Abstract

The invention discloses a pavement moisture permeameter which comprises a metal housing, wherein the metal housing is subjected to filming treatment; the filming treatment comprises the following steps: 1) sequentially putting 2-3 weight parts of an acrylic resin, 3.0 weight parts of diethyl bromide carbonate, 1.5 weight parts of polymerized flax seed oil, 0.7 weight part of a high chlorinated polyethylene resin into 50 weight parts of deionized water, and stirring uniformly; 2) further sequentially adding 11.0 weight parts of vinyl ethyl carbonate, 8.0 weight parts of hydroxy propyl methylcellulose, 1.8 weight parts of isocaprylic acid and 1.2 weight parts of a borosilicate glass material, continuously stirring till sufficient and uniform mixing so as to obtain a filming treatment solution; 3) putting the metal housing into the filming treatment solution, taking out, and baking. The surface of the metal housing of the pavement moisture permeameter is covered by a protection film, sothat the pavement moisture permeameter is good in performance and high in surface smoothness.

Description

technical field [0001] The invention relates to a pavement moisture infiltration meter. Background technique [0002] The existing pavement moisture infiltration meter needs to be improved in anti-oxidation, abrasion resistance, corrosion resistance, rust resistance, heat resistance, cold resistance and weather resistance of the metal shell, and the surface finish is not ideal enough. Contents of the invention [0003] The purpose of the present invention is to provide a road surface water penetration meter, the surface of the metal shell is covered with a protective film, which has excellent oxidation resistance, abrasion resistance, corrosion resistance, rust resistance, heat resistance, cold resistance, weather resistance, and the surface High finish. [0004] In order to achieve the above object, the technical solution of the present invention is: a road surface moisture permeation meter, which includes a metal shell, and the metal shell is treated with a film, and th...
