Description
Technical field
The present invention relates to coating technology, particularly a kind of compound epoxy flooring coating based on modified resin and preparation method thereof.
Background technology
At present, terrace paint has been the recognition and acceptance of users institute gradually, just is being widely used in hospital, parking lot, vault, playground, workshop, pharmaceutical factory, apartment or the like civilian and Industrial buildings and facility.
According to the filmogen classification, terrace paint can be divided into kinds such as mineral-type, polyurethanes, polyureas, acrylic acid or the like, epoxies.Every kind of terrace paint all has its advantage and defective.For the epoxies terrace, defective such as exist acid resistance and weathering resistance is poor, and matter is crisp easily to be split, not shock-resistant.
Present terms of settlement, the one, utilize the snappiness of solidifying agent to carry out modification, the 2nd, the method that adopts chemical modification is to redesign of Resins, epoxy molecule and modification.The first method effect is limited, is subjected to the restriction of solidifying agent molecular structure.Second method need be carried out in the synthetic workshop of resin, has not only limited the coating material production producer that lacks synthetic workshop, and has lacked the handiness at terrace paint different application occasion.
Therefore be necessary to provide a kind of modified resin that utilizes, only by simply mixing the new type compound epoxy flooring coating that just can overcome Resins, epoxy terrace paint shortcoming with Resins, epoxy.
Summary of the invention
The purpose of this invention is to provide a kind of compound epoxy flooring coating.
The present invention adopts modified resin such as C9 petroleum resin, Gum Rosin and Hydroxylated acrylic resin to mix with Resins, epoxy, prepares that weather resistance is good, hardness is high, shock resistance, compound epoxy flooring coating that wear resistance is good.
