preparation example Construction

[0031] A second aspect of the present invention provides a method for preparing the described lightweight flexible soft porcelain, the method comprising:

[0032] (1) firstly mixing the base material, expanded graphite and polypropylene short fibers, and then adding silica sol, silane coupling agent and water for second mixing to obtain a mixture;

[0033] (2) Mix the foaming agent and the inorganic flame retardant for the third time, then introduce sodium carboxymethyl cellulose and water, and stir to obtain a foaming liquid;

[0034] (3) The mixture and the foaming liquid are mixed for the fourth time, and then left to stand for defoaming to form a paste. After injection molding, the second stand is performed, and then dehydrated.

[0035] In the present invention, in step (1), the conditions of the first mixing and the second mixing are not limited, as long as they can be fully mixed; for example, the mixing time is 20-60 min respectively.

[0036] According to the present...

Embodiment approach

[0041]According to a preferred embodiment of the present invention, the preparation method of the lightweight flexible soft porcelain comprises:

[0042] (1) firstly mixing the base material, expanded graphite and polypropylene short fibers, and then adding silica sol, silane coupling agent and water for second mixing to obtain a mixture;

[0043] With respect to the base material of 10 parts by weight, the consumption of the water is 70-100 parts by weight;

[0044] (2) The foaming agent and the inorganic flame retardant are mixed for a third time for 30-50 minutes, then sodium carboxymethyl cellulose and water are introduced, and the foaming liquid is obtained by stirring for 5-10 minutes;

[0045] With respect to 10 parts by weight of foaming agent and inorganic flame retardant, the amount of water used is 100-150 parts by weight;

[0046] (3) The mixture and the foaming liquid are subjected to the fourth mixing for 30-50min, the fourth mixing is carried out under stirring...

Embodiment 1

[0049] (1) The base material, expanded graphite, and polypropylene staple fibers are first mixed for 20 minutes, and then silica sol (concentration is 25wt%), silane coupling agent, and water are added for the second mixing for 20 minutes to obtain a mixture;

[0050] With respect to the base material of 10 parts by weight, the consumption of the water is 80 parts by weight;

[0051] (2) The foaming agent and the inorganic flame retardant are mixed for a third time for 30-50 minutes, then sodium carboxymethyl cellulose and water are introduced, and the foaming liquid is obtained by stirring for 5-10 minutes;

[0052] With respect to 10 parts by weight of foaming agent and inorganic flame retardant, the amount of water used is 120 parts by weight;

[0053] (3) The mixture and the foaming liquid are subjected to the fourth mixing for 30-50min, the fourth mixing is carried out under stirring, and the stirring rate is 100-150r / min; It is a paste, and after injection molding, it i...

Abstract

The invention relates to the technical field of soft porcelain, in particular to a lightweight flexible soft porcelain and a preparation method thereof, comprising the following components in parts by weight: 100 parts of base material, 0.6-3 parts of expanded graphite, and 0.2-0.5 parts of polypropylene short fibers , 0.6-3 parts of silica sol, 8-15 parts of inorganic flame retardant, 1-2.4 parts of silane coupling agent, 0.2-0.5 parts of foaming agent, and 0.5-1.5 parts of sodium carboxymethyl cellulose. The light and flexible soft porcelain has high strength, good flexibility, light weight, good tear resistance and high elongation at break, has a porous structure, and has the functions of absorbing odor and flame retardant, and does not need to add a large amount of inorganic fillers, making full use of scrap.

Description

technical field [0001] The invention relates to the technical field of soft porcelain, in particular to a lightweight flexible soft porcelain and a preparation method thereof. Background technique [0002] Soft porcelain is a new type of flexible surface decoration material, which is obtained by forming water-based polymer emulsion and inorganic substances such as cement, soil, quartz sand or mineral powder. It is an ecological and environmental protection building material. The appearance of soft porcelain is similar to that of ceramics, but it lacks the cold, heavy and fragile texture of traditional ceramic materials. Low cost, convenient construction, suitable for building decoration such as exterior walls, interior walls and ground, which greatly enriches and beautifies people's living and working environment. [0003] With the development of technology, people have successively developed a wide variety of soft porcelain, such as imitation stone, imitation leather grain...
