Abstract
The invention relates to an environment-friendly polyurethane adhesive used for bonding a granulated cork. The invention is characterized in that the environment-friendly polyurethane adhesive consists of MDI, modified MDI, polyether glycol, an antiaging agent and a polymerization inhibitor; according to the mass percentage, the proportion of the MDI, the modified MDI, the polyether glycol and the antiaging agent is 20-30:30-40:30-40:1-5, and the addition of the polymerization inhibitor is 10PPM. When in use, the adhesive and the granulated cork are mixed according to the mass proportion of 1:10-1:5. The adhesive is inodorous and environmentally friendly and can be used at different seasons. When the adhesive is used for bonding the granulated cork, the mold opening time is greatly shorter than the TDI adhesive, and the product property is good.
Description
Technical field
The invention belongs to polyurethane binder field, particularly a kind of environment-friendly polyurethane adhesive that is used for bonding granulated cork and preparation method thereof.
Background technology
At present along with the raising of expanding economy and people's level of consumption, many originally based on outlet cork products also more and more common in the family at home, such as cork flooring, cork ornaments, cork sheet etc.Polyurethane binder of granulated cork is generally the TDI type but existing market is used to bond, and free TDI is more.TDI type cork tackiness agent has the low characteristics such as production, the goods snappiness is good, hardness is moderate that are easy to of viscosity, so light is favored all the time, particularly in product scopes such as cork rod, cork sheet.But along with the enhancing of people's environmental consciousness and the progress of science and technology, the shortcoming of TDI type cork tackiness agent also comes out gradually: have pungent odour, and harmful to HUMAN HEALTH.Because the vapour pressure of TDI is about 1.33Pa for 20 degrees centigrade, cause TDI more volatile, its smell has pungency again, human body sucks NCO-meeting and moisture in the tissue and the reaction of other compositions in the tackiness agent of back, cause sensitization and hormesis, ocular pain occurs, shed tears, symptoms such as conjunctival congestion, cough, uncomfortable in chest, out of breath, asthma, red papule, maculopapule, contact supersensitivity, and just can disperse at the indoor time smell that often needs to grow when waiting place to use.
Summary of the invention
Technical problem to be solved by this invention provides a kind of scentless environment-friendly polyurethane adhesive that is used for bonding granulated cork and preparation method thereof, and this tackiness agent has odorlessness, environmental protection, the short characteristics of molding time.
A kind of polyurethane binder that is used for bonding granulated cork of the present invention, it is characterized in that forming by MDI, modification MDI, polyether glycol, antiaging agent and stopper, according to the mass percent meter, MDI: modification MDI: polyether glycol: antiaging agent: stopper=20-30: 30-40: 30-40: 1-5, the stopper add-on is 10PPM.
Wherein optimized technical scheme is:
Described MDI adopts MDI-100 or/and MDI-50.
Described modification MDI is the MDI of carbodiimide modification.
Described polyether glycol is that 2 functionality and number-average molecular weight are the polyoxytrimethylene polyvalent alcohol of 2000-3000, be selected from DL-2000, DL-3000 or 3 functionality, number-average molecular weight is the polyoxytrimethylene polyvalent alcohol of 3000-6000, as one or more of MN-3050 or 330N.
Preferred 1010 (four [β-(3, the 5 di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol esters) of described antiaging agent or 2, one or both in the 6-toluene di-tert-butyl phenol (BHT).
Described stopper preferably adopts phosphoric acid or Benzoyl chloride.
During use with this tackiness agent and granulated cork according to 1: 10-1: 5 mass ratio mixes.
Preparation the present invention is used for the method for polyurethane binder of bonding granulated cork, it is characterized in that, will be based on adding reactor under the polyether glycol normal temperature of formula ratio, rise to 80 ℃-100 ℃ and stir down, vacuumize dehydration degassing 2-3 hour, be cooled to 10～40 ℃ and add MDI and modification MDI, antiaging agent, stopper, 80-85 ℃ was reacted 2-3 hour, and was cooled to 10～40 ℃ of barrellings.
Advantage of the present invention:
Odorlessness, environmental protection, during with this adhesives granulated cork, the die sinking time shortens greatly than TDI type tackiness agent, and product properties is good.Can use in Various Seasonal.
