preparation example Construction

[0028] The invention provides a method for preparing foamed ceramics and a method for dry powder making thereof. Because the uniformity of the ceramic powder obtained by the dry powder making method is better, the foamed ceramics prepared by using the ceramic powder are improved. the quality of.

[0029] The principle that the dry powder making method can obtain ceramic powder with better uniformity will be described in detail below.

[0030] The concrete steps of dry powder making method are as follows:

[0031] S11. Weigh 1-5 parts by weight of mineralizer, 10-20 parts by weight of pore-forming material and 1-5 parts by weight of modifier, and mix mineralizer, pore-forming material and modifier Mix for 3-10 minutes at a temperature of 200-250° C. and a rotation speed of 800-3000 rpm to obtain a preliminary premix.

[0032] Among them, the mineralizer is mullite or dolomite. The particle morphology of the above-mentioned mineralizers is needle-like, and their own diffusion...

Embodiment 1

[0051] Each raw material is measured in parts by weight. The concrete steps of dry powder making method are as follows:

[0052]Weigh 1 part of mullite, 20 parts of calcium carbonate and 1 part of titanate coupling agent such as tetrabutyl titanate, and mix mullite, calcium carbonate and titanate coupling agent in a high-speed mixer , wherein the mixing temperature is 200° C., the mixing speed is 800 rpm, and the mixing time is 10 minutes to obtain a preliminary premix.

[0053] Weigh 0.5 part of clay and 0.5 part of attapulgite, and mix with the above-mentioned primary premix for 40 minutes at a speed of 8 rpm with the above-mentioned preliminary premix to obtain an intermediate premix.

[0054] Weigh 10 parts of nepheline, 5 parts of sodium potassium feldspar, and 70 parts of basalt powder, and mix with the above-mentioned intermediate premix in a horizontal coulter mixer for 30 minutes to obtain ceramic powder.

Embodiment 2

[0056] Each raw material is measured in parts by weight. The concrete steps of dry powder making method are as follows:

[0057] Weigh 5 parts of dolomite, 5 parts of calcium carbonate, 5 parts of calcium phosphate and 5 parts of silane coupling agent such as γ-glycidyl etheroxypropyl trimethoxysilane, and mix dolomite, calcium carbonate, calcium phosphate and silane coupling agent The joint agent is mixed in a high-speed mixer, wherein the mixing temperature is 250° C., the mixing speed is 3000 rpm, and the mixing time is 3 minutes to obtain a preliminary premix.

[0058] Weigh 2 parts of attapulgite and 3 parts of bauxite, and mix with the above-mentioned preliminary premix in a twin-screw conical mixer at a speed of 10 rpm for 20 minutes to obtain an intermediate premix.

[0059] Weigh 10 parts of potassium albite feldspar, 15 parts of spodumene powder and 80 parts of basalt powder, and mix with the above-mentioned intermediate premixed material with a paddle mixer for 45 ...

Abstract

The invention provides a preparation method of foamed ceramic and a dry-method powder preparation method therefor. The dry powder preparation method of the foamed ceramic comprises the following steps: weighing 1-5 parts by weight of a mineralizer, 10-20 parts by weight of a pore-forming material and 1-5 parts by weight of a modifier, and mixing the mineralizer, the pore-forming material and the modifier for 3-10 minutes at the temperature of 200-250 DEG C and the rotating speed of 800-3000 revolutions per minute to obtain a preliminary premix; weighing 1-5 parts by weight of an adhesive, and mixing the adhesive with the preliminary premix to obtain an intermediate premix; weighing 15-25 parts by weight of a fluxing agent and 70-80 parts by weight of mineral powder, and mixing the fluxing agent and the mineral powder with the intermediate premix to obtain the ceramic powder. The ceramic powder prepared through the dry-method powder preparation method is good in uniformity, the whole material mixing time is short, the time is saved, the material mixing efficiency is improved, and the economic benefits of enterprises are improved.

Description

technical field [0001] The invention relates to the technical field of ceramic production, in particular to a preparation method of foamed ceramics and a dry powder making method thereof. Background technique [0002] Foamed ceramics is a ceramic material with a closed pore structure inside. It has excellent properties such as light weight and high strength, fire and flame retardant, thermal insulation, waterproof and moisture-proof, sound insulation and noise reduction, etc. With the characteristics of recycling, it is a new type of green environmental protection material in the construction field. [0003] The production methods of foamed ceramics include wet pulverizing technology and dry pulverizing technology. Among them, the "three highs and one low" phenomenon of high energy consumption, high pollution, high input and low output value brought about by wet milling technology deviates from the energy saving and consumption reduction advocated by the state, while dry mi...
