Description
Technical field
Adhesive field of the present invention, is related to a kind of self-adhesive and preparation method thereof.
Background technology
Self-adhesive is to bond a class product emerging in agent series products, and prime coats are in packing timbers such as paper, polyester films
The surface of material, when only coated face contacts with each other, can just produce viscosity, and generally, be coated with the surface exhibits of the glue
The cohesive force gone out is smaller, but under the punching press by external force, adhesion strength can increase.Because self-adhesive has the characteristic, at present in state
In the packaging for being widely used in the products such as some sanitary apparatus, medicine, food outside.
Self-adhesive currently on the market is all to use natural rubber for production main material, and not only cost of material is high, and naturally
Contain many harmful chemical substances for being difficult to separate, such as aldehydes in rubber.As the mankind are to the continuous of health requirements
Improve, the use scope of natural rubber self-adhesive is increasingly restricted, and scope is less and less.At present, U.S. government has ordered
Limitation uses natural rubber self-adhesive as medical, food packaging material.Therefore, development and production are new without natural rubber
Glue, harmless people's health type self-adhesive are trends of the times.
Self-adhesive overwhelming majority in the country's is still from external import at present, and development and production work to health type self-adhesive are even more
Blank out.Because there are clearly contradicted, many factories in packaging industry in requirement and current self-adhesive the defect in itself in market
Family can only replace self-adhesive to restricted product using other kinds of adhesive, but product is unable to reach and uses self-adhesive
The good characteristic that is showed of product.Therefore, health type self-adhesive has very big development space.
CN 101676351A disclose a kind of waterborne self-adhesive for water soluble acrylic acid esters paper, mainly by propylene
Acid, butyl acrylate, styrene, functional monomer, initiator, emulsifying agent, buffer, functional aid, pH regulators, softening
Water, surface-active isolation stabilizer, lightweight calcium bicarbonate and 264 dispersions are prepared from by reaction, additionally provide this aqueous
The preparation method of self-adhesive.Although the waterborne self-adhesive is nontoxic, production cost is low, and its viscosity is poor.
The A of CN 105295829 disclose a kind of environment-friendly type high intensity waterproof roll self-adhesive, and it is calculated according to the mass fraction, bag
Include 10-30 parts of s-B-S thermoplastic elastomer (TPE), 30-50 parts of chlorinated paraffin, 30-50 parts of tackifying resin and anti-
0.1-1 parts of oxygen agent.Although the self-adhesive production is simple, without special producing equipment, but 120 DEG C of coatings of low temperature are used, but its
Viscosity still has much room for improvement.
The content of the invention
For existing adhesive exist viscosity difference the problems such as, the invention provides a kind of adhesive and preparation method thereof.
