink, warpage, interior tooth irregularity.But lengthen the reduction that sizing can cause production efficiency cooling time.Meanwhile, after PP bottle cap places for some time, size can continue contraction and causes size to diminish, the appearance of the phenomenon such as cannot to match with bottleneck size or too tight.Traditional PP bottle cap modifying material reduces the shrinking percentage of PP, but the method for adding filler parent granule exists following shortcoming: the physicals first affecting PP bottle cap, such as reduces surface gloss and mechanical property.Secondly PP bottle cap is much for beverage, food and medicine industry, very strict to hygienic requirements, adds a large amount of filling and there is very large potential safety hazard.Therefore, need to occur that a kind of proportioning is simple, production efficiency is high, a kind of PET resin bottle cap of excellent quality.
Summary of the invention:
The invention provides a kind of proportioning simple, production efficiency is high, a kind of PET resin bottle cap of excellent quality.
In order to realize the object of the invention, the invention discloses a kind of PET resin bottle cap, wherein, comprising the following raw material according to weight parts:
PET resin 60-80 part, water and Magnesium Silicate q-agent 0.2-0.4 part, hindered phenol phosphate ester salt 0.5-0.8 part, pigment 0.3-0.5 part, phosphinates 0.2 part.
Comprise the following raw material according to weight parts:
PET resin 60-70 part, water and Magnesium Silicate q-agent 0.2-0.3 part, hindered phenol phosphate ester salt 0.5-0.6 part, pigment 0.3-0.4 part, phosphinates 0.2 part.
Comprise the following raw material according to weight parts:
PET resin 70-80 part, water and Magnesium Silicate q-agent 0.3-0.4 part, hindered phenol phosphate ester salt 0.6-0.8 part, pigment 0.4-0.5 part, phosphinates 0.2 part.
During preparation, step is as follows: take each raw material by formula, pour in homogenizer and stir, and is then added in twin screw extruder, and 180-240 DEG C melt extrudes granulation and obtain.
The modified salient features of bottle cap of the present invention is as follows:
Reduce the shrinking percentage of bottle cap, prevent the less than normal and interior tooth irregularity of bottle cap size, eliminate the phenomenons such as buckling deformation, for goods provide the dimensional stability of excellence;
Accelerate the crystallization rate of bottle cap, shorten the shaping cycle of goods, improve product molding working (machining) efficiency, increase factory's profit;
Improve the surface gloss of bottle cap;
Eliminate the bubble produced in bottle cap moulding process.
Component is safe and reliable, and bottle cap can be used for beverage, food and medicine industry.
