Abstract

The invention relates to a high-luminosity anti-fouling artificial quartzite board and a manufacturing method. The board comprises the following raw materials, a particle raw material with the size of 0.075-5 mm, quartz powder with the size of 0.005-0.045 mm, colored pigment, a silane coupling agent, an unsaturated polyester resin, a curing agent, and a high-luminosity anti-fouling liquid. The manufactured artificial quartzite board has the surface gloss no less than 80 GS and is great in anti-fouling performance. The performance of the artificial quartzite board can be further improved, and the limit can be broken, so that the board can be further widely popularized.

Example Embodiment

[0027] The preferred embodiments of the present invention are described below. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] The high-gloss anti-fouling artificial quartz stone plate of the present invention includes the following raw materials: according to weight percentages, 0.075-5mm particles 60%, 0.005-0.045mm quartz powder 25%; colored pigments 2%; silane coupling agent 0.5% ; Unsaturated polyester resin 11.5%; curing agent 1%.

[0029] Among them, the high-gloss anti-fouling liquid is composed of organic silicon and fluorine compounds as the main components, and the particle raw materials are quartz particles or glass particles, or a mixture of the two.

[0030] Colored pigments are one or more of inorganic pigments or organic pigments or color pastes. Inorganic pigments are titanium white, medium chrome yellow, iron yellow, iron red or iron black, and organic pigments are scarlet powder, phthalocyanine green and phthalocyanine blue, The color pastes are white paste, black paste, red paste, phthalocyanine green paste, and phthalocyanine blue paste.

[0031] The unsaturated polyester resin may also be one or more of epoxy resin, phenol resin, acrylic resin and polyurethane resin.

[0032] The curing agent is a variety of (2-ethylhexanoic acid) tert-butyl peroxide, methyl ethyl ketone peroxide, tert-butyl peroxide benzoate, dibenzoyl peroxide and fatty polyamines.

[0033] The silane coupling agent is γ-methacryloxypropyltrimethoxysilane, γ-(2,3-glycidoxy)propyltrimethoxysilane, N-β(aminoethyl)-γ- Aminopropylmethyldimethoxysilane, N-(β-aminoethyl)-γ-aminopropyltriethoxysilane, N-β(aminoethyl)-γ-aminopropyltrimethoxysilane , Aniline methyl triethoxy silane, γ-aminopropyl triethoxy silane, vinyl triethoxy silane, vinyl trimethoxy silane and γ-chloropropyl triethoxy silane .

[0034] A preparation method of high-gloss anti-fouling artificial quartz stone plate includes the following steps:

[0035] (1) Weigh each component according to the formula;

[0036] (2) Stirring: Pre-mix the weighed quartz particles, glass particles and silane coupling agent in a double planetary mixing tank; pour the mixed curing agent, decorative colored pigments and unsaturated polyester resin into the double planet Mix in a mixing tank, and then add quartz powder for mixing. Stirring frequency 15~55Hz, stirring time 180~600s;

[0037] (3) Cloth: Send the mixed materials in step (2) to the disperser for further dispersing, after dispersing, enter the distributing machine by electronic metering;

[0038] (4) Pressing: After the cloth is finished, it is vibrated and pressed by pressing equipment under the vacuum condition of -0.1Mpa, the pressure is 50~200t, the vibration frequency is 30~55Hz, and the time is 60~600s;

[0039] (5) Thermal curing: After vibrating and pressing, enter the curing equipment and cure at a temperature of 80-130°C, and the curing time is 30-180 minutes;

[0040] (6) After the curing is completed, place it at room temperature and wait until it is completely cooled, then enter the plate thickness setting machine to set the thickness, and then polish it through the water mill polishing equipment;

[0041] (7) For the polished and deep-processed products, the surface should be treated with high gloss and antifouling, sprayed with high gloss antifouling liquid on the surface of the board, and wiped with a dust-free cloth to evenly complete the antifouling treatment;

[0042] (8) Wait for 3 to 5 minutes, spray the high-gloss anti-fouling liquid on the surface of the plate at a height of 20 cm from the plate at an angle of 45° until the surface forms a bright surface. Stop spraying and leave it for 24 to 48 hours, and finish the highlight treatment when the crystal surface solidifies.

[0043] (9) Test the gloss and antifouling performance of the artificial quartz stone plate prepared above, and the results are as follows:
