Embodiment 1- Embodiment 10

[0039] The high thixotropic colored marble glue of Examples 1 to 10, the specific components are listed in Table 1 (the data of marble glue in the table are parts by weight):

[0040] Table 1 High thixotropic colored marble adhesive components and preparation process conditions

[0041]

[0042]

[0043] The high thixotropic colored marble glue described in Examples 1 to 10 of the present invention can be prepared by accurately weighing the formula components of Examples 1-10 in Table 1, and then following the process conditions in Table 1 and performing ultrasonic dispersion at the same time.

[0044] According to GB / T 2794-2013 "Determination of Viscosity of Adhesives", the high thixotropic colored marble glue prepared above was used with SNB-3 digital rotational viscometer (Shanghai Nirun Intelligent Technology Co., Ltd.), and the 4th grade was selected. The rotors were tested at 35°C, 45°C, 55°C and 65°C at the speeds of 6r / min and 60r / min respectively, the viscosity...

Embodiment 16

[0074] Example 16: Stir at high speed under a negative pressure of 0.08Mpa and a rotating speed of 1500r / min, and carry out ultrasonic dispersion at the same time, and the duration is 30 minutes;

Embodiment 17

[0075] Example 17: Stir at high speed under a negative pressure of 0.1 Mpa and 1500 r / min at a rotational speed, and at the same time carry out ultrasonic dispersion for 30 minutes.

[0076] As shown in Table 5, under the process conditions of 1500r / min high-speed stirring under normal pressure and 1500r / min high-speed stirring under normal pressure and 1500r / min high-speed stirring under normal pressure, and ultrasonic dispersion at the same time or under negative pressure 0.08Mpa Stir at a low speed of 800r / min, and carry out ultrasonic dispersion at the same time. The duration of 30 minutes cannot reach the process conditions described in the present invention. The negative pressure is 0.08Mpa or 0.1Mpa, and the rotating speed is under the negative pressure state of 1500r / min. The effect of ultrasonic dispersion can only make the high thixotropic colored marble glue overcome the shortcomings of existing marble glue that is thin or even flowing at medium and high temperature ...

Abstract

The invention discloses high-thixotropy colored marble adhesive. The high-thixotropy colored marble adhesive comprises, by weight, 100 parts of pre-accelerated unsaturated polyester resin, 3-5 parts of liquid thixotropic agents, 5-10 parts of powder thixotropic agents, 50-250 parts of fillers and 0-7 parts of pigment. The liquid thixotropic agents comprise one or a plurality of types of glycerol,diethylene glycol and triethylene glycol; the powder thixotropic agents comprise polyamide wax, precipitated silicon dioxide and talc powder. The high-thixotropy colored marble adhesive has the advantages that the high-thixotropy colored marble adhesive is prepared by the aid of a method for carrying out high-speed stirring in negative-pressure states under the negative pressures of 0.08-0.1 Mpa at the rotational speeds not lower than 1500 r / min and carrying out ultrasonic dispersion, the method is simple, the high-thixotropy colored marble adhesive prepared by the aid of the method is excellent in thixotropic property, and the problem of dilution or flowing can be solved by the aid of the high-thixotropy colored marble adhesive even at the moderate and high temperatures (of 35-65 DEG C).

Description

technical field [0001] The invention relates to a marble glue and a preparation method thereof, more specifically, to a highly thixotropic colored marble glue and a preparation method thereof. Background technique [0002] As a stone adhesive, marble glue has been widely used in the field of stone construction, and it is the most widely used in the field of bonding. This requires that the marble glue cannot be thinned or flowed so as not to contaminate the stone, that is, the thixotropy of the marble glue ( When the object is sheared, the consistency becomes smaller, and when the shearing is stopped, the consistency increases again) is better. [0003] At present, manufacturers often use thixotropic agents to solve such problems, such as hydrogenated castor oil and nano-scale powder thixotropic agents mentioned in the patent 201010201032.X "A Stone Jointing Adhesive". However, the marble glue produced by thixotropic agents in China is only suitable for indoors with low temp...
