Description
Technical field
The invention belongs to tackiness agent preparing technical field, specifically about a kind of preparation method of soybean oil based two-component keel tackiness agent.
Background technology
Along with the raising day by day of standard of living, constantly pursue comfortable people, also perfect further to the requirement on floor, floor is a very important part in house decoration.Timber floor, because its annual ring, texture often can become the picture of a width beauty, just gives a kind of back to nature of people, the sensation of recovering one's original simplicity and being loved by the people.And the feature such as timber floor itself has that quality is slim and graceful, ultimate compression strength is large, easy to process, good heat preservation performance makes it once become first of people's house ornamentation to select.
Keel laying method is that floor is the most traditional, laying method the most widely.Keel will in ground perforating when mating formation, and with wood particle as floor leveling, then fix rough ground with iron nail, finally floor flooring nail is fixed on keel.This method not only because of in ground perforating, producing very large noise, and can damage the structure of cement flooring, leaves hidden danger to safety.If can be bonded on cement flooring by keel with tackiness agent thus, avoid perforating on cement flooring, more more options will be brought to house ornamentation.
Tackiness agent is in the market of a great variety, but the material used is base-material mainly with formaldehyde greatly, and as urea-formaldehyde resin, resol or terpolycyantoamino-formaldehyde resin etc., these products in use constantly volatilize formaldehyde, have had a strong impact on the health of people.Therefore, people more and more tend to the aldehyde-free cement using toxicological harmless, renewable source production.On the other hand, because tackiness agent has very strong dependency to petroleum products, along with the shortage of world oil, the rise of oil price, makes the market cost increase of tackiness agent, bogged down in crisis.
Summary of the invention
In order to overcome the many disadvantages of above-mentioned tackiness agent, and searching renewable resources carrys out petroleum replacing, and the present invention, using epoxy soybean oil as the raw material preparing tackiness agent, has the advantages such as cheap and environmental protection.
The preparation method of described a kind of soybean oil based two-component keel tackiness agent of the present invention, concrete operation step is as follows:
Step a, easy volatile polyamine compounds is joined in the reactor with whipping appts, the acetone soln of a certain amount of epoxy alkane is dripped in room temperature downhill reaction still, room temperature reaction for some time, boil off acetone, difficult volatile polyamine compounds can be obtained;
Step b, by epoxy soybean oil with obtain difficult volatile polyamine compounds with certain amount of substance than mixing, react 4 ~ 9h at a certain temperature, decompression is sloughed small molecules and is namely obtained adhesive A component;
Step c, adhesive A component will be obtained mix according to certain mass ratio with B component, use in 3 ~ 5h.
In step a, easy volatile polyamine compounds is quadrol or diethylenetriamine.
In step a, easy volatile polyamine compounds is 1: 0.9 ~ 1.5 with the amount of substance ratio of epoxy alkane.
Step a alkylene oxide hydrocarbon is propylene oxide or epoxy chloropropane or oxyethane.
Step a alkylene oxide hydrocarbon and easy volatile polyamine compounds reaction times are 4 ~ 5h.
In step b, the epoxy radix of epoxy soybean oil per molecule is 3.5 ~ 4.2.
In step b, epoxy soybean oil is 1: 3.0 ~ 4.2 with obtaining the amount of substance ratio that difficult volatile polyamine compounds reacts.
Temperature of reaction in step b is 90 ~ 110 DEG C.
In step c, B component is epoxy resin E-44 or E-51 or E-54 or ethylene glycol diglycidylether or tirethylene glycol diglycidylether.
In step c, the mass ratio of adhesive A component and B component is 1: 0.5 ~ 1.0.
Advantage of the present invention and innovative point are: 1. easy volatile polyamine compounds and epoxy alkane are reacted, and the volatile polyamine compounds of difficulty of generation has the features such as little, the difficult volatilization of smell.2. using epoxy soybean oil as synthesis material, environment protection and economic Sustainable development is conducive to.
