Natural or synthesis a, organic or inorganic substance together, adhesive be suitable for different materials, different thicknesses,
The connection of ultra-thin specification and complex component, the generally existing antioxygenic property of existing adhesive on the market is poor, raw material components are more, system
Make problem cumbersome, at high cost, that bonding property is poor, and since most of adhesives do not have restraining and sterilizing bacteria ability, adds glue
The particularity of glutinous agent use environment, so that adhesive is easy to by various bacteria attacks, such as Escherichia coli, coliform 0-157, Portugal
Grape coccus, salmonella, the root fungus that rubs etc. are based on this but also its bonding property is had a greatly reduced quality, and it is poly- to design a kind of antibacterial environment protection type
Urethane adhesive or necessary.
Summary of the invention
In view of the shortcomings of the prior art, object of the present invention is to be to provide a kind of antibacterial environment protection type polyurethane gluing
Agent, component is simple, and preparation is easy, and antioxygenic property is good, has stronger restraining and sterilizing bacteria effect, and at low cost, easy to spread to make
With.
To achieve the goals above, the present invention is to realize by the following technical solutions: antibacterial environment protection type polyurethane glue
Glutinous agent, formula include following components: polyether polyol 45-60%, toluenediisocyanate 25- by weight percentage
35%, UV resistant agent 0.5-3%, antioxidant 0.2-2%, antibacterial shellfish powder 10-15%.
The preparation process of antibacterial environment protection type polyurethane adhesive are as follows: polyether polyol 45-60% is warming up to 110-120
DEG C, it is dehydrated 2 hours, then cools to 30-45 DEG C again, toluenediisocyanate 25-35% is added after mixing evenly, is warming up to
80-100 DEG C and heat preservation 4 hours, 0.5-3% UV resistant agent, 0.2-2% antioxidant, addition when cooling to 40-50 DEG C is added
The antibacterial shellfish powder of 10-15% is cooling.
Preferably, the antibacterial shellfish powder uses 100% Hokkaido scallop shell, the preparation process of antibacterial shellfish powder are as follows: will
Scallop shell is put into pyrolysis furnace, carries out burning processing with 1000 DEG C of high temperature, and the calcium carbonate of shell is processed as calcium oxide,
Calcium oxide has had certain antibacterial action, so that calcium oxide is become anti-microbial property higher through adding water process again in the fabrication process
One calcium hydroxide of antibacterial agent, to smelly eliminating, sterilize, prevent oxidation have good effect.
Beneficial effects of the present invention: (1) component is simple, and preparation is easy, and at low cost；
(2) antioxygenic property is good, and corrosion resisting property is good, and adhesion strength is high, guarantees its bonding property；
(3) have stronger restraining and sterilizing bacteria effect, various bacteria attacks can be resisted, to Escherichia coli, coliform 0-157,
Staphylococcus, salmonella, the root fungus that rubs have stronger bactericidal effect, prolong the service life；
(4) nontoxic, safety and environmental protection.
