preparation example Construction

[0018] The present invention also provides a preparation method of a sealant for LOW-E glass, wherein the preparation method comprises: mixing phenolic resin, butadiene rubber, nano-calcium oxide, paraffin, diatomaceous earth, talcum powder and manganese dioxide Mix, make LOW-E glass sealant; Wherein,

[0019] Relative to 100 parts by weight of the phenolic resin, the amount of the butadiene rubber is 20-60 parts by weight, the amount of the nano-calcium oxide is 1-5 parts by weight, and the amount of the paraffin wax is 10-30 parts by weight , the amount of diatomaceous earth is 10-20 parts by weight, the amount of talc powder is 1-10 parts by weight, and the amount of manganese dioxide is 1-10 parts by weight.

[0020] Similarly, in order to make the obtained LOW-E glass sealant better fill the uneven surface at the edge during actual use, in a preferred embodiment of the present invention, relative to 100 parts by weight of the Phenolic resin, the consumption of the butadi...

Embodiment 1

[0027] Mix 100g of phenolic resin, 30g of butadiene rubber, 2g of nano-calcium oxide, 15g of paraffin wax, 13g of diatomaceous earth, 3g of talcum powder and 3g of manganese dioxide at a temperature of 100°C to obtain a sealant for LOW-E glass. Glue A1.

Abstract

The invention discloses a sealant material composition for LOW-E glass and a preparation method of sealant. The composition comprises phenolic resin, butadiene rubber, nano-calcium oxide, paraffin, kieselguhr, talcum powder and manganese dioxide. Relative to 100 parts by weight of phenolic resin, the content of butadiene rubber is 20-60 parts by weight, the content of nano-calcium oxide is 1-5 parts by weight, the content of paraffin is 10-30 parts by weight, the content of kieselguhr is 10-20 parts by weight, the content of talcum powder is 1-10 parts by weight, and the content of manganese dioxide is 1-10 parts by weight. Through the design, the sealant, prepared after mixing at the ratio, for the LOW-E glass can effectively bond the LOW-E glass when actually applied to bonding the LOW-E glass, the concave-convex surfaces of edges can be filled with the sealant, and therefore the good bonding effect is achieved.

Description

technical field [0001] The invention relates to the field of production and preparation of sealants, in particular to a sealant material composition for LOW-E glass and a preparation method of the sealant. Background technique [0002] Low-E glass is low-emissivity glass, which is widely used in daily production and life. In actual use, multiple pieces of Low-E glass are often bonded and used, and in the bonding process, often Due to problems such as film removal technology, the edge of the LOW-E glass is not smooth, which leads to the sealant often not being firmly bonded when bonding. [0003] Therefore, it is an urgent problem to be solved by the present invention to provide a sealant material composition for LOW-E glass that can effectively block air bubbles and greatly improve the bonding performance at the edge of the LOW-E glass and a method for preparing the sealant. Contents of the invention [0004] In view of the above-mentioned prior art, the purpose of the pr...
