Description
Technical field
The present invention relates to the technical fields of casting films, more particularly, to a kind of high resiliency casting films and its preparation and application.
Background technique
Casting films are that a kind of tensionless winkler foundation of quenching production, the cast film of non-directional are cast by melt, are widely used in
The fields such as textile, fresh flower, food, commodity packaging.
Currently, the most common swimming suit fabric is following three kinds: Du Pont's Lycra, polyamide fibre and terylene.Du Pont's Lycra is suitable for more
One-piece swimsuit, polyester fabric compared with Du Pont's Lycra fabric, sturdy degree not enough, but elasticity with pliability be it is equal,
For the most common fabric；The swimming suit elasticity of polyester fabric is small, is typically designed as split type swimming suit.With the development of the times, swimming suit
Pattern it is also more and more diversified, people are also studying new swimming suit fabric constantly to meet the market requirement.
A kind of casting films material excellent, frivolous as elastic force has the potential quality for being applied to swimsuit field, however, due to
Elastic force is inadequate, seriously limits it in the development in swimsuit field.Therefore, elastomeric casting films can be used as one kind of swimming suit fabric
New direction has certain Research Prospects.
Summary of the invention
The purpose of the present invention one is to provide a kind of high resiliency casting films, has the advantages that elastomeric.
Above-mentioned purpose of the invention has the technical scheme that
A kind of high resiliency casting films, in parts by weight, prepare raw material include 6-11 parts of LDPE, 15-23 parts of LLDPE,
30-45 parts of HDPE, 8-12 parts of PP, 3-5 parts of metallocene PE, 0.5-2 parts of lubricant, 8-15 parts of elastomeric reinforcing material, resist
4-8 parts of microbial inoculum；Wherein elastomeric reinforcing material includes 5-10 parts of EVA, 8-15 parts of TPU, 6-13 parts of EAA；Antibacterial agent includes that tea is more
0.5-3 parts of phenol, 1-5 parts of chitin fiber.
The present invention is further arranged to: in parts by weight, preparing raw material further includes 2-6 parts of Masterbatch.
By using above-mentioned technical proposal, the casting films that multiple color can be made in Masterbatch are added, expand the choosing of consumer
Select range.
The present invention is further arranged to: in parts by weight, prepare raw material include 9 parts of LDPE, 19 parts of LLDPE,
38 parts of HDPE, 10 parts of PP, 4 parts of metallocene PE, 1.5 parts of lubricant, 12 parts of elastomeric reinforcing material, 6 parts of antibacterial agent, color masterbatch
4 parts of grain.
By using above-mentioned technical proposal, a variety of polyethylene are chosen, polypropylene is primary raw material, and adds elastic strengthening material
Material improves the elasticity of polymer；HDPE first and LLDPE has more excellent tensile strength and toughness, and heat-resisting resistance to, cold-resistant
Better performances, suitable for production swimsuit so that people swim in the water；Secondly, the permeability of HDPE is smaller, water imbibition is low, improves
Comfort when swimsuit is worn under water；PP is the most light general-purpose plastics of quality, and the PP that certain component is added can reduce polymer
Weight, polypropylene flexural fatigue resistance also with higher when needing to store clothing, can fold arbitrarily, be easy to use；And PP
Moise-heat sterilization also can be used in product, wears after swimsuit swims in swimming pool, also clothing can carry out disinfection, kill the thin of clothing surface
Bacterium etc.；Matching between HDPE, LLDPE, PP is so that polymer has more excellent tensile property.
The elasticity of polymer can be improved in elastomeric reinforcing material.Wherein, EVA and TPU have high flexibility, EVA also have every
Heat heat preservation, cold-resistant, water resistance, when its water resistance is made in water, swimming suit always with the skin attachement of human body；Strictly
The component for controlling EVA and TPU, can be improved the elasticity of polymer, so that elasticity reaches the degree suitable for human body dress；To improve people
Comfort when wearing swimming suit, and EAA is added into elastomeric reinforcing material, EAA has more excellent gas-premeable, and has
There is certain caking property, gluing between elastomeric reinforcing material and polymer also can be improved in the gas permeability that polymer not only can be improved
Knot property, to ensure that elastomeric reinforcing material can play a role；
In addition, antibacterial agent is added in raw material to improve the safety in swimming pool went swimming；Tea polyphenols have sterilization
Effect, to pathogen, virus have it is apparent inhibit and killing effect, can also reduce the ultraviolet radiation in daylight to skin
Damage；Chitin fiber is non-stimulated, has certain anti-infectious function；The chitosan of small molecule has protonation
Ammonium, the cell membrane of protonation ammonium and bacterium with negative electrical charge act on, absorption and coagulation bacterium, while penetrating cell wall enters cell
It is interior, upset bacterium metabolism and synthesis and have antibacterial action；Chitin fiber and tea polyphenols are used cooperatively so that poly-
Closing object has stronger inhibiting effect to various bacteria, and swimsuit is personal clothing, with greater need for the growth for inhibiting bacterium.
In addition to this, it is also added with metallocene PE and lubricant, when producing casting films, metallocene PE and lubrication
Agent can also strengthen the extrusion processability energy of film while keeping excellent film performance.In conclusion strict control is a variety of
The higher casting films of elasticity can be made in the ratio of polyethylene, polypropylene elastomeric reinforcing material and antibacterial agent, to be used for the quality of production
Lighter swimming suit is applied to swimsuit field.
The present invention is further arranged to: it is castor oil that the lubricant, which is selected,.
The present invention is further arranged to: in parts by weight, elastomeric reinforcing material includes EVA8 parts, 12 parts of TPU,
EAA10 parts.
The present invention is further arranged to: in parts by weight, antibacterial agent includes 1.8 parts of tea polyphenols, chitin fiber 3
Part.
The purpose of the present invention two is to provide a kind of application of high resiliency casting films, is applied to swimsuit.
A kind of casting films material excellent/frivolous as elastic force has more frivolous compared to existing fabric in the market
Advantage, the swimming suit lighter weight of production are stored and are carried convenient for consumer.
The purpose of the present invention three is to provide a kind of preparation method of high resiliency casting films, comprising the following steps:
S1: mixing and extrusion plasticizing: comparing according to parts by weight, each raw material for preparing is put into extruder after mixing, will be squeezed
The temperature of machine is adjusted to 160-170 DEG C out, and keeps 25-35min, is plasticized, and squeezes；
S2: it squeezes out curtain coating: being successively attached in sequence, filters, is cast process, wherein the temperature of Joining Technology is 195-
205℃；The temperature of filtering technique is 255-265 DEG C；The temperature of curtain coating is 220-230 DEG C；
S3: calendering sizing: temperature is set as 20-30 DEG C of rubber rollers, is embossed 60-65 DEG C of steel rod, draw-down rate 65-78m/min；
S4: corona, trimming winding: carrying out trimming winding after sided corona treatment, the tension of winding process is 30-35N.
In conclusion advantageous effects of the invention are as follows:
1. adding elastomeric reinforcing material in raw material in preparing, and the proportion between strict control EVA, EAA, TPU, it is ensured that casting films
Outside the performance of itself, the elasticity of casting films is substantially increased, elasticity also can be improved in the gas permeability that polymer not only can be improved in EVA
Caking property between reinforcing material and polymer, to ensure that elastomeric reinforcing material can play a role；
2. being used cooperatively so that casting films have stronger inhibiting effect to various bacteria for chitin fiber and tea polyphenols, reduces
The risk being infected by bacterial；
3. by casting films be applied to swimsuit field, the swimming suit of production have the characteristics that it is frivolous, convenient for consumer storage with carrying.
