Description
Technical Field
The invention relates to the field of coatings, and particularly relates to a chlorinated polypropylene coating and a preparation method thereof.
Background
The polypropylene and the polypropylene-containing composite material thereof have the outstanding advantages of low density, good mechanical property, chemical resistance and the like, and are widely applied to internal and external ornaments of automobiles, such as front and rear bumpers, grilles, mud guards, rearview mirrors, instrument panels, rubbing strips and other automobile components. In the exterior trim, the bumper not only has certain decorative effect on the appearance of the automobile, but also has protective effect on the automobile body and pedestrians, and the impact force generated by collision between the automobile body and the pedestrians can be effectively absorbed due to the elasticity of the plastic, so that the injury degree of the pedestrians is minimized as much as possible. The bumper is mainly made of polypropylene, and a layer of coating needs to be coated on the surface of plastic in order to improve the appearance of the plastic bumper and the whole vehicle. The polypropylene material is a non-polar base material and is not compatible with coating components with polarity, so that the adhesion of the coating on the polypropylene base material is poor, and the chlorinated polypropylene resin is usually used for solving the adhesion problem of the polypropylene material. However, since the coating is required to have a good resistance in hot water (the coating is required to be resistant to water at 40 ℃ for 10 days without foaming and without whitening). The automobile exterior bumper coating is matched with different colored paint for decoration, so that the performance has larger difference, particularly matched white paint, the white boiling resistance performance of the polypropylene coating matched with the existing market is inferior to that of the silver paint, and the development of the matched polypropylene primer with the white paint and excellent boiling resistance performance is urgent.
Disclosure of Invention

coumarone resin: 5-20;
dispersing agent: 1-3;
defoaming agent: 0.5 to 2;
organic bentonite: 0.5 to 2;
inorganic pigment: 5-10;
mica powder: 0.05 to 8;
non-floating aluminum paste: 1-2;
leveling agent: 0.5 to 2;

Furthermore, the softening point of the coumarone resin is between 90 and 100 ℃. The coumarone resin is obtained by catalytic polymerization reaction of ethylene tar and carbon nine serving as raw materials, and can be a commercially available product, such as: coumarone resin produced by Shanghai Bao steel.
Further, the chlorinated polypropylene resin and the coumarone resin are blended, and the mass ratio of the chlorinated polypropylene resin to the coumarone resin is (4-6): 1. the chlorinated polypropylene resin provides adhesive force to a polypropylene substrate due to the larger electronegativity of chlorine, and the coumarone resin and the chlorinated polypropylene resin paint have similar solubility parameters and better compatibility compared with other resins, and are used for reducing the pigment ratio of the paint.
Further, the mica powder is sheet-structure mica powder; the sheet structure of mica powder can improve the leakproofness of coating, further seals the water route passageway in the coating, reduces steam infiltration route, improves the boiling water resistance ability. The mica powder flakes are oriented parallel to the paint film to form an inert, solid and flexible protective layer that is resistant to corrosion and solar radiation. Meanwhile, after the mica powder sheet seals the pores of the paint film, the internal stress uniformity of the coating is improved, so that the cracking resistance of the paint film is enhanced, which is shown in excellent adhesive force.
Furthermore, the non-floating aluminum paste is 5-60 um and is composed of a very smooth and extremely thin flaky structure, can be mixed with a flaky mica powder structure according to the mass ratio of 1: 1-5, and is uniformly dispersed in a blending resin formed by chlorinated polypropylene resin and coumarone resin to play a role of a rigid skeleton, so that the ring stiffness of the coating is improved, the conductive insulation and the flame retardance are improved, the mechanical properties such as the tensile strength and the bending strength of the coating are improved, and the boiling resistance of the coating is also improved. The relatively floating silver paste can be directionally arranged parallel to a paint film like mica powder, has the effect of sealing the paint film, is not oriented on the surface of the paint film to influence the adhesive force between layers, has the synergistic effect on the sealing effect of the paint film when matched with the mica powder, and has better water resistance than the single use. Is a commercial product, such as non-floating aluminum paste of Shandong silver arrow ZLG-101.
Further, the inorganic pigment titanium dioxide and the conductive carbon black are used for improving the covering power of a paint film.
Further, the solvent is any one or more of xylene, toluene, trimethylbenzene, butanone, acetone, cyclohexanone and methyl isobutyl ketone.
The preparation method of the chlorinated polypropylene coating is characterized by comprising the following steps:
(1) adding the organic bentonite into a solvent under the stirring state, adjusting the rotating speed according to the stirring state, adding absolute ethyl alcohol when the organic bentonite is in a uniform state and has no hard blocks, and stirring uniformly to prepare an organic bentonite paste;
(2) adding a solvent with the same mass into the non-floating aluminum paste for soaking for at least 1 hour;
(3) adding chlorinated polypropylene resin, coumarone resin, a dispersing agent, a defoaming agent, an inorganic pigment, a leveling agent and mica powder in a formula ratio into a stirring kettle, adding a solvent for adjusting viscosity, stirring uniformly at 1000r/min for 500 times without hard blocks, adding the organic bentonite paste prefabricated in the step (1), grinding by using a grinder until the fineness is below 25um, adding the aluminum paste obtained in the step (2), stirring uniformly, adjusting the viscosity, and filtering to obtain a coating product.
Further, the mass ratio of the solvent used in the step (1) to the organic bentonite is 1-3: 1;
further, the viscosity of the coating product obtained in the step (3) is 30-60s, and the measuring condition is to coat a No. 4 cup; the filtration is performed using 120 mesh silk.
Compared with the prior art, the invention has the following beneficial effects:
1. the coumarone resin and the chlorinated polypropylene resin are mixed and blended, and the coumarone resin has good performance, most of the resins are acrylic modified resins, the glass transition temperature of the resins is higher, the resins are generally mixed and used with the chlorinated polypropylene, and the miscibility is poor.
