Description

A kind of artificial stone release materials and application process thereof
Technical field
The invention belongs to release materials technical field, particularly a kind of artificial stone release materials and application process thereof.
Background technology
Artificial stone is after being mixed with adhesive by the aggregates such as calcium carbonate, aluminium oxide, silica, inserts in the mould of steel, the material such as wooden, through a kind of construction material of vacuum press or vacuum pressed vibration moulding Post RDBMS.General employing the isolation artificial stone material such as die surface pad brown paper, kraft liner and die surface contact and reach the object of the demoulding.Also have and prevent artificial stone material cohering at die surface at die surface coating oil-based release agent.With brown paper, kraft liner as release materials, when vacuum press, vacuum pressed vibration moulding, brown paper or the easy gauffer of kraft liner cause stone surface uneven or embed stone surface, significantly improve stone surface resection (polishing amount).Oil-based release agent stripping result is unstable, and volatile organic content is high, and expensive.
Summary of the invention
The object of this invention is to provide a kind of artificial stone release materials, be coated in the die surface that artificial stone forming uses, anti-Adhesive Coating is formed after drying, solidification, this coating effectively can isolate the contact of artificial stone raw materials and steel die, prevent artificial stone raw materials from cohering at die surface, meanwhile, due to the self lubricity of release materials, make shaping after artificial stone easily easily can be separated from mould.
Another object of the present invention is to provide the application process of above-mentioned artificial stone release materials.
A kind of artificial stone release materials, is characterized in that: containing, for example the raw material of lower percent by weight in this release materials:
Preferably, the raw material summation in described artificial stone release materials is in 100wt%, and layered di-hydroxyl composite metal oxidate (LDHs) is 15.0wt%-25.0wt%.If the content of LDHs is lower than 10.0wt%, the anti-of formation coheres coating surface poor lubricity, affects demoulding effect; If its content is higher than 35.0wt%, anti-Adhesive Coating solidifies at normal temperatures, film forming difficulty.
The particle diameter of described LDHs is less than 10 μm, is preferably 0.6-2 μm.If its particle diameter is greater than 10 μm, the apparent pore (pin hole) of anti-Adhesive Coating increases, and the solvent composition (organic solvent) of artificial synthesis stone material easily infiltrates, and affects demoulding effect.
Preferred further, layered di-hydroxyl composite metal oxidate is magnalium carbonate form hydrotalcite [Mg 6al 2(OH) 164H 2o].
Preferably, the raw material summation in described artificial stone release materials is in 100wt%, and the content of magnesium silicate is 17.0-25.0wt%.The content of magnesium silicate is lower than 17.0wt%, and the wearability of anti-Adhesive Coating reduces; If its content is higher than 25.0wt%, anti-Adhesive Coating is frangible, easily comes off.

With hairbrush, the release materials of preparation in above-described embodiment 1-embodiment 9 is coated in above-mentioned steel plate sample and artificial stone specimen surface respectively.Dry 4 hours after first time coating, then apply the second layer, then dry more than 4 hours, anti-Adhesive Coating is able to drying, sclerosis.Prevent that cohering coating layer thickness is 150-180 μm.To the parallel preparation of the release materials of each embodiment 3 samples.
The evaluation of adhesive force:
The lattice device of drawing being spaced apart 3mm with blade marks 6 lines of cut on the surface of above-mentioned anti-Adhesive Coating, then line of cut square crossing in 90 ° marks 6 parallel lines of cut formation grids therewith.
Sweep several times before and after each line of cut of grid with hairbrush, and dust is purged clean with hair-dryer.
Cut that width is 24mm, the adhesive force test tape of length 40mm is placed on above above-mentioned grid and flattens.Adhesive tape one end length exceedes grid 20mm, and unsettled.
Arrest the unsettled one end of adhesive tape, and to cohere coating surface become the angle of 60 ° to be torn off by adhesive tape reposefully with anti-, then observe the phenomenon of coating shedding with the magnifying glass that multiplication factor is 3 times, the coating shedding area in stroke lattice region is evaluated.
Evaluation result is listed in shown in table 1.
The anti-Adhesive Coating of table 1 is in steel plate and artificial stone adhesive force evaluation result on the surface.
As can be seen from Table 1, the adhesive force on anti-Adhesive Coating and steel die surface that this release materials is formed is much better than expects surperficial adhesive force with artificial stone's famine, illustrate that this release materials completely can as release materials, and stripping result is good.The anti-Adhesive Coating that release materials in embodiment 1-6 is formed is higher than the adhesive force of embodiment 7-9 with the adhesive force on steel die surface, but with artificial stone's famine, the anti-Adhesive Coating that the release materials in embodiment 1-6 is formed expects that the adhesive force on surface is lower than the adhesive force of embodiment 7-9, illustrate that the stripping result of the release materials in embodiment 1-6 is more excellent.
The above is preferred embodiment of the present invention, but the present invention should not be confined to the content disclosed in this embodiment.The equivalence completed under not departing from spirit disclosed in this invention so every or amendment, all fall into the scope of protection of the invention.
