Problems solved by technology

But so far, more than 95% of lignin is still directly discharged into rivers or concentrated and burned as black liquor, and is rarely used effectively. However, whether lignin is directly discharged into rivers or concentrated and burned as "black liquor All produce environmental pollution, 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 1～4

[0058] First prepare PMMA resin, dissolve 25 parts by weight of PMMA in 75 parts by weight of MMA monomer, and stir until dissolved. Then according to the formula ratio batching of each material in embodiment 1~4 respectively, add PMMA resin, coupling agent, crosslinking agent, curing agent, lignin powder, inorganic filler and pigment in vacuum mixer, in vacuum tightness be-0.05 Stir and mix for 10-15 minutes at ~-0.06MPa, then transfer the mixed material to a vacuum press, vibrate and compact under vacuum (vacuum degree -0.05~-0.06MPa), transfer the compacted material into Curing in an oven, keep the curing temperature at 80°C during the initial curing process, after the initial curing for 40 minutes, then raise the temperature to 130°C and keep it for 80 minutes, so that the mixed material completes the post-curing process, and finally demoulding, thickness setting, polishing, Finished products are cut.

Embodiment 5～8

[0060] According to the formula ratio batching of each material in embodiment 5~8, first add unsaturated resin, crosslinking agent, coupling agent, curing agent and accelerator, lignin powder inorganic filler and pigment in mixer, stir and mix for 10 minutes, Then transfer the mixed material to a vacuum press, then evacuate it to -0.09~-0.095MPa, vibrate and compact it under vacuum, and then transfer it to an oven and keep it warm for 40 minutes at 50°C for preliminary curing , and then heat up to 130°C for post-curing, heat preservation for 80 minutes, demoulding, and finally thickness setting, polishing, and cutting to obtain finished products.

Embodiment 9～10

[0062] According to the formula ratio batching of each material in embodiment 9~10, first add unsaturated resin, crosslinking agent, coupling agent, curing agent and accelerator etc. in mixer, add lignin powder inorganic filler and pigment after stirring thoroughly, Stir and mix for 10 minutes, then pour the mixed material into shape, then evacuate it to -0.09~-0.095MPa, keep it at 50°C for 40 minutes for preliminary curing, then raise the temperature to 130°C for post-curing, and keep it warm for 90 Minutes later, the mold is demoulded, and finally the thickness is determined, polished, and cut to obtain the finished product.

Abstract

A biobased artificial stone and a production process thereof are disclosed. The artificial stone includes the following components: inorganic filler, resin, a curing agent, an accelerating agent, a crosslinking agent, a coupling agent, an antifoaming agent, lignin and a pigment. The formula of the artificial stone includes by weight: 10-85% of the inorganic filler; 3-60% of the resin; 0.03-3% of the curing agent; 0-2% of the accelerating agent; 0.05-2% of the coupling agent; 0.05-5% of the crosslinking agent; 0-3% of the antifoaming agent; 0.01-40% of the lignin; and 0-2% of the pigment. According to the invention, the lignin is used in the artificial stone, the lignin is turned into wealth from waste, the environmental pollution of the lignin is reduced, the cost of the artificial stone is reduced, and at the same time the weather resistance and light stability of the artificial stone are improved, thus the artificial stone has antibacterial ability, is green and environmental-friendly, and is suitable for building decoration of living environments.

Description

technical field [0001] The invention relates to an artificial stone and its production process. Background technique [0002] Artificial stone is a new type of composite material, which is made by mixing unsaturated polyester resin with fillers and pigments, adding a small amount of initiator, and going through certain processing procedures. Because of its non-toxic, non-radioactive, flame-retardant, non-stick oil, non-seepage, antibacterial and mildew-proof, wear-resistant, impact-resistant, easy maintenance, seamless splicing, arbitrary shape, low cost, resource reuse and decorative effects Good and other advantages are gradually becoming the new favorite in the decoration and building materials market. [0003] However, the artificial stone in the prior art also has its inherent disadvantages, such as poor light stability and weather resistance; most of the raw materials of the artificial stone are stone, and the manufacturing cost is relatively high. In addition, with ...
