Novel exterior wall thermal insulation coating preparation process

Abstract

The invention discloses a novel exterior wall thermal insulation coating preparation process. The preparation process adopts the following preparation machine, the preparation machine comprises a barrel and a stirring device arranged in the barrel, the stirring device comprises a first grinding plate, a second grinding plate and a third grinding plate which are sequentially arranged from top to bottom, a driving device used for driving the second grinding plate to rotate is arranged at the top of the barrel, a flow guide device is arranged at the bottom of the third grinding plate, and a filtering device is arranged below the flow guide device. Raw materials are ground and mixed through mutual friction among the three layers of grinding plates, the materials flow to the bottom of the second grinding plate to be mixed again after being mixed at the top of the second grinding plate, and the second grinding plate is driven by a two-way motor to rotate back and forth so that the mixing efficiency is improved. According to the invention, the mixed slurry is uniformly guided onto the filter screen by utilizing the flow guide device, the slurry on the filter screen is uniformly scraped off by a rotating rod, and the slurry meeting the viscosity requirement falls off from the filter screen, so that the uniformity of the slurry is improved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation coating preparation, in particular to a preparation process of a novel exterior wall thermal insulation coating. Background technique [0002] Thermal insulation coating is a new type of thermal insulation material, a coating that achieves thermal insulation through low thermal conductivity and high thermal resistance. The product is made of high-quality natural minerals with chemical additives and high-temperature adhesives, and is manufactured through pulping, molding, shaping, drying, finished products, and packaging. [0003] The publication number is CN106147442A, and the Chinese invention patent titled "Insulation coating and its preparation method and insulation coating" discloses a preparation method of insulation coating, which includes the following steps: Weigh the following components 15 according to the parts by mass—— 30 parts of main ingredients, 3-22 parts of acrylic po...

Problems solved by technology

[0004] When mixing, use a disperser to mix the raw materials. When mixing, the disperser can only stir the raw materials. For the powdery substances added later, such as heavy calcium carbonate powder, etc., in order to make them blend into the slurry, more stirring is required. For a long time, the efficiency is low, and secondly, it is impossible to grind the powdery substance twice; moreover, there may be uneven mixing, that is, the viscosity of the slurry in different parts is uneven
