Abstract

The invention discloses a kind of production methods of glass reflective coating.It is an object of the invention to overcome existing reflectance coating of high cost, complex process, by constantly testing improvement, provide it is a kind of it is simple for process, cost is relatively low, the production method of the good energy-saving glass reflective coating of reflecting effect.This method, using NaCl and KCl powders as reflecting material, is formed using polyethylene film as base material by high temperature bond.

Description

A kind of production method of glass reflective coating

Technical field

The present invention relates to a kind of preparation method of energy-saving building materials, more particularly to a kind of making side of glass reflective coating Method.

Background technology

With the shortage of mankind's energy and resource, people also increasingly pay attention to building energy conservation.In building heat dissipation and heat absorption In, the proportion of glass pane or cladding glass accounts for the 10%~30% of common building, therefore the field is that emphasis is needed to consider 's.Generally hollow glass is used to make a decision the heat transfer of glass at present.High reflection glass is generally used for the heat radiation of glass The shortcomings that glass or patch reflectance coating avoid, and used reflectance coating generally existing is of high cost, complex process.

Invention content

It is an object of the invention to overcome existing reflectance coating of high cost, complex process, changed by constantly testing Into, provide it is a kind of it is simple for process, cost is relatively low, the production method of the good energy-saving glass reflective coating of reflecting effect.This method is with poly- Vinyl film is base material, using NaCl and KCl powders as reflecting material, is formed by high temperature bond.

The purpose of the present invention is what is be achieved through the following technical solutions：

A kind of production method of glass reflective coating, production method are：Analytically pure anhydrous NaCl and KCl crystal are first pressed into matter Amount is than 1: 1.55 mixing；NaCl and KCl mixtures are machined to grain size at 1~100 nanometer with airflow milling again；By 0.3~0.5 The sealed polyethylene plastic of mm of thickness is heated to 105 ± 3 DEG C, then NaCl the and KCl mixture powders processed are uniformly spread out It is layered on sealed polyethylene plastic, makes powder that film surface be completely covered, film is cooled to room temperature, removal is not viscous with film Powder even, you can obtain energy-saving glass reflective coating.

Advantages of the present invention is with effect：

The present invention is using polyethylene film as base material, and using NaCl and KCl powders as reflecting material, raw material is easy to get, and makes work Skill is simple, lower cost, high to the reflectivity of infrared ray.
