Green pavement brick, premixing material thereof and production method of green pavement brick

Abstract

The invention relates to a green pavement brick, a premixing material thereof and a production method of the green pavement brick. The premixing material is composed of a base layer material and a surface layer material. The base layer material contains cement, sand and a water reducing color retention agent, the surface layer material contains cement, sand, green pigment and a water reducing color retention agent, and the water reducing water retention agent is a mixture of 1-2 parts, by weight, of high-performance polycarboxylate superplasticizer and 4-6 parts, by weight, of amino resin. Compared with the prior art, the production method is convenient to implement, simple in process, strong in safety, good in application effect, a manufactured cement brick product has high hardness, and the product has abundant gloss, is resistance to corrosion, heat, boiling water, pollution and chemical medicine and has the electric insulativity, particularly has the good color fading resistant effect, and will not fade within 3-5 years through actual measurement in the Xinjiang region.

Description

technical field [0001] The invention relates to a premix for making green pavement bricks and a production method of the green pavement bricks. Background technique [0002] Most of the existing production methods for making green pavement bricks are: white cement or a mixture of white cement and ordinary Portland cement, adding green pigments, such as iron oxide green powder, pigment green B powder, chromium oxide green powder, etc. The medium sand is mixed evenly in a certain proportion as the fabric layer. Medium sand, gravel or stone chips below 15mm, ordinary Portland cement, high-efficiency water reducer and water are mixed in a certain proportion and fully stirred evenly as the base material. Then it is prepared by forming and curing. [0003] The green pavement bricks made of existing green cement will fade in less than half a year after being damaged by wind, sun, rain, dew, frost, snow, chemical corrosion, and freeze-thaw cycles in an open-air natural environment...
