Problems solved by technology

The former is easy to make, economical and practical, and saves resources, but its monotonous color and rough appearance can no longer satisfy people's desire for luxury and beauty.
Although the latter is beautiful and popular among users, there are many unfavorable factors such as shortage of natural stone resources, difficulty in processing, and high cost. The scarcity of natural stone and rising prices have prompted people to continue to explore and innovate

preparation example Construction

[0039] The preparation method of the above-mentioned artificial stone protection box comprises the following steps:

[0040] Step 1, prepare spirocyclic orthoester;

[0041] Step 2: Mix the modified unsaturated polyester resin, spirocyclic orthoester, mold release agent, coupling agent, and color paste to obtain component A, and mix part of granite powder or quartz powder with glycerol ether, polymethacrylic acid The methyl ester-styrene or polyvinyl acetate-styrene is mixed to obtain the B component, and the A component, the B component and the initiator are mixed and stirred to obtain a uniformly mixed slurry;

[0042] Step 3, adding the slurry obtained in step 2, short glass fibers and remaining granite powder or quartz powder and initiator, and continue stirring to obtain a viscous semi-solid intermediate;

[0043] Step 4: Preheating the protective box mold, placing the obtained semi-solid intermediate into the mold, liquefying the intermediate and filling the mold cavity...

Embodiment 1

[0046] Preparation of spirocyclic orthoester: 10kg γ-butyrolactone (120mol) was first diluted with 8L carbon tetrachloride, and 200mL boron trifluoride etherate (1.6mol) was added dropwise at a low temperature of -25 degrees, followed by stirring. Slowly add 6kg (60mol) 1,2-epoxy cyclohexane dropwise down, the temperature of reaction solution is controlled below 45 degrees, in reaction solution, add 1.1L (8mol) triethylamine quenching reaction, then use saturated carbonic acid The reaction solution was washed with sodium hydrogen and deionized water, dried over anhydrous sodium sulfate, then evaporated to dry the organic solvent, and distilled under reduced pressure to obtain 4.13 kg of colorless liquid spiro orthoester for subsequent use.

[0047] Mix 15 parts of polyurethane unsaturated polyester resin, 1.32 parts of the above-mentioned spirocyclic orthoester, 0.75 part of zinc stearate, 0.1 part of coupling agent SCA-R74M and an appropriate amount of color paste to obtain co...

Embodiment 2

[0051] Preparation of spirocyclic orthoester: 8Kg γ-butyrolactone (90mol) was first diluted with 120L carbon tetrachloride, at -25 degree low temperature, 200mL boron trifluoride etherate (1.6mol) was added dropwise, then slowly dripping Add 4kg (30mol) styrene oxide, complete dropwise addition in about 4 hours, dropwise add 40% aqueous sodium hydroxide solution in the reaction solution, filter to obtain the organic phase of the thick product, wash the organic phase 3 times, dry over anhydrous sodium sulfate , then evaporated the organic solvent, and distilled under reduced pressure to obtain 2.35kg of colorless liquid spirocyclic orthoester for subsequent use.

[0052] Mix 15 parts of polyurethane unsaturated polyester resin, 1.32 parts of spirocyclic orthoester, 0.75 part of mold release agent zinc stearate, 0.1 part of coupling agent SCA-R74M and an appropriate amount of color paste to obtain component A. To obtain B components. Component A, component B, 0.25 part of init...

Abstract

The artificial stone protective box of the present invention and the preparation method thereof belong to the technical field of artificial stone, and the composite low shrinkage agent in the raw material of the protective box adopts polymethyl methacrylate-styrene copolymer and spirocyclic orthoester-glycerol ether copolymer Compounding or compounding of polyvinyl acetate-styrene copolymer and spiro orthoester-glyceryl ether copolymer. The compound use of spirocyclic orthoester, glycerol ether and polymethyl methacrylate-styrene copolymer in the low shrinkage additive not only retains the advantages of good gloss of the product, but also makes the volume and mechanical properties of the product more stable. In addition, the unsaturated polyester resin in the raw material of the protective box adopts polyurethane modified unsaturated polyester resin. Since the unsaturated polyester resin has a rigid straight chain structure, the use of polyurethane modified unsaturated polyester resin can make the chain contain soft chains. segment and hard segment, so that the polyurethane modified unsaturated polyester resin has better flexibility, thus ensuring the impact resistance of the artificial stone protective box.

Description

technical field [0001] The invention relates to the technical field of artificial stone, in particular to an artificial stone protection box and a preparation method thereof. Background technique [0002] At present, in the funeral industry, the public takes the urns buried in the earth for safety, and the sarcophagus needs to be sealed again for protection. There are currently two types of sarcophagi; one is an artificial sarcophagus made of cement, and the other is a sarcophagus made of natural stone. The former is easy to make, economical and practical, and saves resources, but its monotonous color and rough appearance can no longer satisfy people's desire for luxury and beauty. Although the latter is beautiful and beautiful, it is deeply loved by users, but there are many unfavorable factors such as shortage of natural stone resources, difficult processing, and high cost. The scarcity of natural stone and rising prices have prompted people to continue to explore and in...
