Further technical scheme is, also comprises 1 ~ 5 weight part antiseeping waterproofing agent.Need to have water-proof function for home bathroom articles for use, add antiseeping waterproofing agent, ensure home bathroom articles for use good waterproof performance, liquid product there will not be race to leak.Preferably, 2 ~ 4 parts of antiseeping waterproofing agents are also comprised.Best, 3 parts of antiseeping waterproofing agents are also comprised.
Further, 1 ~ 5 weight part tinting material is also comprised; A kind of in described tinting material optional autoxidation iron oxide black, red iron oxide, iron oxide yellow and iron oxide blue or the wherein mixture of at least two kinds.Suitable consumption is selected to mix the color of requirement depending on specific product requirement.
The preparation method of aluminosulfate cement composition of the present invention, is completed by following steps:
Take each raw material respectively by the weight part of raw material each in aluminosulfate cement composition, then get 50 parts of quartz sands and add in agitator, then add each additive, stir; Add sulphoaluminate cement base material again, continue to stir, in whipping process, add the quartz sand of surplus, stir, complete the preparation of aluminosulfate cement composition; Wherein, described each additive is other the raw material except quartz sand and sulphoaluminate cement base material.Such as, described each additive is staple fibre, sawdust, nano silicon, water-holding agent, cement quick dry agent and high-molecular cement water reducer; Or described each additive is staple fibre, sawdust, nano silicon, water-holding agent, cement quick dry agent, high-molecular cement water reducer and antiseeping waterproofing agent; Or described each additive is staple fibre, sawdust, nano silicon, water-holding agent, cement quick dry agent, high-molecular cement water reducer, antiseeping waterproofing agent and tinting material.
Aluminosulfate cement composition of the present invention is for making the application of household artwork or bathroom external member.
Adopt the making method of the application of aluminosulfate cement composition of the present invention making household artwork or bathroom external member as follows:
Step one, in aluminosulfate cement composition, add water, stir, vacuumize, obtain concrete material; Wherein, the add-on of described water is 20% ~ 30% of aluminosulfate cement composition weight;
Step 2, by the concrete material of step one inject mould, in shot process, keep mould be in vibrational state; After material feeding completes, left standstill by mould, form removal after 1.5 ~ 3 hours, obtains first product; Wherein, described mould adopts silicone mould.
Step 3, the first product of step 2 is placed in after water soaks and takes out, carry out maintenance, then surface treatment is carried out to the first product after maintenance, obtain finished product.
Further, in step one, described water is 25% ~ 30% of the weight of aluminosulfate cement composition.Not being both of consumption of water changes for weather, and winter gets minority, gets large number summer.
Further, in step 2, the material of described silicone mould is the silicone with alkali-resistivity additive, and shore hardness is at 26 ~ 28 degree.Wherein hardness is shore hardness standard A, reduces anti-interpolation of to burn till point, pulling force is strengthened.
Further, in step one, before carrying out vacuum pumping, add concrete defoamer in concrete material, the add-on of described concrete defoamer is 0.05% ~ 0.2% of aluminosulfate cement composition weight in step one.When temperature is low in the winter time, before vacuum operating, add defoamer, with the discharge of air in accelerate concrete material, avoid finished surface outward appearance to occur bubble.
Further, the concrete operations of maintenance described in step 3 are as follows: first product be placed in water soak after take out, use film paper environmental sealing, leave standstill maintenance, after 10 ~ 18 days, carry out at the bottom of mill successively to first product, sanding process; Then continue maintenance, obtain finished product; In maintenance processes, when hickie appears in first product surface, the industrial cleaning agent after acetic acid or dilution is adopted to clean.
Further, in step 3, carrying out surface-treated concrete operations to the first product after maintenance is: the surface of the first product after maintenance is sprayed water-based gloss oil or adopt the wiping of wax water, obtain ganoid finished product.The excellent adsorption of water-based gloss oil and completed matrix, water-repellancy is good.
Further, in step 3, carrying out surface-treated concrete operations to the first product after maintenance is: be immersed in hydrochloric acid by the first product after maintenance, is dissolved away by the sulphoaluminate cement base material on surface, obtains the finished product with coarse effect.
Aluminosulfate cement composition provided by the invention, by consumption proportion between each raw material, and each raw material interphase interaction, can snap cure, and reduce shaping breakage rate.The staple fibre (such as, staple glass fibre) added enhances the obvolvent degree of ettringite, and product structure power is strengthened.Sawdust has the function of moisturizing and enhancing, heat release in reaction, and moisture evaporation is too fast, and reaction can be made incomplete, and sawdust can pin portion of water, and reaction can be continued, thus product structure power is strengthened, and sawdust has the function of anti-folding and anti-pressing simultaneously.Adding of nano silicon, as nano level nano silicon, the hydroxyl in base-material is increased, sufficient reacting, multiple improves structural capacity.High-molecular cement water reducer, improve the diffusion uniformity of cement base-material in water, concrete aquation cement composition being added water obtain is even, structural capacity is strengthened, reduce the object that water consumption also reaches early strong, the intermolecular cohesive force of cement and water resistance can be improved, serve the effect improving mortar mobility and enhancing simultaneously, solve the problem of the perfusion difficulty to artworks such as the thinner bathrooms of wall thickness.Cement quick dry agent is for regulating final setting time.
Aluminosulfate cement composition of the present invention is for making the application of household artwork or bathroom external member, vacuum pumping is utilized to ensure bubble-free in concrete material, mold vibration in shot process, the silicone mould adopted, and effective maintenance process, make and obtain household artwork or bathroom external member finished product.The finished product that making obtains is without internal injury, and structural capacity is strong, smooth surface, and white mist is even, and intensity can be crossed 60cm and fall case.Manufacture craft is efficient, cost is low, and qualification rate reaches 99%.
