Abstract
The invention discloses a method for preparing a wear-resistant reflective coating. The method includes: preparing a hydroxide sol; dissolving tetraethoxysilane into ethanol, then dropwise adding water, and dropwise adding hydroxide sol to obtain a second sol; preparing a TiO2 sol; stirring the second sol, and dropwise adding a fifth sol and water in the process of stirring to obtain a sixth sol; heating paraffin containing Span 40 in a water bath, dropwise adding the sixth sol into paraffin oil, stirring and filtering to obtain gel particles; sintering the gel particles to obtain reflective glass beads; washing the reflective glass beads, dipping and firing to obtain modified glass beads; adding water-soluble acrylic resin, waterborne polyurethane resin and waterborne alkyd resin into the water, mixing well, adding the modified glass beads, calcined kaolin, diatomite, fumed silica and a silane coupling agent, and evenly mixing; and then adding zinc borate, nano magnesium hydroxide, a toughening agent, an antifoaming agent, an anti-mildew agent and a pigment, and stirring evenly to obtain the wear-resistant reflective coating.
Description
Technical field
The present invention relates to reflective coating technical field, particularly relate to a kind of preparation method of wear-resisting light reflecting coating.
Background technology
Main raw material(s) that light reflecting material uses comprises resin, pigment, glass microballon etc., and any the same starting material are all vital to the performance impact of light-reflecting product.Wherein, adhering resin must have good workability, splendid cementability, if surface does not have the product of protective layer, also require water-repellancy, washing fastness to adhering resin, top layer resin requires good transparency, desirable specific refractory power, excellent weathering resistance and stability, connecing of each layer resin also must have good compatibility, could meet the optical characteristics requirement of light reflecting material product like this, service requirements and manufacture process requirement; For pigment, then require high transparent, form and aspect stability, the consistency good with resin, for glass microballon, then require to there is high refractive index, high transparent, low devitrification rate, good circularity, good granularity consistence and dispersiveness.Existing reflective coating often wear-resisting voltinism can be not ideal enough.
Summary of the invention
Based on background technology exist technical problem, the present invention proposes a kind of preparation method of wear-resisting light reflecting coating, gained coating reflecting effect be good, wear-resisting, corrosion resistance nature and ageing-resistant performance outstanding.
The preparation method of a kind of wear-resisting light reflecting coating that the present invention proposes, comprises the steps:
A, by zirconium nitrate, magnesium nitrate, cerous nitrate and nitrocalcite mix after, be added to the water dissolving and obtain mixing solutions, then sodium hydroxide solution is dripped, filter, filter cake cleaning is placed in water and carries out ultrasonic disperse, then heating in water bath, drips nitric acid to pH=3 ~ 4, obtains the first colloidal sol in heating in water bath process;
B, tetraethoxy added in ethanol and dissolves, then drip water, then adjust ph to 3 ~ 4, then drip the first colloidal sol, stir 45 ~ 60min and obtain the second colloidal sol;
C, add after methyl aceto acetate stirs in ethanol, then add tetrabutyl titanate and once stir and obtain the 3rd colloidal sol; In ethanol, add Jing Ti/Bao Pian COBALT NITRATE CRYSTALS/FLAKES, chromium nitrate and boric acid mix evenly and obtain the 4th solution; 4th solution is added dropwise in the 3rd colloidal sol, then carries out secondary stirring, then add water, then triple mixing, leave standstill and obtain the 5th colloidal sol;
D, the second colloidal sol to be stirred, in whipping process, drip the 5th colloidal sol and water obtains the 6th colloidal sol; Paraffin oil containing span 40 is carried out heating in water bath, and then drip the 6th colloidal sol and enter paraffin oil, then stir, filter, drying obtains gel particle;
E, sintered by gel particle, cooling obtains reflective glass beads;
F, reflective glass beads is placed in dehydrated alcohol soaks, then carry out ultrasonic cleaning, after vacuum-drying, the mixing solutions be placed in containing ruthenium ion floods, and then heats up, insulation, filters, and washing is dry, fires and obtains modified glass microspheres;
G, water-borne acrylic resin, waterborne polyurethane resin, aqueous alkide resin be added to the water mix after, add modified glass microspheres again, after calcined kaolin, diatomite, gas-phase silica, silane coupling agent mix, then add zinc borate, nano-sized magnesium hydroxide, toughner, defoamer, mould inhibitor, pigment stirs and obtain wear-resisting light reflecting coating.
