The invention adopts the following method:
an antistatic soft porcelain decorative material is characterized in that: the anti-static soft porcelain decorative material comprises the raw materials of cement, quartz sand, a coupling agent, inorganic pigment, silicone-acrylic emulsion, aniline, an initiator, doping acid and water.
The initiator is ammonium persulfate or potassium persulfate;
the initiator is mainly peroxide, and the peroxide can oxidize aniline to promote aniline to produce polymerization reaction, so that polyaniline is obtained.
The doping acid is phytic acid.
The phytic acid is polyphosphoric acid, has flame retardant property, can improve the flame retardant property of the soft porcelain material as an additive of the soft porcelain material, and on the other hand, the phytic acid is used as doping acid, can be doped onto a molecular chain of polyaniline in the polymerization process of the polyaniline so that the conductivity of the polyaniline is enhanced.
The anti-static soft porcelain material comprises, by weight, 30-50 parts of cement, 30-50 parts of quartz sand, 2-5 parts of a coupling agent, 0-5 parts of an inorganic pigment, 30-50 parts of a silicone-acrylic emulsion, 10-15 parts of aniline, 1-4 parts of an initiator, 2-5 parts of a doping acid and 20-30 parts of water.
The dosage of the aniline, the initiator and the doping acid can influence the synthesis condition of the polyaniline, and the dosage of each substance defined by the invention can ensure that the particle size of the polyaniline synthesis is smaller and the reaction is mild.
The invention also provides a preparation method of the anti-static soft porcelain decorative material, which is characterized by comprising the following steps:
(1) preparing powder: mixing cement, quartz sand, a coupling agent and an inorganic pigment, and stirring to obtain uniform powder;
(2) polyaniline synthesis: adding phytic acid, aniline and an initiator into water, stirring at a high speed, and adding a silicone-acrylic emulsion after the reaction is finished to obtain a liquid material containing polyaniline;
(3) preparing a mixed material: adding the powder prepared in the step (1) into the liquid material obtained in the step (2), and uniformly stirring to obtain a mixed material;
(4) molding: and injecting the mixed material into a mold for compacting and molding, sending the mold into an oven, curing, molding, drying and demolding to obtain the anti-static soft porcelain decorative material.
The stirring in said step (1) is carried out in a kneader.
The stirring in the step (2) is high-speed stirring, and the rotation speed of the stirrer is 500-.
The reaction time in the step (2) is 0.5-2 hours.
Because the polymerization reaction of the polyaniline is an exothermic reaction and the polymerization speed is high, a large amount of aqueous medium is added into the polymerization environment, the concentration of the aniline and the initiator is relatively low due to the high water content, the polyaniline can be rapidly radiated under the condition of high-speed stirring during polymerization and can be slowly reacted, and all the factors enable the polyaniline to exist in a solution in a particle form, so that the polyaniline can be uniformly dispersed in a mixed material finally, and the conductivity of the soft porcelain decorative material can be effectively improved.
The curing conditions in the step (4) are temperature: 100-: 1-5 h.
The anti-static soft porcelain decorative material prepared by the invention has the advantages of less aniline raw material, low cost, uniform polyaniline dispersion in soft porcelain, excellent conductivity and excellent mechanical property; the preparation method of the anti-static soft porcelain material provided by the invention is simple in process and can be suitable for batch production.
