Abstract
The invention relates to a bandage and adhesive tape manufacturing method comprising following steps of: A, selecting a base material; B, coating a foam coating provided with low surface energy and generated by a foam generator on the base material by using the foam generator and a foam exertion device with a foam coating method; and C, coating adhesives on the base material. Products prepared by the foam coating method have good air permeability, even coating, large coating quantity, easy control and low cost, can prevent the permeation of the adhesives and a sizing agent, and has large coating and film covering rate and soft hand feel.
Description
Technical field
The present invention relates to the manufacture method of a kind of binder, adhesive tape, especially a kind of foam coating legal system is equipped with the method for binder, adhesive tape.
Background technology
At present the adhesive gluing and the sizing technique of binder and adhesive tape have six kinds: a kind of is aqueous or organic solvent adhesive, the direct coating of slurry, is called for short directly being coated with; Second kind is spray glue; The third is a blade coating; The 4th kind is to shift to be coated with; The 5th kind is dip-coating; The 6th kind is obliterating.
Directly coating is influenced by the uniformity of base material thickness, and glue-spread is wayward.
Spray-bonding craft adhesive, pulp particle are splashed everywhere, and abnormal smells from the patient is big, and waste is serious, and environmental pollution is serious, produce occupation disease and poison and occupation disease hidden danger.
Foam finishing technology is the influence that is subjected to the energy crisis seventies in 20th century, a kind of low feeding that develops rapidly abroad, high energy-conservation dyeing and finishing process technology.It is that gas is fed in the working solution, shear the bulky foam that the back generates numerous micro-bubbles compositions by mixing, substitute the water in the dyeing and finishing bath, be applied on the fabric then, make the liquid carrying rate of fabric drop to 15-30%, thereby can save the drying energy consumption more than 50% by traditional 60%-80%.It reduces plurality of advantages such as waste water, toxic emission in addition in addition, helps environmental conservation greatly, therefore causes people's common concern.
In recent years; shortage along with energy shortage and water resource; people's environmental consciousness is strengthened greatly; country has strengthened the protection to natural environment; policy energy-conservation, that lower consumption, reduce discharging that strictness is carried out; each enterprise is reducing production costs, is reducing pressure multiplier aspect energy resource consumption and waste water, the toxic emission, and these factors make the Technology of this energy-saving effect highly significant of foam finishing be subject to people's attention again and favor.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, binder, the adhesive tape manufacture method of a kind of novel environment friendly, even, quantitative coating binder and low-surface-energy material is provided.
Important aspect is that slurry and adhesive with aequum is coated on the various base materials equably in the production of present various binder and adhesive tape; Another aspect is to be coated with various slurries and adhesive effectively.When the slurry that uses and adhesive are too much, not only increased cost, and redundant sizing agent and adhesive can cause environmental pollution, also need to take measures to reduce the influence of coating process simultaneously to environment.
Foam finishing technology is that gas is fed in the working solution, shear the bulky foam that the back generates numerous micro-bubbles compositions by mixing, substitute the water in the dyeing and finishing bath, be applied on the fabric then, make the liquid carrying rate of fabric drop to 15-30%, thereby can save the drying energy consumption more than 50% by traditional 60%-80%.It reduces plurality of advantages such as waste water, toxic emission in addition in addition, helps environmental conservation greatly, therefore is incorporated into the various application of textile dyeing and finishing industry in recent years energetically, but does not appear in the newspapers in the utilization of binder and adhesive tape manufacturing.
Foam is the heterogeneous dispersion of gas dispersion in liquid, and gas is decentralized photo, and liquid is disperse medium.Prepare in the foamy process, the bubble in the liquid easily forms bubble coalescence thing---the foam that the liquid film that constitutes with small amount of liquid separates gas on liquid level under the effect of density contrast.Aerated fluid is the bubble dispersion of gas composition, has high surface free energy, is thermodynamic unstable system.
The foam coating method is meant by foam maker and foam applicator the foam single or double that foam maker produces is applied on the various base materials.
The objective of the invention is to finish by following technical solution, the manufacture method of a kind of binder, adhesive tape, described manufacture method may further comprise the steps:
A, choose base material;
B, utilize the foam coating of the low-surface-energy that the foam coating method produces foam maker with foam maker and foam applicator to be coated in the basic unit;
C, with adhesive coated on base material.
Described foam coating mesostroma is to be made by the material of adhesive and low-surface-energy, and contains abscess, and this foam coating can be produced by following steps:
The mixture of a, the material that obtains adhesive and low-surface-energy and liquid, water;
B, evaporating liquid or partially liq are to form the space in mixture, this space has formed the interior zone of the abscess of substrate.
Contain the foams component in the described foam coating, described foams component comprises the substrate of polymeric material, and described foams component can be produced by following steps:
I, obtain polymeric material;
Ii, in described polymeric material, introduce gas with chemistry or physics mode.
Described base material can be cotton or non-woven fabrics or acetate fibres or non-woven paper or foam.
Described low-surface-energy material is meant that surface energy is lower than the material of 100mN/m.
The material that described surface energy is lower than 100mN/m can be acrylate or silicon compound or silicon polymer or the fluorocarbon resin that acrylate or fluorine replace, but one of skill in the art knows that low-surface-energy material is not limited only to described instantiation.。
Described adhesive can be Heveatex adhesive or rubber polymer adhesive or acrylate adhesive or the adhesive that can produce foamy other types with technology of the present invention.
The present invention adopts the product good permeability of foam coating method preparation, and coating is even, and coating weight is big and easy to control, and production cost is low, can prevent the infiltration of adhesive and slurry, and coating and film hiding rare are big, soft.
