After being coated at high temperature, the melamine fumiture surface paper coated with the ultrasonic violet curing coating obtained through the invention of the invention has the advantages of good adhesion of the surface ultrasonic violet curing coating and the melamine layer and good recoatability of the ultrasonic violet curing coating surface, and has better recoatability than the prior commonly used melamine fumiture surface paper.
Description
Technical field
The invention belongs to architectural decoration material field, particularly the surface is coated with melamine paper of ultraviolet-curing paint and preparation method thereof by what coating ultraviolet-curing paint (abbreviation UV coating) obtained.
Background technology
At present, the general preparation method of melamine paper is that common paper is dried behind the single-steeping in melamine glue, and then is coated with one deck melamine glue, oven dry again at the paper front and back difference secondary of single-steeping melamine glue.Melamine paper is mainly used in overlaying of dalle surfaces such as density board and shaving board, and the sheet material after overlaying is widely used in making various furniture, cabinet and other house decorative material.Melmac is the highly stable resin of a kind of chemical property, since melamine glue film-forming after high temperature overlays of melamine paper surface precoating, the coating of formation compact structure, and general coating is difficult to adhere to the non-constant of recoatability on its surface.Chinese patent CN 101074277A discloses a kind of acrylic ester high molecular type coating that contains acroleic acid esterification that is used for the melamine paper external coating, this method is to overlay the plate surface application of melamine paper, this also is the method that the present suitability for industrialized production of the industry generally adopts, earlier overlaying plate surface application one deck adhesion primer of melamine paper, and then at adhesion primer external coating topcoat.However, the topcoat on the sheet material that this method is made is still undesirable at the adhesive force on melamine paper surface, along with the growth of service time, and the possibility that surperficial paint film has cracking and comes off.
Summary of the invention
The objective of the invention is in order thoroughly to solve the recoatability problem of melamine paper, a kind of recoatability is provided good surface coated has the melamine paper of ultraviolet-curing paint.
A further object of the present invention provides the preparation method that a kind of surface coated has the melamine paper of ultraviolet-curing paint.
The present invention will be applied to the one side of melamine paper in advance with the good ultraviolet-curing paint of melamine glue adhesive force, be affixed on dalle surfaces such as density board or shaving board again through high-temperature high-pressure, and then, can solve the adhesive force problem of finish paint coating and melamine paper well at the ultraviolet curable coating external coating finish paint of precoating.Because the ultraviolet-curing paint described in the present invention is applied to the one side of the common paper of single-steeping in melamine glue in advance, the one, melamine glue does not also overlay through high temperature, there is not film-forming, surface-activity is higher, ultraviolet-curing paint described in easier and the present invention adheres to, the 2nd, behind the common paper single-steeping melamine glue, glue-line is thinner, be penetrated into the fibrous inside of paper after the ultraviolet-curing paint application described in the present invention easily, thereby better adhesion is arranged with paper, the 3rd, when high temperature overlays, the ultraviolet curable coating on melamine paper surface and melamine glue and paper fibre have stronger physical absorption and hydrogen bond action, thereby strengthen the ultraviolet curable coating of precoating and the adhesive force of melamine glue, thoroughly solve the recoatability problem of melamine paper.
Simultaneously, ultraviolet-curing paint described in the present invention is a kind of environment-friendly and green coating that does not contain the volatile organic compound, it is fast that ultraviolet light polymerization has curing rate, energy consumption is low, advantages such as equipment investment is low, and the place area occupied is little, and paint film property is good, therefore, adopt ultraviolet light polymerization explained hereafter melamine paper to have more advantages.
