Embodiment 1～ Embodiment 10

[0040] The high thixotropic transparent marble glue of embodiment 1~10, specific composition is listed in table 1 (the content data of each component in the form is weight part):

[0041] Table 1 High thixotropic transparent marble glue components and process conditions

[0042]

[0043] Accurately weigh the formulation components of Examples 1 to 10 in Table 1, wherein the mesh size of micron-sized silica is between 400 mesh and 1000 mesh, and prepare each embodiment according to the process conditions in Table 1 (while performing ultrasonic dispersion). Example of high thixotropic transparent marble glue.

[0044] According to GB / T 2794-2013 "Determination of Viscosity of Adhesives", the high thixotropic transparent marble glue prepared above was adopted 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, t...

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 transparent marble glue overcome the shortcomings of existing marble glue that is thin or even flowing at medium and high temperat...

Abstract

The invention discloses a high thixotropic transparent marble adhesive which includes, by weight parts, 100 parts of pre-accelerated unsaturated polyester resin, 3-5 parts of liquid thixotropic agent,5-10 parts of powder thixotropic agent and 10-200 parts of filler. The liquid thixotropic agent includes one or more selected from a group consisting of glycerol, diethylene glycol and triethylene glycol. The powder thixotropic agent includes polyamide wax, precipitated silica and transparent talc. The high thixotropic transparent marble adhesive is prepared by a preparation method of performinghigh-speed stirring at a negative pressure state with a negative pressure of 0.08-0.1 MPa and a rotating speed of no smaller than 1500 r / min and performing ultrasonic dispersion. The preparation method is simple, the prepared marble adhesive is good in thixotropic property, and the problem of being too thin or flowing does not occur even if at medium and high temperatures (35-65 DEG C).

Description

technical field [0001] The invention relates to a marble glue and a preparation method thereof, more particularly, to a highly thixotropic transparent 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 ...
