Problems solved by technology

Although this thermal insulation material can basically meet the requirements of national industry standards and regulations, due to the poor combustion performance and low strength of polystyrene particles, it is prone to irreparable quality loss control; while the thermal insulation mortar product using vitrified microspheres alone has high water absorption and thermal conductivity. Large, poor insulation performance

Example Embodiment

[0035] Example one:

[0036] A glass benzene composite thermal insulation mortar, which is composed of the following parts by weight of raw materials:

[0037] 25 parts of cement 15 parts of mineral powder

[0038] Vitrified beads 10 parts Polystyrene particles 1 part

[0039] Redispersible latex powder 2 parts Polypropylene fiber 0.1 parts

[0040] 0.1 part of cellulose ether.

[0041] The cement uses 42.5 ordinary Portland cement; the diameter of the vitrified beads is 0.5 to 1.5 mm; the diameter of the polystyrene particles is 2 to 5 mm; the length of the polypropylene fiber is 5 to 20 mm ; The viscosity of cellulose ether is 100,000.

[0042] The said mineral powder is a kind of highly active powder. Adding mineral powder to the glass benzene thermal insulation mortar can save 30% of the cement consumption, reduce the cost, and also improve the early strength. The compressive strength of 3 days is increased by 10%. , While improving the workability of the mortar, reducing the segreg...

Abstract

The invention discloses glass and benzene composite thermal insulation mortar, which is prepared by the following steps of: weighing cement and mineral powder according to weight part, putting into a mixer, weighing polypropylene fibers, redispersible latex and cellulose ether, putting into the mixer, and uniformly stirring to form a premix; respectively weighing the premix, vitrified micro bubbles and polystyrene granules, adding into a spiral ribbon mixer, stirring the three materials uniformly, and completely opening a bin gate at the bottom of the mixer to obtain the uniformly stirred glass and benzene composite thermal insulation mortar; and packaging the glass and benzene composite thermal insulation mortar by using a packaging machine. The glass and benzene composite thermal insulation mortar has the advantages of low water absorption, small conductivity factor, high strength, and good thermal insulation performance, the flammability can be greatly reduced, the construction efficiency is improved and the manpower is saved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a glass-benzene composite thermal insulation mortar and a preparation method thereof. Background technique [0002] At present, as people have higher and higher requirements for house heat insulation, heat insulation and waterproof technology has gradually developed into a systematic building energy-saving technology, which is used to improve living comfort, prolong the life of buildings, and prevent the loss of heating heat and cold air. Thereby reducing energy consumption. Most of the thermal insulation materials circulating in the domestic market are made of rubber powder polystyrene particle slurry products, mainly composed of fly ash, polystyrene particles, latex, inorganic silicate and other raw materials. Although this thermal insulation material can basically meet the requirements of national industry standards and regulations, due to the poor combustion perfo...
