A kind of easy demoulding aluminum alloy formwork and preparation method thereof

Abstract

The invention relates to the technical field of aluminum alloy templates, in particular to an easily-demoulded aluminum alloy template and a preparing method thereof. The aluminum alloy template comprises an aluminum alloy base body and a demoulding layer attached to the surface of the aluminum alloy base body. Raw materials for preparing the demoulding layer include, by weight, 1-5 parts of polyvinyl alcohol, 4-6 parts of stearic acid, 3-5 parts of octadecanamide, 4-8 parts of konjac glucomannan, 15-20 parts of konjaku flour, 15-20 parts of sodium alga acid, 1-3 parts of sodium borate, 5-7 parts of modified shell powder, 5-10 parts of modified silicon dioxide, 2-4 parts of aluminum sulfate, 2-6 parts of sodium methyl silicate, 1-3 parts of sodium dodecyl sulfate and 0.3-0.7 part of organic silicon defoamer. The demoulding layer is directly formed on the surface of the aluminum alloy base body, demoulding is easier, the cyclic usage frequency is larger, the concrete demoulding qualityis improved to a certain degree, and the demoulding efficiency of the aluminum alloy template is improved.

Description

technical field

[0001] The invention relates to the technical field of aluminum alloy formwork, in particular to an aluminum alloy formwork with easy release and a preparation method thereof. Background technique

[0002] Building formwork is an essential building construction material and an important tool, which plays an important role in the construction process of cast-in-place concrete. Aluminum alloy formwork has been widely used in building construction in developed countries abroad, and was introduced into China at the beginning of the 21st century. As a new type of building formwork, aluminum alloy formwork has the advantages of light weight, easy assembly and disassembly, high bearing capacity, not easy to rust, and many turnover times, which is incomparable to traditional formwork such as wood formwork, combined steel formwork and all-steel large formwork. advantages and convenience. After more than ten years of development, aluminum alloy formwork has been wide...
