Abstract

The invention particularly relates to a manufacture method for a staining resistant artificial quartz stone, which includes the steps of quartz stone powder sand surface modification, mixed pressing, sizing and solidifying and the like to generate a transparent film on the surface of the artificial quartz stone. The manufacture method has the advantages that by means of mechanical activation and modification of quartz stone powder sand serving as raw materials of the artificial quartz stone, flowability of the quartz stone powder sand during pressing is enhanced so that the quartz stone powder sand tends to be accumulated orderly and most densely, and binding of the quartz stone powder sand and resin during solidification is enhanced; the proportion and the grain distribution range are strictly controlled in an artificial quartz stone formula so that micron-sized pore quantity on the surface of the artificial quartz stone is decreased maximally; the surface of the artificial quartz stone is filled to form chemical adsorption so as to improve glossiness of the surface of the artificial quartz stone; and the micron-sized film formed on the surface of the artificial quartz stone has the hydrophobic feature, oil stains within 24 hours can be cleaned by wet cotton cloth, and hidden dirt and bleeding are effectively prevented, therefore, the artificial quartz stone is high in staining resistance. The manufacture method is simple in process, easy in operation and short in consumed time.

Description

[0001] technical field [0002] The invention relates to a method for manufacturing a stain-resistant artificial quartz stone, in particular to a method for manufacturing a stain-resistant artificial quartz stone. [0003] Background technique [0004] Artificial quartz stone (or diamond / diamond) originated in Spain. It was called Celite when it entered China in 2005. When artificial quartz stone was recognized by more and more consumers, in 2006, some people in China began to develop artificial quartz stone. Quartz stone, in 2007, many manufacturers have launched domestic artificial quartz stone. [0005] At present, artificial quartz stone is composed of about 90% natural quartz and about 10% additives such as colorants, resins and curing agents. It is formed by negative pressure vacuum, high-frequency vibration, heating and curing (the temperature depends on the type of curing agent); its texture is hard (Mohs hardness 5-7), and the structure is dense (density 2.3-2.5g / ...
