The preparation method comprises the following steps: adding initiator, emulsifier and softened water in a pre-emulsification tank to stir for 20-30min, then dropping pH buffer regulator, soft monomer, hard monomer, functional monomer, functional additive and softened water for 3-4h by using two pumps separately, then heating the reaction tank to 80-90 DEG C to perform a reaction, adding hard monomer in the reaction tank when 1/2-2/3 of the reaction is performed; after dropping, continuously reacting for 1-2h while keeping the temperature of the reaction tank to 80-90 DEG C, reducing the temperature of the reaction tank to 40-50 DEG C, canning and discharging. The waterborne translucent composite paper priming gloss oil is characterized in that the gloss oil is completely waterborne, does not contain organic solvents such as benzene and 1,1-diethoxyethane, has high color fastness and brightness and can not react with bronze powder.
Description
Technical field
The present invention relates to a kind of coating composition, relate in particular to a kind of composition and preparation method of waterborne translucent composite paper priming gloss oil.
Background technology
Though traditional plastic film composite sheet has glossiness height, advantage such as attractive in appearance, durable, but be unfavorable for the recycling of waste paper, environment is polluted, therefore, present package paper is just progressively used the glazing paper of easy pulverizing regeneration instead, serious because of the solvent evaporates environmental pollution in the operation of solvent-borne type oil polish glazing again, thereby environment for use close friend's water-based gloss oil is more and more favored.But problems such as general water-based gloss oil all exists some problems in application, little such as initial bonding strength, and resistance to water and alkali resistance difference and adhesion strength are not high.Water-based gloss oil also has a more scabrous problem in application, be exactly the emulsion that water-based gloss oil is generally white, and this has just influenced the glossiness of gloss oil, thereby has influenced the class of packaging material.
Chinese patent CN101275005 discloses a kind of water-based gloss oil of preparation method, acrylic emulsion and gained of nucleocapsid structure acrylic emulsion, the production cost of the acrylic emulsion that this invention obtains is low, mechanical performance and stable storing performance are all fine, but gloss oil adhesion strength that this invention obtains and transparency are not very desirable.
Chinese patent CN1405250 discloses a kind of composition and preparation method of water-based compound paper-background glazing oil, and the adhesion strength of the water-based gloss oil that this invention makes is strong, but production technology is more loaded down with trivial details, and production equipment is required than higher.
In order to address the above problem, the present invention is achieved through the following technical solutions:
The present invention improves the cohesive strength of emulsion by adding a certain amount of cross-linking monomer; Add some function additives, improved the glossiness of emulsion; Change production technology, improved the character of emulsion effectively, improved the stability of emulsion, and obtained translucent emulsion.Environment-protecting asepsis of the present invention, the relative clean environment firendly of the composition of translucence emulsion not only can reduce in the production process people's injury, has also reduced the dangerous hidden danger in the use, is the ideal substitute of white emulsion shape gloss oil in the market.
Summary of the invention
The objective of the invention is to provide a kind of composition and preparation method of waterborne translucent composite paper priming gloss oil for the some shortcomings of improving existing market oil polish existence.
In order to solve the problems of the technologies described above, the present invention realizes by following steps:
A kind of waterborne translucent composite paper priming gloss oil is characterized in that each component and degree are respectively soft monomer 10-20%, hard monomer 25-30%, function monomer 2-4%, emulsifying agent 0.5-2%, initator 0.08-0.3%, PH buffering conditioning agent 0.2-0.6%, function additive 0.5-1.2%, demineralized water 45-55%.
