Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology and solve the problem that the mortar layer is prone to cracks and the mortar layer falls off due to the decrease in the viscosity of the material and the difference in the expansion rate of the material when the building mortar is in a low-temperature or high-temperature environment for a long time, a construction Mortar and its preparation process

preparation example Construction

[0039] A kind of preparation technology of building mortar, this preparation technology comprises the following steps:

[0040] S1: Put Portland cement, modified expanded perlite powder, marble powder and zeolite into the stirring tank in sequence, control the temperature in the stirring tank at 80-90°C, perform high-temperature drying treatment, and control the stirring during the drying process The rotation speed of the kettle is 60-80r / min, and the mixed powder is obtained by stirring at a constant speed; the Portland cement, modified expanded perlite powder, marble powder and zeolite are stirred and mixed under heating to effectively make each component The moisture absorbed in the material evaporates, and combined with the stirring action, the hardened lumps can be quickly dispersed, thereby speeding up the mixing uniformity between the components;

[0041] S2: After the natural palygorskite is pulverized, it is modified with cetyltrimethylammonium bromide in a reactor to...

Abstract

The invention belongs to the technical field of building materials, and particularly relates to building mortar and a preparation process thereof. A base, a motor and an air compressor are arranged; aguide plate is fixedly connected to the upper surface of the base; a sliding groove is formed in one side, away from a stirring barrel, of the guide plate; symmetrically-designed lead screws are rotationally connected into the sliding grooves; the end, close to the base, of the lead screw extends into a first cavity; the end, located in the first cavity, of the lead screw is connected with an output shaft of the motor through a belt; a sliding block is connected into the sliding groove in a sliding manner; the sliding blocks are engaged with the lead screws; the ends, away from the sliding grooves, of the sliding blocks are sleeved with limiting blocks; a rotating groove is formed in the end, away from the sliding block, of the limiting block; and a first plastering plate and a second plastering plate are hinged in the rotating groove. Mortar spraying and plastering are combined, after mortar is sprayed to the wall surface through high-speed airflow, the mortar sprayed to the wall surface is trimmed through the elastic pressing plate, and therefore forming of a mortar layer is accelerated.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a building mortar and a preparation process thereof. Background technique [0002] Construction mortar is a mortar that bonds masonry block materials (bricks, stones, blocks) into a whole. It is composed of inorganic cementitious materials, fine aggregate and water, and sometimes mixed with certain admixtures. According to its The application can be divided into four types: masonry mortar, plastering mortar (also known as plastering mortar), waterproof mortar and special mortar. In the prior art, the mortar layer applied by plastering mortar on the wall has the function of heat preservation and protection of the wall. However, the plastering mortar in the prior art is very prone to cracks due to expansion or contraction between the mortar materials in the face of high temperature and low temperature environments, which will cause the mortar layer to break and fall off,...
