Problems solved by technology

But so far, more than 95% of lignin is still directly discharged into rivers with "black liquor" or concentrated and burned, and is rarely used effectively. However, no matter whether lignin is directly discharged into rivers or concentrated and burned How to reduce the pollution of lignin to the environment and make it effectively used is a technical problem that the inventors have been eager to solve.

Embodiment 1 to 8

[0057] Embodiment 1 to 8 adopts following method to prepare artificial quartz stone:

[0058] At first, prepare cured resin, dissolve the PMMA of 25 parts by weight in the MMA monomer of 75 parts by weight, stir until dissolving; Then, according to the component proportioning that provides in the embodiment, add each component in the vacuum mixer, Stir and mix for 10-20 minutes under negative pressure with a vacuum degree of -0.05~-0.06MPa, then transfer the mixture to a vacuum press, and then make the vacuum degree reach -0.05~-0.06MPa, heat and vibrate under vacuum After 30 minutes of initial curing, keep the ambient temperature of the mold at 70-80°C during the process, then put the mold in an oven, and cure it at 130°C for 80 minutes; finally, take off Molding, thickness setting, polishing and cutting to make finished products.

Embodiment 9～10

[0060] According to the composition ratio given in the examples, add lignin powder, quartz sand, quartz powder, unsaturated resin, coupling agent, curing agent, accelerator, crosslinking agent, pigment, etc. into the mixer and stir and mix for 10 minutes , then transfer the mixture to a vacuum press, then evacuate to -0.09~-0.095Mpa, vibrate and compact under vacuum, press at room temperature for 10 minutes, then put it in an oven, raise the ambient temperature to 50°C for curing After 30 minutes, continue to raise the ambient temperature to 130°C, release the mold after curing for 80 minutes, and then cut to a thickness to obtain a finished product.

Abstract

A bio-based artificial quartz stone and a production process thereof are disclosed. The bio-based artificial quartz stone includes the following components by weight: 0-80% of quartz sand; 10-70% of quartz powder; 3-20% of curable resin; 0.05-3% of a curing agent; 0.01-40% of lignin; 0-5% of a crosslinking agent; 0.05-5% of a coupling agent; 0-1% of a promoter; 0-2% of a pigment; and 0-3% of a defoaming agent. According to the invention, the lignin is used in the artificial quartz, the environmental pollution of the lignin is reduced, the cost of the artificial quartz is reduced, and at the same time the weather resistance and light stability of the artificial quartz are improved, thus the artificial quartz has antibacterial ability, is green and environmental-friendly, and is suitable for using in building decoration of living environments.

Description

technical field [0001] The invention relates to an artificial quartz stone and its production process. Background technique [0002] Artificial quartz stone is a synthetic stone manufactured by artificial methods. The main components of artificial quartz stone are generally quartz sand or quartz powder, unsaturated resin, accelerator, coupling agent and curing agent, and appropriate amount of color paste, etc. Among them, the unsaturated resin is used as a binder, and under the action of curing agent and accelerator, it is combined with the filler to form a dense quartz stone after hardening. By adding different color pastes, different patterns of quartz stone can be produced. Due to the excellent physical and chemical properties of quartz sand and quartz powder, artificial quartz stone has excellent properties such as strong acid resistance, corrosion resistance, wear resistance, high temperature resistance, compression resistance, flexural resistance, and penetration resis...
