Embodiment 1

[0018] Embodiment one: a kind of silicon PU and PU plastic field spraying construction technique, this technique comprises the following steps:

[0019] 1) Treat the site, remove oil stains, cement blocks, etc., and prevent oil stains, cement blocks and other impurities from affecting the laying;

[0020] 2) leveling the field;

[0021] 3) The base part of the cement is cleaned with a mixture of water and hydrochloric acid, and then the site is washed with clear water. The mixing ratio of water and hydrochloric acid in the mixture is 1:1, and the base part of the cement is treated with a mixture of water and hydrochloric acid. The purpose of cleaning is to use hydrochloric acid to slightly corrode the surface of the cement, so that the cement is fully exposed and prepared for the laying of the plastic, so that when the plastic is laid on the cement foundation, it can be fully bonded to the exposed cement , to improve the grip performance of plastics;

[0022] 4) Use primer f...

Abstract

The invention relates to a construction technology for spraying silicon PU and PU plastic cement sites. The technology comprises the following steps: (1) processing the sites, and clearing oil stains, cement blocks and the like; (2) leveling the sites; (3) for a cement base part, cleaning the sites by using mixed liquid of water and hydrochloric acid, and then washing the sites by clear water; (4) carrying out prime coat by adopting primer, wherein the primer is formed by adding acetic ether which accounts for 10 to 25% of one-component glue into the one-component glue; (5) successively spraying a bottom layer PU and a strengthening layer PU by a sprayer; (6) spraying topcoat; (7) making lines. The technology has the advantages of reasonable technological step arrangement, convenience in construction, good construction effect and the like. Besides, the gripping performance of plastic cement can be improved, the phenomenon that the plastic cement is bosomy is effectively avoided, the service life of plastic cement runways is prolonged, the surface flatness of a PU court is ensured, and the scratches scraped by the traditional rakes on the runways are avoided.

Description

technical field [0001] The invention relates to the technical field of PU court construction, in particular to a construction process for spraying silicon PU and PU plastic courts. Background technique [0002] PU court material (LH320) is a new generation of court material developed on the basis of PU court material. The material is scientifically combined with polyurethane (PU) materials and materials containing organic silicon components. The produced materials are used on the court surface layer, which fundamentally and effectively solves the problem of PU court materials in professional performance and environmental protection construction. , service life, daily maintenance and other deficiencies, with revolutionary innovative performance, is a new generation of environmentally friendly products to replace two-component PU. The characteristics of the coating are as follows: Unique: Silicone PU contains organic silicon components, and organic silicon has the characteris...
