A kind of uv-resistant polyol polyurethane imitation teak self-leveling material and its application

Abstract

The invention discloses a UV-resistant polyol polyurethane imitation teak wood self-leveling material and an application thereof, belonging to the technical field of building materials. It is composed of independently packaged color A component and transparent B component at a mass ratio of 1–3:1, the density of the mixed liquid is 0.8–1.33kg / L, and the color A component is composed of 39%–48 % polyol elastic polyurethane resin, 0.5%–1% bentonite, 45%–50% filler and 6%–10% functional additives, polyol elastic polyurethane resin is composed of 40%–45% plant polyol, 40%–45 % diisocyanate and 10%–20% pigments, transparent component B is a transparent curing agent, used for ship deck decoration ground with rolling resistance and flexibility anti-fatigue properties, waterproof and non-slip, wear-resistant and weather-resistant, UV-aging and anti-aging It has good impact and other properties, does not fade, and its vision and touch are comparable to native teak, which is green and safe.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a self-leveling material of UV-resistant polyol polyurethane imitating teak wood and an application thereof. Background technique [0002] Wood-like materials refer to a class of materials that have similar appearance, texture, physical and mechanical strength, and mechanical processing performance to wood materials, and can replace traditional wood materials in some fields. Traditional wood-like materials such as reinforced concrete surface wood-like materials often need log materials as molds to obtain surface wood texture, which is close to wood products in appearance and has high strength, and is mostly used in large and medium-sized antique buildings; traditional wood-plastic materials contain wood materials, and their The product is easy to absorb moisture, and the waterproof performance needs to be improved. In order to achieve the imitation wood gra...

AI Technical Summary

Problems solved by technology

Traditional colored self-leveling cement generally has disadvantages such as poor tinting strength, uneven color, and easy discoloration and fading. The environmentally friendly colored cement-based self-leveling material disclosed in the patent (CN102190463B) uses tricalcium aluminate and tricalcium silicate with less content. The combination of cement, ultra-fine pigment and dispersant has uniform color after curing and is not easy to fade. It has good crack resistance and ensures the flow and leveling performance of self-leveling materials. Heavy weight, not suitable for ship exterior decoration ground

Traditional epoxy self-leveling coating materials are brittle, have poor aging resistance, and are prone to discoloration, drumming, cracking, powdering, and delamination. They are also not suitable for outdoor coating, and the construction of epoxy self-leveling is harmful to The requirements for ambient temperature and humidity are relatively strict, the low-temperature film-forming performance is poor, and the construction period is relatively long

In addition, the disclosed polystyrene imitation teak product of patent application (CN106046582A) and (CN103753680A) disclosed imitation teak heavy bamboo flooring are not suitable for cruise ships and passenger ship exterior floors that require high quality and appearance
