Description
Technical Field
The invention relates to the field of coatings, in particular to a crystal color floor decorative coating and a preparation method thereof.
Background
The floor coating is a common material in the building industry and is applied to decorating ground to form a floor coating. With the development of modern industrial technology and production, the living standard of people is continuously improved, the requirements on working and living environments are higher and higher, the corrosion resistance, cleanness and wear resistance of the terrace are required, the dust content of indoor air is low, the terrace decoration is required to have remarkable personality, strong decoration and rich aesthetic feeling.
The epoxy resin floor material has the performances of water resistance, chemical corrosion resistance, acid resistance, alkali resistance, oil stain resistance, compression resistance, wear resistance, good adhesion and the like, has mechanical strength far higher than that of a concrete substrate, has enough protection effect on the floor, has low shrinkage of a paint film after construction and curing, can be coated into a thick film at one time, has the characteristics of good self-leveling property, attractive appearance, good decoration and the like, and is the floor coating material with the mature technology and the largest market share at present. Because the solvent is not contained, the environment is not polluted, and the dangers of combustion, explosion and the like do not exist, so that the solvent is widely applied to modern industrial terraces and meets various requirements. However, the existing epoxy resin terrace coating has the defects of monotonous color, single style, poor decorative performance and the like, and is difficult to meet the decorative requirement of commercial and civil building floors. Although the existing products try to add organic or inorganic toner, such as titanium dioxide, lemon yellow, phthalocyanine blue and the like, into the paint, and mix the required colors by composite use, the finally obtained products are still not strong enough in decoration, have no stereoscopic impression and are lack of visual effect. The Chinese patent application with publication number CN 106147537A, "an environmental protection color nanometer epoxy floor paint" comprises the following raw materials: the paint comprises water-based epoxy resin, diethylene glycol butyl ether acetate, polyvinyl acetate emulsion, polypropylene fiber, pigment, vinyl trimethoxy silane, hydroxyethyl cellulose, fatty alcohol-polyoxyethylene ether, butyl titanate, dioctyl sodium sulfosuccinate, sodium borate, nano manganese dioxide and dodecyl alcohol ester. The paint film formed by the color nano epoxy floor paint has smooth surface, hardness, wear resistance, pressure resistance, impact resistance and good corrosion resistance, but the pigment has single tone, no stereoscopic impression and weak decoration.
Glitter powder, also called glitter powder, is a surface treatment material with unique effect, and can be divided into PET, PVC glitter powder, metallic glitter powder, glitter series glitter powder and laser series glitter powder. The high-flash property of the decoration makes the decoration bright and attractive and adds more gloss. However, the material and shape of the glitter powder are different from those of common pigments, so that certain requirements are imposed on the formula and preparation of the coating, the use of the glitter powder is limited to a certain extent, and the traditional glitter powder-containing coating has relatively long curing time, so that the manufacturing efficiency is low.
Disclosure of Invention
The invention aims to provide a crystal color floor decorative coating which has strong decoration, aesthetic feeling, fast curing speed, good self-leveling property and mechanical property and good acid, alkali and salt resistance and a preparation method thereof aiming at the defects of the prior art.
The purpose of the invention is realized by the following technical scheme:
the crystal color floor decorative coating comprises the following preparation raw materials in percentage by weight:
preferably, the crystal color floor decorative coating comprises the following preparation raw materials in percentage by weight:
further, the orientation aid is tetrabutylammonium hydroxide.
Furthermore, the environment-friendly diluent is composed of allyl glycidyl ether and epoxy-terminated silicone oil in a weight ratio of 1: 0.01-0.05.
Preferably, the environment-friendly diluent is composed of allyl glycidyl ether and epoxy-terminated silicone oil in a weight ratio of 1: 0.02.
Further, the multicolor wafer is glitter powder, the glitter powder is made of PET, and the size range of the glitter powder is 10-50 mu m.
Further, the curing agent is modified alicyclic amine.
Further, the defoaming agent is any one of BYK a530 (bike a530), BYK 066N (bike 066N), EFKA2720 (ehf card 2720), EFKA 2022 (ehf card 2022), DEU CHEM 6800 (deli 6800), and TEGO 6800 (digao 6800).
Further, the leveling agent is any one of BYK320 (birk 320), BYK 354 (birk 354), EFKA 3030 (elvan 3030), EFKA 3600 (elvan 3600), and TEGO Glide B1484 (digogide B1484).
The invention provides a preparation method of a crystal color floor decorative coating, which is characterized in that a mixture prepared from E-51 epoxy resin, a defoaming agent, a leveling agent, an environment-friendly diluent, a colorful wafer and an orientation auxiliary agent is used as a color coating, and the prepared color coating is mixed with a curing agent before construction and use, and then the paint can be developed for construction, and specifically, the preparation method of the crystal color floor decorative coating comprises the following steps:
(1) adding E-51 epoxy resin into a dispersion mixer, starting stirring, sequentially adding an environment-friendly diluent, a defoaming agent, a leveling agent and a colorful wafer at the rotating speed of 400-500 r/min, and uniformly stirring to obtain a mixed solution;
(2) then adding the directional assistant into the mixed solution, and uniformly stirring at the rotating speed of 400-500 r/min to obtain colored paint;
(3) when in use, the curing agent is added into the colored paint and is uniformly mixed.
The curing agent in the invention is modified alicyclic amine, and the curing agent can be a commercial product and can also be prepared by the following method: the modified alicyclic amine curing agent is a polymer prepared by performing Mannich reaction on one or more cyclic diamines selected from alicyclic diamines (such as methylcyclopentadiene TAC), o-diamine methylcyclopentane (TDC) or isophorone diamine (IPDA), aldehyde compounds selected from acetaldehyde or salicylaldehyde and phenolic compounds selected from hydroquinone, resorcinol, cresol, bisphenol A or cardanol, and preferably the amine value range in the modified alicyclic amine curing agent is 300-340 mg KOH/g.
The invention adopts the colorful wafer to replace the inorganic and organic pigments used in the prior art, so that the prepared floor decorative coating has layering and stereoscopic impression, and the decoration of the floor coating is obviously improved. However, the multi-color chip is made of PET material and is slightly dissolved in ether environment-friendly diluent, so that the stability of the multi-color chip is reduced, and the decorative property of the coating is weakened. The inventor discovers through a large number of experiments that the addition of a certain amount of epoxy-terminated silicone oil into the reactive diluent can weaken the interaction between the colorful wafer and allyl glycidyl ether, improve the stability of the colorful wafer, and enable the appearance of the coating to be free from cracking and stripping after the decorative coating layer of the crystal colorful terrace is exposed to the sun and rain for 12 months in the outdoor environment, and the coating still has better glossiness, strong flashing effect, good flashing effect, concave-convex surface effect, layering, strong stereoscopic impression and lasting decorative effect. Meanwhile, the epoxy-terminated silicone oil has an epoxy functional group in a molecular structure, and can participate in a curing reaction to accelerate the curing process of the coating.
On the other hand, in order to improve the workability of the floor coating, promote the uniform distribution of the colorful wafers in the coating and improve the flashing effect, the inventor creatively adds a directional assistant in the formula, wherein the directional assistant is an oxygen-containing nucleophilic reagent tetrabutyl ammonium hydroxide, OH-and MeO-provided by the tetrabutyl ammonium hydroxide can generate nucleophilic reaction with carbonyl in the PET colorful wafer structure, so that the colorful wafers are firmly and uniformly distributed in the coating, the phenomenon that the colorful wafers float up to the surface layer of the coating due to low density is avoided, the construction effect is influenced, and the stereoscopic impression of the coating appearance is weakened. In addition, after the crystal color floor decorative coating containing the orientation auxiliary agent is dried, the stability of the colorful crystal plate in the coating layer is greatly improved, so that the decorative effect of the coating is durable.
Compared with the prior art, the invention has the following beneficial effects:
(1) the crystal color floor decorative coating provided by the invention has the advantages of rich colors, strong texture, rich levels and excellent decoration, can meet the requirements of modern high-grade places on floor coatings, has good construction property, high curing speed, good self-leveling property and mechanical property, has good tolerance to acid, alkali and salt, and can meet the requirements of different occasions.
(2) The crystal-color terrace decorative coating provided by the invention has moderate viscosity, a formed terrace paint film is flat and bright, hard and wear-resistant, pressure-resistant and impact-resistant, good in corrosion resistance, long in service life, extremely low in VOC content, and accords with the environmental protection concept, and the formed terrace paint film can play a role in protecting effects.
