Abstract
The invention discloses a half-water-soluble plastic laundry bag. The half-water-soluble plastic laundry bag comprises a laundry bag body, an opening is formed in the upper end of the laundry bag body which is composed of an EVA water soluble plastic film and an EVA water soluble thread, the middle of the laundry bag body is connected with hot-melt glue through the EVA water soluble plastic film, the EVA water soluble thread is arranged on the outer side of the laundry bag body and used for binding the laundry bag, the EVA water soluble plastic film and the EVA water soluble thread will melt when encountering water in the washing process, and therefore clothes fall off. The half-water-soluble plastic laundry bag has the appearance of a common plastic film and the characteristic that the common plastic film is completely dissolved in room-temperature water, a certain proportion of calcium carbonate superfine powder is added in the technology, mixed and stirred evenly, the surface of the produced film is uneven, and negative pressure between films is reduced to separate the films; in this way, it is guaranteed that the film is easy to open, the hardness of the film can be increased, and the production cost of the film can be lowered.
Description
Technical field
The present invention relates to injection mo(u)lding manufacturing technology field, particularly relate to a kind of half water-soluble plastics laundry bag and manufacturing technique thereof.
Background technology
Along with the continuous lifting that product function requires, the structural design of plastic product becomes increasingly complex, and quality requirement also improves constantly.Under the multiple demand such as structural strength, precision, production cycle, energy-conserving and environment-protective taking into account product, plastic product forming technique is constantly weeded out the old and bring forth the new.Blow molding, also known as quick-cooling, heating shaping (RHCM) and steam blow molding etc., is a kind of blow molding technique emerging in recent years.Its principle mainly utilizes and three-dimensional makes the temperature in mould raise rapidly and reduce without converging line mould and temperature control device, thus make working of plastics apparent mass be improved significantly.This technology can the shape on copy mold surface well, and make the defects such as product surface weldless trace, current mark, surface gloss is high, and intensity and case hardness are improved, and without the need to follow-up spraying coating process.
Plastics and iron and steel, timber, cement are listed as four large pillars of Material Field, and the development of the Plastics Industry of the world today is more and more rapider, and its purposes has penetrated into the various aspects of people's daily life.But plastics also bring the one side-pollution be extremely harmful to the mankind bringing easily while.Along with the raising of people's living standard; people are to environmental protection also pay attention to day by day; the plastic products series of problems that especially plastic bag brings to environment after using has caused the concern of the whole society; and it is also perfect not to the processing method of plastic refuse at present; mainly contain the modes such as landfill, burning and recovery; due to the recovery of plastics and regeneration rate low, its effect is not ideal.
In the face of a series of difficult problems that plastics bring, people have found answer by degradative plastics.Degradative plastics is a class novel high polymer material with degradation function, it is with in front or use procedure, have quite with similar common plastics or close application performance and sanitation performance, and after completing its using function, under natural environmental condition, the fragment or broken end that are easy to be dissolved by environment can be degraded into quickly, and passing is in time degraded into CO further
2and water, final back to nature.
Summary of the invention
The object of the invention is to solve the shortcoming existed in prior art, and the water-soluble plastics laundry bag of one half proposed.
To achieve these goals, present invention employs following technical scheme:
A kind of half water-soluble plastics laundry bag, comprise laundry bag body, the upper end of described laundry bag body is provided with opening, described laundry bag body is made up of the water-soluble plastic film of EVA and the water-soluble line of EVA, be be connected with thermosol glue by the water-soluble plastic film of EVA in the middle of described laundry bag body, be provided with the water-soluble line of EVA outside described laundry bag body, the water-soluble line of EVA is for bundling laundry bag, the water-soluble plastic film of described EVA and the water-soluble line of EVA are met water in laundry processes and can be dissolved, and clothing is deviate from.
Preferably, the Thickness Ratio of described HDPE plastic layer, LDPE plastic layer and PP plastic layer is 3:2:1.
A manufacturing technique for half water-soluble plastics laundry bag, comprises the steps:
S1, by HDPE, LDPE, PP plastic raw materials wherein one put inflation film manufacturing machine into, shaping, rolling;
S2, in type plastic bag is put into equipment, by the one side of plastic bag separately, then coats thermosol glue, the one side bonding separated by plastic bag with EVA water-soluble plastic film, is sidelong to the water-soluble line of EVA at plastic bag one afterwards, after rolling again;
S3, the plastic bag wound put to machinery and cut finished product.
A kind of half water-soluble plastics laundry bag provided by the invention, compared with prior art, the present invention is a kind of half water-soluble plastics laundry bag, half water-soluble plastics laundry bag of the present invention has the outward appearance of common plastic film and it is dissolved in the characteristic of room temperature water completely, simultaneously, due to its biological degradability and the multi-purpose feature of environmental protection, its use not only can increase rapidly, and indispensable; In technique of the present invention, add a certain proportion of calcium carbonate superfine powder powder, mixing and stirring, the surface relief of the film produced is uneven, reducing intermembranous negative pressure makes it be separated, while guarantee film easy opening, can also the hardness of enhanced film, reduce the production cost of film; Erucamide slip agent is added in technique of the present invention, one deck lubricating film can be formed, thus avoid high polymer adhesion each other itself, friction after reduction resin melting between molecule, the phenomenon of skidding when like product simultaneously can be avoided preferably to adhere to screw rod and cause extruding raw material, improves processing characteristics, boost productivity, reduce melting viscosity, increase Resin Flow, give the surface property that goods are splendid.
