Face out-of-flatness, upper and lower Shamian Island is uneven, and feel is bad, and product appearance is simply common, in order to promote PE bottles of appearance class and hand
Sense, it is necessary to pass through secondary spray process.Secondary spraying is to spray a kind of compound body (paint) of industrial chemicals, shape in PE bottle surface
At the paint film with certain feel and visual effect.But spraying process is complicated, and also has an impact to bottle size function, no
Only cost is big, and the lacquer painting of surface spraying is also easy removing in use and falls, while more entire technique of spraying process
Production cycle significantly extends extension, and the environmental-protecting performance of compound body (paint) itself is also bad.
Summary of the invention
The present invention aiming at the shortcomings in the prior art, provides a kind of PE bottle surface blow molding frosted method, and this method passes through
It directly is blow molded out frosted finish effect on bottle body surface after two kinds of HDPE mixing, due to being blow molding, bottle body size function will not be made
It is shaped to, while compared to then save the cost, shortening production cycle and the environmental protection of secondary spraying process.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals: PE bottle surface is blow molded frosted
Method, including the following steps: step (A): HDPE5502 and HDPE571 is carried out to be mixed to form mixture, the mixing
The mass ratio of HDPE5502 and HDPE571 is 1 ~ 10:3 in material;Step (B): mixture will be put into bottle blowing machine platform, then
Heating preheating is carried out to bottle blowing machine platform, wherein the barrel preheating temperature in bottle blowing machine platform is 210 DEG C ~ 260 DEG C, preheating time 60
Minute to 90 minutes, the runner preheating temperature in bottle blowing machine platform is 200 DEG C ~ 230 DEG C, and preheating time is 60 minutes to 90 minutes,

Afterwards, the operating current of bottle blowing machine platform with the frequency of 5HZ work to the mixture carry out feeding formed material base, feeding by
Gradually smooth rear operating current is worked with the frequency of 2HZ increases mixture to required material base length;Step (D): expecting
Gradually cooling is carried out to material base until apparent frosted finish effect occurs in material base surface during base blow molding.In temperature-fall period
The middle temperature difference for keeping material base surface and bottle blowing machine platform that there are 5 DEG C ~ 10 DEG C.
In above-mentioned technical proposal, it is preferred that in step (A), the quality of HDPE5502 and HDPE571 in the mixture
Than for 1:1.
In above-mentioned technical proposal, it is preferred that in step (B), barrel preheating temperature in bottle blowing machine platform be 210 DEG C or
230 DEG C or 240 DEG C or 260 DEG C, preheating time is 75 minutes, and the runner preheating temperature in bottle blowing machine platform is 220 DEG C, preheating time
It is 75 minutes, mouth mold preheating temperature is 200 DEG C or 220 DEG C in bottle blowing machine platform, and preheating time is 75 minutes.
In above-mentioned technical proposal, it is preferred that increasing, stopping in step (c), when if operating current is than operating normally
Bottle blowing machine platform stops feeding, and preheats again to bottle blowing machine platform.
In above-mentioned technical proposal, it is preferred that in step (D), material base surface and bottle blowing machine platform are kept in temperature-fall period
With 7 DEG C ~ 8 DEG C of the temperature difference.
The present invention is a kind of blow moulding process, and compared with the prior art, this method passes through HDPE5502 and HDPE571 material
Mixing and special process can directly be blow molded out frosting.The principle of this method is after HDPE5502 and HDPE571 is mixed
The small group of a large amount of different densities is formed in certain temperature, then these small groups solidify under the adjusting of temperature
Form the surface with small husky sense.Frosted finish effect feel quality controlled whether finely mainly by temperature, frosted finish effect vision
Density mainly see the proportion of HDPE5502 and HDPE571.
Compared with prior art, this method is directly blow molded out frosted finish effect on bottle body surface after mixing by two kinds of HDPE,
Due to being blow molding, bottle body size function will not be caused to be formed, while then save the cost, shortening are given birth to compared to secondary spraying process
Produce period and environmental protection.
HDPE is the English abbreviation of high density polyethylene (HDPE), and HDPE5502 and HDPE571 are respectively the two of high density polyethylene (HDPE)
Kind model.
