"Gaishitu" products won the invention patent certificate

Recently, ORIENTAL YUHONG (ORIENTAL YUHONG) produced the "Gaseco" series of environmentally friendly one-component polyurethane waterproof coating products won the invention patent certificate.

Chinese invention patent, patent number: ZL202010238421.

3

The invention discloses an internal plasticizing type polyether, a preparation method thereof, a single-component polyurethane waterproof coating and a coating composite construction structure.

The raw material composition of the one-component polyurethane waterproof coating includes: internal plasticizing polyether, polyether with more than two functionalities, plasticizer, filler, diphenylmethane diisocyanate, catalyst com" href="http://">coating online coatingol.

The beneficial effects of the present invention:

1.

The present invention adopts a self-made internal plasticized polyether solution to achieve the effect of low viscosity, which can reduce the amount of plasticizer and reduce migration and precipitation.
 

2.

The present invention does not add volatile media, has very few volatile organics during the curing process, and basically has no volume shrinkage during the film forming process; does not use organic solvents, has a high solid content, does not need to use surfactants, is more environmentally friendly, and has no free formaldehyde.
 

3.

Through lightweight technology, low density and high solid content, the present invention greatly increases the effective coating rate of coatings, can effectively reduce transportation costs and save manpower.

4.

The present invention solves the bubble problem in the curing process, and the film is dense, without bubbles, and without defects, and improves the reliability of the waterproof coating as a waterproof layer.

5.

The present invention uses MDI instead of traditional TDI to solve the problem of free TDI toxicity.

6.

The NCO group activity of MDI is much higher than that of TDI, which helps to improve the slow drying speed of polyurethane waterproof coatings at low temperatures, and can be used in low temperature environments below 0°C.

The patent was applied for on March 30, 2020, and the authorization was announced on January 26, 2021.

During the examination process of invention patents, the State Intellectual Property Office highly recognized the inventiveness of the present invention and granted priority examination and rapid authorization to realize patent protection for innovative products.

The patented innovative product-"Gausco" series of solvent-free one-component polyurethane waterproof coatings has passed the strict environmental certification of the European building material environmental performance certification authority, Germany, GEV.

The product does not add solvents, and the content of harmful substances is less than 10% of the current domestic environmental protection standards for waterproof coatings such as national standards, green standards, environmental standards, industry standards, and landmarks.
Low density, high effective solid content, high coating rate.

The technology was identified as an international leading technology by the China Building Materials Federation, and the project won the second prize of the China Building Materials Federation and the Chinese Ceramic Society Building Materials Science and Technology Progress Award.
