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 stones;

[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 agent in...

Embodiment 1

[0052] The artificial stone blocks maintenance process 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 placed in the spray area for heating and curing;

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

[0056] After spraying, recycle the warm water overflowing from the reservoir, heat it to a predetermined temperature, and then spray it into the block mold 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.

Abstract

The present invention discloses an artificial stone rough block curing process, which artificial stone rough block is subjected to spraying curing treatment by using a liquid medium with a temperature of higher than a normal temperature after pressing and before cutting, and then normal temperature curing is performed. According to the present invention, the pressed artificial stone rough block is cured, the traditional normal temperature curing way is changed, the way sequentially comprising heating curing through the spraying of the liquid medium with the temperature of higher than the normal temperature and the normal temperature curing is used, and through the spraying heating curing process, the reaction of the unsaturated polyester resin can be complete, the relatively stable product performance can be achieved on the original basis, and the quality problems of internal cracking, easy product deformation generation, easy product warping generation and the like of the artificial stone rough block can be reduced.

Description

technical field [0001] The invention relates to the technical field of artificial stone, in particular to an artificial stone block maintenance process. 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 damaged after...
