Abstract
The invention discloses a waterproof coating for water-based paperboards and a preparation method thereof. The coating is mainly prepared from water, an acrylate emulsion, a paraffin emulsion, an epoxy resin, a film forming additive, a flatting agent and other additives. Through the compounding of the paraffin emulsion and the acrylate emulsion, the advantages of the two emulsions are integrated, so that the glossiness, adhesion, abrasion resistance and water repellency of the waterproof coating are maximally increased; due to the addition of the epoxy resin and a drier, the water repellency, coating hardness and surface drying time of the coating can be further improved; and the waterproof coating disclosed by the invention, as a water-based resin coating, is solvent-free, non-toxic, green and environment-friendly in the process of production, and therefore, the waterproof coating has important economical and social benefits.
Description
Technical field
The present invention relates to water-base resin technical field of coatings, especially relate to a kind of water-based cardboard water-repellent paint for paperboard surface waterproof and preparation method thereof.
Background technology
Water-base resin waterproofing agent has advantage that is nontoxic, tasteless, that do not fire, safe and reliable, can use at normal temperatures, and free from environmental pollution, simple to operate, thus emulsion type resin waterproofing agent at home and abroad obtains a wide range of applications in recent years.
At present, what cardboard sector application was the widest is paraffin wax emulsions type water-repellent paint, and this is mainly because it has the advantage that preparation technology is simple, cost is low, lotus leaf effect is excellent.But this paraffin wax emulsions water-repellent paint also also exists that weatherability difference, adhesive force are low, the shortcoming such as wear no resistance simultaneously, be difficult to realize long moistureproof and waterproof.In addition, also have and use emulsion acrylic resin as water-repellent paint, although this emulsion acrylic resin coating possesses excellent weatherability, heat resistance, ABRASION RESISTANCE, and also possess as coating that adhesive force is high, the advantage of environmental protection, but there is water resistance deficiency, the price shortcoming such as costly equally in it, therefore, be difficult to apply on a large scale in water-repellent paint field.
Summary of the invention
Technical problem solved by the invention is to provide a kind of water-based cardboard water-repellent paint, to solve the shortcoming in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of water-based cardboard water-repellent paint, comprises the raw material of following parts by mass:
Paraffin wax emulsions 20 parts ~ 100 parts
Acrylic ester emulsion 70 parts ~ 120 parts
20 parts ~ 60 parts, water
Epoxy resin 4 parts ~ 20 parts
Coalescents 2 parts ~ 10 parts
Levelling agent 0.2 part ~ 2 parts
Other auxiliary agent 10 parts ~ 30 parts
Wherein, other auxiliary agents are the antifreezing agent of arbitrary proportion, drier, defoamer, preservative agent and auxiliary rheological agents.
In the present invention, described acrylic ester emulsion is any one and any combination in benzene emulsion, acrylate and vinyl acetate emulsion, pure-acrylic emulsion, Silicone acrylic emulsion, methacrylic acid emulsion.
In the present invention, described levelling agent is modified organic silicon class or modified acrylic acid levelling agent.
In the present invention, described coalescents is lauryl alcohol ester.
A preparation method for water-based cardboard water-repellent paint, comprises following step:
First above-mentioned water, defoamer, coalescents, paraffin wax emulsions, acrylic acid ester emulsion are added in stainless steel agitator, under normal temperature, mix 10 ~ 15min.
Slowly add epoxy resin in solution upon mixing to stir, and keep stirring 5min ~ 10min.
Add levelling agent, drier, preservative agent and auxiliary rheological agents respectively in proportion, after stirring 3 ~ 5min, filtration, discharging both obtain finished product.
Advantage of the present invention and beneficial effect are:
(1) combine the advantage of paraffin water-proof emulsion and polyacrylic water-proof emulsion, make complex emulsions have excellent water resistance, adhesive force, anti-wear performance, weatherability etc.
(2) add cross linking of epoxy resin modified, the water proofing property of complex emulsions, hardness of film, adhesive force, solvent resistance etc. are improved further; Add after drier, the dried coating film time significantly reduces, and the resistance to impact of film, pliability, hardness also can be improved in addition.
(3) cost is lower, preparation technology is simple, stable storing, environmental protection, there is huge economic benefit.
Detailed description of the invention
Give an actual example below and describe the present invention.
Comprise the raw material of following parts by mass:
Paraffin wax emulsions 60 parts
Benzene emulsion 100 parts
Epoxy resin 10 parts
30 parts, water
Levelling agent 0.6 part
Lauryl alcohol ester 4 parts
Talcum powder (drier) 6 parts
Ethylene glycol 5 parts
KF88 (preservative agent) 0.2 part
Mineral oil antifoam agent 0.002 part
AP-425(auxiliary rheological agents) 0.5 part
During preparation, first above-mentioned water, defoamer, coalescents, paraffin wax emulsions, benzene emulsion are added in stainless steel agitator, mix 10min under normal temperature, slowly add epoxy resin in solution upon mixing and stir, keep stirring 8min, then ethylene glycol, levelling agent, talcum powder, lauryl alcohol ester, KF88, mineral oil antifoam agent is added in proportion respectively, stir 5min, after finally AP-425 being converted a small amount of water, slowly add, after stirring 3min, filtration, discharging both obtain finished product.
This dope viscosity is 300mpa.s, also can spray production by manual brushing, can surface drying in 30min under room temperature, and easy to operate, cost is lower.It can form the waterproof membrane of one deck light in paperboard surface, have significant lotus leaf effect, more than water-proofing time 10d, and crocking resistance is general, energy high-low temperature resistant (-10 DEG C ~ 80 DEG C), acid and alkali-resistance.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
