Abstract
The invention provides a medicine bottle cap. The medicine bottle cap comprises the following raw materials in parts by weight: 60-80 parts of polyethylene particles, 0.2-0.4 part of phthalate, 0.5-0.8 part of lead salt and 0.3-0.5 part of coupling agent or comprises the following raw materials in parts by weight: 60-70 parts of polyethylene particles, 0.2-0.3 part of phthalate, 0.5-0.6 part of lead salt and 0.3-0.4 part of coupling agent or comprises the following raw materials in parts by weight: 70-80 parts of polyethylene particles, 0.3-0.4 part of phthalate, 0.6-0.8 part of lead salt and 0.4-0.5 part of coupling agent. The medicine 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 cap of medicine bottle.
Background technology:
Polyethylene bottle cap is mainly produced by injection moulding or compression moulding two kinds of modes, because polyethylene shrink rate 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 polyethylene 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 polyethylene bottle cap modifying material reduces poly shrinking percentage by adding filler parent granule, but there is following shortcoming in the method for adding filler parent granule: the physicals first affecting polyethylene 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 cap of medicine bottle of excellent quality.
Summary of the invention:
The invention provides a kind of proportioning simple, production efficiency is high, a kind of cap of medicine bottle of excellent quality.
In order to realize the object of the invention, the invention discloses a kind of cap of medicine bottle, wherein, comprising the following raw material according to weight parts:
Polyethylene particle 60-80 part, phthalic ester
0.2-0.4 part, lead salt 0.5-0.8 part, coupling agent 0.3-0.5 part.
Comprise the following raw material according to weight parts:
Polyethylene particle 60-70 part, phthalic ester
0.2-0.3 part, lead salt 0.5-0.6 part, coupling agent 0.3-0.4 part.
Comprise the following raw material according to weight parts:
Polyethylene particle 70-80 part, phthalic ester
0.3-0.4 part, lead salt 0.6-0.8 part, coupling agent 0.4-0.5 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.
