Marine light filling dressing

Abstract

Marine light filling dressing is formed by mixing and stirring 8-20 meshes quartz sand, general silicon 42.5# cement, expanded perlite, ceramic sand, rubber powder, tartaric acid and an efficient water reducing agent. The raw materials comprise, by weight, 15%-25% of the 8-20 meshes quartz sand, 25%-35% of the general silicon 42.5# cement, 5%-7% of the expanded perlite, 25%-35% of the ceramic sand, 5%-7% of the rubber powder, 2% of the tartaric acid and 2% of the efficient water reducing agent. The marine light filling dressing has the advantages of being light in weight, small in density, good in adiabatic and fire-proof performance and the like.

Description

technical field [0001] The invention relates to a marine dressing, in particular to a filling dressing. Background technique At present, other materials need to be used for leveling the arched part of the ship, the padding part of the tile in the wet space, and other thermal insulation and heat insulation areas. This material is the filling material. The existing filling material is mainly sandstone concrete. Although sand and gravel concrete plays a certain filling role, there are still deficiencies in practical application. Due to the heavy weight of sand and gravel concrete, it not only brings inconvenience to the construction, but also undoubtedly increases the construction area and even the weight of the ship after construction; sand and gravel concrete is a large particle material with a high density. The area cannot be filled; in addition, the thermal insulation and fire resistance of sandstone concrete are not ideal. Contents of the invention The purpose of th...

Problems solved by technology

At present, other materials need to be used for leveling the arched part of the ship, the padding part of the tile in the wet space, and other thermal insulation and heat insulation areas. This material is the filling material. The existing filling material is mainly sandstone concrete. Although sandstone concrete plays a certain filling role, there are still deficiencies in practical application.

Due to the heavy weight of sand and gravel concrete, it not only brings inconvenience to the construction, but also undoubtedly increases the construction area and even the weight of the ship after construction; sand and gravel concrete is a large particle material with a high density. The area cannot be filled; in addition, the heat insulation and fire resistance of sandstone concrete are not ideal
