Problems solved by technology

However, vitrified microbead thermal insulation mortar has disadvantages such as low strength and long solidification time. Generally, the solidification time exceeds 12 hours, resulting in a relatively prolonged construction period.
[0005] In the patent application number 201410233074.X, a high-strength vitrified microbead thermal insulation fireproof mortar is prepared by adding polypropylene fiber to increase its strength to prepare high-strength thermal insulation fireproof mortar, but polypropylene fiber itself is an organic material and belongs to the combustible category. This leads to a relatively low fireproof temperature of the fireproof mortar

Abstract

The invention provides dry-mixed mortar which is prepared from the following raw materials in parts by weight: 100- 150 parts of a modified polyurethane / diatomite composite material, 20-30 parts of expanded vermiculite, 25-35 parts of hollow glass beads, 5-12 parts of medium sand, 7-18 parts of sodium carboxymethyl cellulose, 15-30 parts of gypsum, 5-10 parts of EVA rubber powder, 3-7 parts of styrene, 3-7 parts of a chlorine salt antifreezing agent, 1-5 parts of an aliphatic water reducing agent, 10-20 parts of fly ash and 10-15 parts of a mineral admixture. The dry-mixed mortar is good in cohesiveness, high in strength, high in waterproof capacity and good in thermal-insulation fireproof effect, and has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a dry powder mortar and a preparation method thereof. Background technique [0002] Dry powder mortar refers to a granular or powdery physical mixture of dry and sieved fine aggregates, inorganic binders, water-retaining thickening materials, mineral admixtures and additives in a certain proportion, packed in bags or It is transported to the construction site in bulk and can be used directly after mixing with water. Compared with traditional on-site mixing mortar, dry powder mortar has the following advantages: (1) excellent quality; (2) rich variety; (3) good construction performance; (4) easy to use; (5) green and environmentally friendly; (6) economical . [0003] Commonly used building insulation materials are mainly divided into organic materials, such as polystyrene board, polyurethane, rubber powder particles, etc.; and inorganic materials, such as aerated con...
