Embodiment 1

[0023] A method for manufacturing a stain-resistant artificial quartz stone, comprising the following steps:

[0024] (1) Evenly mix quartz sand and quartz stone powder, quartz sand: 2 mesh < particle size ≤ 4 mesh, 4 mesh < particle size ≤ 6 mesh, 6 mesh < particle size ≤ 8 mesh, 8 mesh < particle size ≤ 16 mesh, 16 mesh < Particle size ≤ 24 mesh, 24 mesh < particle size ≤ 40 mesh, 40 mesh < particle size ≤ 80 mesh and 80 mesh < particle size ≤ 120 mesh, these 8 particle gradations account for 10%, 10%, 10% of the total weight, 10%, 15%, 15%, 12%; quartz powder 400 mesh: 6%; accounting for 88% of the total mass.

[0025] (2) Vacuum vibration high-pressure molding: Add 2.3wt% of antifouling active factor (white cement 1.8wt% active factor powder additive 0.5wt%) and fully stir, then add 1.0wt% of water, and stir again, modified resin resin 8.7 Wt% (vinyl resin 8wt%, tetrafluoroethylene fluorosilicone resin 0.7wt%), after mixing evenly, use a press for high-pressure vibration ...

Embodiment 2

[0028] A method for manufacturing a stain-resistant artificial quartz stone, comprising the following steps:

[0029] (1) Evenly mix quartz sand and quartz powder, quartz sand: 2 mesh < particle size ≤ 4 mesh, 4 mesh < particle size ≤ 6 mesh, 6 mesh < particle size ≤ 8 mesh, 8 mesh < particle size ≤ 16 mesh, 16 mesh < Particle size ≤ 24 mesh, 24 mesh < particle size ≤ 40 mesh, 40 mesh < particle size ≤ 80 mesh and 80 mesh < particle size ≤ 120 mesh, these 8 kinds of particle gradation accounts for 12%, 13%, 15% of the total weight, 10%, 10%, 10%, 10%; quartz powder 400 mesh: 8.6%; accounting for 88.6% of the total mass.

[0030] (2) Vacuum vibration high-pressure forming: add antifouling active factor 1.8wt% (white cement 1.5wt% active factor powder additive 0.3wt%) and fully stir, after mixing evenly, add 0.6wt% water again, and stir again, then Add 9.0wt% modified resin resin (8wt% vinyl resin, 1wt% tetrafluoroethylene-based fluorosilicone resin), and use a press for high-p...

Abstract

The invention discloses a stain-resistant artificial stone plate and a preparation method thereof. The stain-resistant artificial stone plate provided by the invention is prepared by using a mixture of quartz sands with different particle sizes and quartz powder, resin, stain-resistant active factors and water as raw materials so as to prepare an artificial stone plate, and subjecting the obtained artificial stone plate to special treatment so as to form a micron-grade thin film which has hydrophobic and oleophobic characteristics and self-cleaning property and enables the stain-resistant property of the obtained stain-resistant artificial stone plate to be improved by 2 grades compared with the stain-resistant property of a convention artificial stone plate; thus, stains on the surface of the stain-resistant artificial stone plate in the invention can be cleaned without using of a cleaning agent in 15 days. The stain-resistant artificial stone plate provided by the invention has a normal service life of more than 20 years and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of processing cement, clay or stone, in particular to a stain-resistant artificial stone plate and a preparation method thereof. [0002] technical background [0003] Since the artificial quartz stone entered the Chinese market in 2005, it immediately attracted the attention of Chinese people and quickly occupied the market share of China's building materials; The emergence of high-quality, high-value-added artificial quartz stones allows products to go abroad. [0004] At present, artificial quartz stone is composed of quartz stone aggregate and quartz stone powder with a mass ratio of about 90%, and about 10% of other additive powders, such as pigments, resins, active factors, additives, etc. It is prepared through the processes of thorough mixing and stirring, vacuum and high-pressure vibration pressing, room temperature curing, thickness setting, grinding and polishing. The above-mentioned ordinary art...
