Inorganic aggregate polyurethane millstone floor as well as preparation method and application thereof

Abstract

The invention discloses an inorganic aggregate polyurethane millstone floor as well as a preparation method and application thereof. The millstone floor sequentially comprises a polyurethane substrate layer, an inorganic aggregate polyurethane millstone layer and a polyurethane transparent surface layer from inside to outside, the inorganic aggregate polyurethane millstone layer is formed by paving a polyol polyurethane self-leveling coating, a diisocyanate curing agent and an inorganic aggregate according to the mass ratio of 1: 1.25: 6, and the inorganic aggregate is selected from recycled glass, marble powder or stone with regular shapes. The polyol polyurethane self-leveling coating is composed of polyol polyurethane resin and a functional aid in a mass ratio of 19: 1. The inorganic aggregate polyurethane millstone terrace belongs to a noise reduction terrace system which is soundproof, seamless and ergonomic, is attractive and comfortable in visual effect, meets the use requirements of high strength, toughness and difficulty in cracking, is convenient to construct and maintain in the later period, is environment-friendly and safe, and can be applied to the ground of public places such as exhibition halls, medical treatment, education, office, entertainment or retail.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an inorganic aggregate polyurethane grindstone floor and a preparation method and application thereof. Background technique [0002] Floor refers to the ground that uses specific materials and processes to construct the original floor and presents a certain decorative and functional floor, such as epoxy self-leveling floor, emery wear-resistant floor, epoxy terrazzo floor, cement-based terrazzo , Epoxy colored sand floor, epoxy anti-static floor, epoxy anti-skid floor, polyurea anti-corrosion floor, polyurethane floor, silicon PU floor, concrete seal curing agent floor, etc. [0003] Terrazzo made of epoxy adhesive is also called epoxy grindstone or organic grindstone. Terrazzo is divided into on-site pouring terrazzo and prefabricated terrazzo floor according to the construction and production process. However, the above-mentioned commonly used terrazzo f...

AI Technical Summary

Problems solved by technology

[0004] (1) The base material is generally rigid cement or thermosetting epoxy resin. The material itself is rigid / brittle and prone to cracking due to environmental changes and uneven stress;

[0005] (2) High hardness, poor flexibility when used in indoor public places affects the comfort experience, and is easy to cause noise pollution;

[0006] (3) The product is not renewable
