Abstract
The invention discloses a kind of thermal insulation mortars, are made of the raw material below according to parts by weight：25 35 parts of cement, 30 45 parts of sand, 10 20 parts of pulverized limestone, 8 16 parts of aglite, 5 10 parts of swelling agent, 48 parts of anticrack additive, 28 parts of water-reducing agent, 8 12 parts of polyvinyl alcohol, 69 parts of hydroxypropyl methyl cellulose, 6 13 parts of zeolite powder, 15 20 parts of stalk fibre.The present invention also has both good mechanical property while having good heat-insulating property, the dry contraction of mortar early stage can be reduced by adding stalk fibre, inhibits the generation and growth of microcrack, effectively reduces crackle, amplified medium material continuity, to improve the toughness of mortar；And so that the adhesive property of mortar is enhanced, to improve the cohesive force and flexibility of mortar material in the case that stalk fibre cooperates with swelling agent, anticrack additive, polyvinyl alcohol and hydroxypropyl methyl cellulose；Zeolite powder, which is added, can significantly improve the flexural strength of mortar.
Description
Technical field
The present invention relates to building material technical field, specifically a kind of thermal insulation mortar and its manufacturing method.
Background technology
Thermal insulation mortar is, using cement as gelating material, some property-modifying additives to be admixed, through life using various light materials as aggregate
Production enterprise is stirred and a kind of manufactured premixed dry mortar, a kind of construction material for constructing building insulating layer.
Currently, architectural engineering requirement in China's is higher and higher, market has emerged a large amount of building energy conservation new material, new process；Wherein protect
Warm mortar exterior wall heat insulation system plays the role of considerable in modern high-rise building.Its reliable Construction treatment is by society
It can approve, be most one of the external-wall exterior insulation way of current comprehensive advantage.
Water retentivity of mortar and thermal and insulating performance used in us are all relatively good at present, but resistance to compression, flexural strength be not high,
Poor toughness, tensile strength is low, be easy to cause problems of crack, to limit the use of mortar.
Invention content
The purpose of the present invention is to provide a kind of thermal insulation mortar and its manufacturing methods, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the present invention provides the following technical solutions：
A kind of thermal insulation mortar is made of the raw material below according to parts by weight：
25-35 parts of cement, 10-20 parts of pulverized limestone, 8-16 parts of aglite, 5-10 parts of swelling agent, resists 30-45 parts of sand
Split 4-8 parts of additive, 2-8 parts of water-reducing agent, 8-12 parts of polyvinyl alcohol, 6-9 parts of hydroxypropyl methyl cellulose, 6-13 parts of zeolite powder,
15-20 parts of stalk fibre.
A kind of thermal insulation mortar manufacturing method, includes the following steps：
Step 1：Various raw material are accurately weighed by weight proportion, first by cement, sand, pulverized limestone, aglite, swollen
Swollen dose, anticrack additive, stalk fibre and zeolite powder are uniformly mixed in blender；
Step 2：Suitable water is poured into blender again, and water-reducing agent, polyvinyl alcohol and hydroxypropyl methyl fiber is added
Element continues to stir evenly, mortar is made.
As a further solution of the present invention：The granular size of the sand is between 80-100 mesh.
As further scheme of the invention：The aglite is specially in glass bead or expanded perlite
It is one or two kinds of.
As further scheme of the invention：The swelling agent is entringite.
