Problems solved by technology

[0003] Because the traditional unsaturated polyester resin used as a binder has the defects of low thermal transition point and large expansion coefficient, the block formed by adding this binder will not be damaged after pressing, curing and opening. The saturated polyester resin is still not fully reacted in the artificial stone, which makes the resin contained in the artificial stone block unstable, and some blocks also crack; Stone slabs are easy to deform, and the floor will warp and deform to varying degrees during the paving process and after paving

preparation example Construction

[0038] The preparation method of the aforesaid artificial stone blocks added with modifying agent comprises the steps:

[0039] Stir the unsaturated polyester resin as the binder with the curing agent system and then mix it with the stone, and then put the obtained artificial stone mud into the mold for molding, and the artificial stone mud is mixed with alkaline earth metal oxides and / or alkaline earth metal hydroxides.

[0040] Specifically include the following steps:

[0041] 1) stirring the unsaturated polyester resin and curing agent system;

[0042] 2) Stirring of graded filler stone powder;

[0043] 3) mixing and stirring the materials obtained in step 1) and step 2) respectively to form artificial stone mud;

[0044] 4) the artificial stone mud cloth cloth that step 3) obtains is in the mould;

[0045] 5) The artificial stone mud is vacuum-vibrated and pressed in the mold to form artificial stone blocks;

[0046] Wherein, there are two ways to add the modifying age...

Embodiment 1

[0052] The post-treatment process of artificial stone block in the present embodiment comprises the following steps:

[0053] 1. Vibrating and pressing artificial stone blocks under vacuum conditions;

[0054] 2. The pressed artificial stone blocks are soaked in a soaking pool with hot water for heating and curing;

[0055] Specifically: soak the artificial stone blocks in hot water for 3 hours, and the temperature of the hot water is 99°C;

[0056] After soaking, recycle the warm water overflowing from the soaking tank, heat it to a predetermined temperature, and then send it back to the soaking tank for recycling;

[0057] 3. Remaining at room temperature;

[0058] Continue to maintain the artificial stone blocks after heating and curing at room temperature, that is, stand at room temperature for 15 days;

[0059] 4. Then the artificial stone blocks are stripped. After the stripping, the artificial stone blocks are cut (opened), polished, sorted and packaged by a gang saw...

Embodiment 2

[0062] The post-treatment process of artificial stone block in the present embodiment comprises the following steps:

[0063] 1. Vibrating and pressing artificial stone blocks under vacuum conditions;

[0064] 2. The pressed artificial stone blocks are placed in a soaking pool with hot water, and heated and solidified by soaking in hot water;

[0065] Specifically: soak the artificial stone blocks in hot water for 15 hours, and the temperature of the hot water is 90°C;

[0066] After soaking, recycle the warm water overflowing from the soaking tank, heat it to a predetermined temperature, and then recycle it into the soaking tank for recycling;

[0067] 3. Remaining at room temperature;

[0068] Continue to maintain the artificial stone blocks after heating and curing at room temperature, that is, stand at room temperature for 8 days;

[0069] 4. Then remove the film of the artificial stone block, and after the film is removed, the block is cut (opened), polished and polish...

Abstract

The invention discloses a post treatment process of man-made stone raw materials. After pressing and before cutting, the man-made stone raw materials are subjected to soaking and curing treatment by liquid media with the temperature higher than the normal temperature; and then, normal-temperature maintenance is performed. The post treatment process has the advantages that the pressed man-made stone raw materials are subjected to maintenance post treatment, so that the traditional normal-temperature maintenance node is changed; the mode of firstly performing soaking, heating and curing treatment by liquid media with the temperature higher than the normal temperature and then performing normal-temperature maintenance is used; by using the post treatment process of soaking, heating and curing, unsaturated polyester resin reaction can be sufficient; and the stable product performance is achieved on the original basis, so that the quality problems of internal cracking, easy product deformation, warping and the like of the man-made stone raw materials are reduced.

Description

technical field [0001] The invention relates to the technical field of artificial stone, in particular to a post-treatment process for artificial stone blocks. Background technique [0002] In the prior art, there are two types of resin binder artificial stone products on the market, with quartz stone powder and marble powder as the main filler respectively. The former is called quartz stone, and the latter is called granite; There are also products in which these two main fillers are properly blended with each other. In most cases, quartz sand with a filler weight of 10% to 20% is added to the granite variety. No matter which type of artificial stone is mentioned above, the binder that binds the filler into an integral structure is unsaturated polyester resin. [0003] Because the traditional unsaturated polyester resin used as a binder has the defects of low thermal transition point and large expansion coefficient, the block formed by adding this binder will not be damage...
