Description

Agricultural machinery sealing wax and preparation method thereof
Technical field
The invention belongs to technical field of coatings more particularly to a kind of agricultural machinery sealing wax and preparation method thereof.
Background technology
China is used as grain big country, the use of farm implements to have long history, and in today's society, agricultural realizes the modern times Change, large-scale Farming and harvesting have large-scale farm machinery, this is the embodiment of social progress, but traditional agricultural machinery There is no being substituted under the tide of mechanization, because traditional agricultural machinery is easy to use, flexible, it is convenient for carrying, in grain-production It is essential, and with the present improvement of people's living standards, agricultural machinery is applied to gardens gardening, gourd, fruit and vegetable, flowers kind The numerous areas such as plant, people plant a little satisfactions and become a kind of fashion from the vegetables of household in a little flowers and plants of Around the house kind, It allows people's more love life, gets close to nature, enjoy health.So modern agricultural machinery goes back quilt in addition to maintain traditional use function The label of culture is sticked, object of the good agricultural machinery even as collection is also particularly important so for its appearance.Agriculture The appearance of machine depends greatly on the coating on its surface, this just proposes strict requirements, mesh to the coating in the field Preceding coating common problem is:
(1) existing with painting based on solvent type, it needs to solve the problems, such as that pollution is big, unsafe;
(2) there are apparent gaps with solvent based product for the appearance properties such as richness of existing water paint product;
(3) the dip-coating effect of existing water paint product is difficult to coordinate blistering and increase the balance of coating thickness, that is, works as coating When viscosity is low, it is not likely to produce blistering, but paint film is very thin, cannot met the requirements, vice versa;
(4) existing water paint product throwing slot rear stability has to be hoisted.
Invention content
Technical problem to be solved by the invention is to provide it is a kind of environmental protection, compact in paint film stable and uniform agricultural machinery sealing wax, It can solve the problems, such as existing agricultural machinery paint.
In order to solve the above technical problems, the technical solution used in the present invention is:A kind of agricultural machinery sealing wax, formula is by weight Percentage calculation is as follows:Water-base resin:40-60 parts of water-based acrylic resin, 10-15 parts of water-compatible amino resin;Auxiliary agent:Environmental protection is molten 10-20 parts of agent, 0.2-0.4 parts of antifoaming agent, 0.2-0.5 parts of levelling agent, 0.3-0.6 parts of substrate wetting agents, is gone 1-5 parts of neutralizer 40-60 parts of ionized water.
Further, the water-based acrylic resin is Eudragit E A1621A.
Further, the water-compatible amino resin is Amino resin 5717W, one kind in cyanogen spy 303 or two Kind.
Further, the environmentally friendly cosolvent is two or three in ethylene glycol, propylene glycol monomethyl ether, alcohol.
Further, the neutralizer is one or both of dimethylethanolamine, AMP-95.
Further, used additives are made in the defoaming that used additives TEGO-902w, BYK are made in the deaeration that the antifoaming agent is TEGO Two kinds of mixtures of BYK-024.
Further, the levelling agent is one or both of BYK-331, TEGO-4100.
Further, the substrate wetting agents are one or both of BASF-3322, TEGO-270.
It is using agricultural machinery advantageous effect caused by sealing wax provided by the present invention:
(1) water-base resin system is selected, VOC≤80g/L, smell is very low, more environmentally-friendly;
(2) different types of antifoaming agent is selected to be compounded, balance blistering solves system air bubble problem, with asking for film thickness Topic improves film effect;
(3) suitable environmentally friendly solvent compounding is selected, the stability that coating stores in dip-coating paint bath is improved;
(4) water-based acrylic resin and water-compatible amino resin high-temperature cross-linking are selected, compact in paint film degree is improved, is improved plentiful Degree.
The present invention also provides a kind of preparation methods of agricultural machinery sealing wax, can prepare above-mentioned agricultural machinery sealing wax, step is such as Under:
Water-based acrylic resin is added in stock pot according to the raw material proportioning, adds environmentally friendly solvent by step a, It is stirred 2-3 minutes with the speed of 450-500r/min.
Step b is added neutralizer and adjusts pH value, with the speed of 450-500r/min while stirring according to the raw material proportioning Degree stirring 2-3 minutes.
Step c, according to the raw material proportioning, with the speed of 450-500r/min while stirring by amino resins, antifoaming agent, Moistening flatting agent, deionized water are sequentially added into, and are stirred 10-15 minutes with the speed of 1100-1200r/min.
Specific implementation mode
The present invention will be further described in detail with reference to the specific embodiments.
A kind of specific implementation mode of agricultural machinery sealing wax provided in an embodiment of the present invention, formula is count by weight percentage such as Under:Water-base resin:40-60 parts of water-based acrylic resin, 10-15 parts of water-compatible amino resin;Auxiliary agent:10-20 parts of environmentally friendly solvent, in With 1-5 parts of agent, 0.2-0.4 parts of antifoaming agent, 0.2-0.5 parts of levelling agent, 0.3-0.6 parts of substrate wetting agents, deionized water 40-60 Part.
Sealing wax provided in an embodiment of the present invention selects water soluble acrylic acid dispersion and water-compatible amino resin, passes through 120 DEG C High-temperature baking crosslinking curing obtains the water-based stoving paint coating of high glaze, high-decoration, wherein the water paint VOC prepared≤ 80g/L, smell is very low, prevents pollution environment;It selects different types of antifoaming agent to be compounded, solves system air bubble problem; Suitable environmentally friendly solvent compounding is selected, storage stability is improved, improves film effect.
Compared with traditional solvent based coating, water paint has price low, safe to use, saves resource and the energy, subtracts The advantages that few environmental pollution and public hazards, thus have become the Main way of current development coatings industry.Water soluble acrylic acid olefine resin Coating is with fastest developing speed, pollution-free coating that kind is most in water paint.
