Embodiment Construction

[0028] Such as Figure 1 to Figure 6 As shown, it is a binder used for perlite insulation products in the present invention. The raw materials of the binder include Shuangfei powder, white cement, calcium silicate powder, thickener, redispersed latex powder, and pregelatinized tapioca starch and water, the parts by weight of each component are:

[0029]

[0030]A method for preparing a binder for perlite thermal insulation products, which uses the above-mentioned raw materials and a two-way preparation device for preparation. The two-way preparation device includes a preparation housing 1 , a first placement base 2 and a second placement base 3 , and the first placement base 2 and the second placement base 3 are fixed at both ends of the preparation housing 1 . The first connecting plate 4 , the second connecting plate 5 and the third connecting plate 6 are provided in the preparation shell 1 in order from top to bottom, and the supporting rod 7 is between the first connec...

Abstract

The invention discloses an adhesive for an adiabatic pearlite product and a preparation method of the adhesive. The adhesive is prepared from raw materials as follows: heavy calcium carbonate, white cement, calcium silicon powder, a thickening agent, redispersible latex powder, pregelatinized cassava starch and water. The preparation method comprises the following steps: (a), adjusting a region between a second connecting plate and a third connecting plate; (b), mixing heavy calcium carbonate with the white cement; (c), preparing glue; (d), discharging the mixture of heavy calcium carbonate and white cement into the glue for mixing; (e), collecting the adhesive; (f), cleaning a two-way preparation device. Heavy calcium carbonate and the white cement are fully mixed and guided, the water-soluble glue is prepared from the pregelatinized cassava starch and water through mixing, the whole two-way preparation device is then rotated by 180 degrees to discharge the mixture of heavy calcium carbonate and white cement into the glue for mixing and stirring, the mixing speed is high, preparation space is small, and the preparation cost can be effectively reduced; the prepared adhesive is cured more quickly and has higher strength and better temperature resistance.

Description

technical field [0001] The invention belongs to the technical field of adhesive products, and in particular relates to an adhesive used for perlite thermal insulation products and a preparation method thereof. Background technique [0002] Expanded perlite has been researched and produced in foreign countries as early as the late 1940s and early 1950s. Today, it has developed greatly in product variety and output. According to information, the world's perlite output is more than three times that of vermiculite. Perlite accounts for a large proportion of the light construction material market in the United States and Europe. my country began to research and produce expanded perlite in 1965, and the product variety has developed from a single expanded perlite to a variety of expanded perlite products made with different binders. With the rapid development of my country's industry and agriculture, especially in today's energy shortage situation, many industries have put forwar...
