Abstract
The present invention provides dedicated sealing wax of a kind of polypropylene plastics and preparation method thereof, the composition of the second resin composition of the first resin and 25-40 weight % that the film forming matter of the dedicated sealing wax of polypropylene plastics is 60-75 weight %.The dedicated sealing wax of polypropylene plastics of the present invention further includes having adhesion promoter, pH adjusting agent, deionized water, cosolvent, dispersing agent, defoaming agent, pigment, anti-settling agent, wetting agent, levelling agent, thickener as needed.Not only adhesive force is strong for the dedicated sealing wax of polypropylene plastics, and drying time is short, and has very high hardness and lower VOC content, easy to use and to the basic nonhazardous of human body.
Description
Technical field
The present invention relates to water paint fields, and in particular to a kind of dedicated sealing wax of polypropylene plastics and preparation method thereof.
Background technique
With the promotion of people's living standard and the continuous development of plastics industry, plastics have become must in people's daily life
Indispensable a part.Polypropylene is general-purpose plastics with the fastest developing speed after polyvinyl chloride, polyethylene, big logical as three
With plastics, yield is increasing, and especially in recent years, people mould polypropylene by versatility polyacrylic crystalline modified research
Expect to rapidly develop to functional plastic and engineering plastics, realizes the functionalization and high performance of general-purpose plastics, widely answered
For industries such as automobile, pipelines.Since polarity of polypropylene is small or nonpolarity, and have the characteristics that crystallinity, surface are smooth, thus it is difficult
To form adhesive force well between paint film and plastic bottom material.
The existing method for solving paint film and polypropylene plastics adhesion problem and measure have following several: can be to its table
The special processing that comes to the surface, such as the oxidation of corona (spark processing) chromic acid, plasma discharge are taken in face, but these processing exist
Very big disadvantage is unfavorable for environmental requirement first is that polluting the environment, and in addition processing cost is also higher, therefore is actually using
On be very limited.And positive solution is to develop a kind of pair of plastic components surface with good adhesive force
Coating.
PP substrate coatings are substantially oiliness PP paint at present, and smell is big, and toxicity is big, influence pole to worker's body and environment
Greatly, smell is small, low low VOC (VOC), therefore the aqueous PP paint of environmental protection comes into being.
Patent application 201510646470.X discloses a kind of automobile exterior PP material special coating and preparation method thereof, but
The harmful substances such as toluene have been used in its priming paint, have caused VOC content higher, and film-forming temperature etc. is higher, the water resistance of sealing wax
It is also required to further increase with adhesive force.

Acrylic acid sodium salt changes and other conditions when not changing, and the adhesive force of sealing wax 1 is significantly better than sealing wax 8, this explanation uses institute of the present invention
The sealing wax that the composition of the first dispersing agent stated and the second dispersing agent composition is prepared as dispersing agent can significantly improve its attachment
Power, and other aspect property retentions are constant.Sealing wax 5 is compared with sealing wax 1, only changes the first dispersing agent and the second dispersing agent
Content, adhesive force also reduce, this illustrates that the first dispersing agent of the invention has within the scope of certain content with the second dispersing agent
There is optimal effect.
Pass through comparative example 1, the test result of embodiment 6 and embodiment 9, it can be seen that when in changing cosolvent
When the content of both dipropylene and dipropylene glycol methyl ether, the drying time of sealing wax 6 is considerably longer than sealing wax 1, this explanation is adopted
The drying time of the sealing wax prepared when using the composition of DPNB and DPM as cosolvent is longer, other performances are held essentially constant.
And having used isopropanol as cosolvent in sealing wax 9, drying time is also longer compared to sealing wax 1, and VOC content is higher, this
The drying time for the sealing wax for the composition that uses the DPNB and DPM of certain content range to form is shown as cosolvent preparing is more
Short, VOC content is lower.
