Abstract

The invention discloses a paint assisting in reducing building weight. The paint is composed of the raw materials of, by weight, 73-80 parts of high-density polyethylene, 0.7-1 part of methyl ethyl ketoxime, 0.1-0.2 parts of potassium tungsate, 2-3 parts of zinc dihydrogen phosphate, 1-2 parts of polyvinyl pyridine, 15-20 parts of bauxite ceramic sand, 0.7-2 parts of magnesium disodium edetate, 3-5 parts of iron tailing powder, 1-2 parts of dipropylene glycol, 2-3 parts of tea saponin, 0.6-1 parts of hydrolyzed polymaleic anhydride, 4-6 parts of polyisobutylene, 4-7 parts of tributyl citrate, 1-2 parts of tetrahydrofurfuryl alcohol, 0.4-1 part of 2-mercapto benzothiazole, 0.5-1 parts of ammonium octamolybdate, 1-2 parts of saturated stearamide, 0.3-1 parts of urea, and 1-2 parts of baking powder. According to the invention, bauxite ceramic sand is adopted as a filling material, such that the paint has high density and light weight, and the paint assists in reducing building weight. Also, the bauxite ceramic sand has high high-temperature resistance, high-pressure resistance and corrosion resistance. When the paint is exposed on building surface for a long time, paint bonding strength and stability are not reduced. The paint has a long service life and good protection effect.

Description

Background technology

Object is exposed among air, is subject to the erosion of oxygen, moisture etc., causes the breakoff phenomenons such as corrosion of metal, foxy, cement weathering.Be coated with coating at article surface, form layer protecting film, can stop or postpone generation and the development of these breakoff phenomenons; the work-ing life of various material is extended; therefore a kind of coating efficiently can play good protected effect, reduces the wastage rate of object, economizes on resources.

Along with the development of coating industry; with acrylate, PVC polymkeric substance etc. for the product of coating is also a lot; but some coatings have slight corrodibility, dust suction, thermotolerance, weathering resistance poor; and the stable chemical performance of PE, good weatherability; nontoxic, pollution-free, density is low; the application of various material can be widely used in, good protected effect can be played.

Summary of the invention

The object of the invention is just to provide one can reduce buildings deadweight coating.

The present invention is achieved by the following technical solutions:

One can reduce buildings deadweight coating, and it is made up of the raw material of following weight parts:

High density polyethylene(HDPE) 73-80, methyl ethyl ketoxime 0.7-1, potassium wolframate 0.1-0.2, primary zinc phosphate 2-3, polyvinyl pyridine 1-2, aluminium vanadine ceramsite sand 15-20, ethylenediamine tetraacetic acid disodium magnesium salt 0.7-2, iron tailings ground-slag 3-5, dipropylene glycol 1-2, tea saponin 2-3, hydrolytic polymaleic anhydride 0.6-1, polyisobutene 4-6, tributyl citrate 4-7, tetrahydrofurfuryl alcohol 1-2, 2-mercaptobenzothiazole 0.4-1, ammonium octamolybdate 0.5-1, saturated octadecanoyl amine 1-2, urea 0.3-1, baking powder 1-2.

Reduce a preparation method for buildings deadweight coating, it is characterized in that comprising the following steps:

Saturated octadecanoyl amine is joined in 15-20 times of water, stirs, add baking powder, tea saponin, be uniformly mixed 2-3 minute at 70-80 DEG C, obtain dispersion liquid; The 30-40% of polyisobutene with tributyl citrate weight is mixed, after stirring, adds tetrahydrofurfuryl alcohol, insulated and stirred 4-6 minute at 50-60 DEG C, add iron tailings ground-slag, be stirred to normal temperature, dry abrasive dust, obtain powder; Aluminium vanadine ceramsite sand, potassium wolframate are mixed with the 4-10% of high density polyethylene(HDPE) weight, ball milling is even, mixes with above-mentioned powder, join after stirring in dispersion liquid, rising system temperature is 60-65 DEG C, drips urea, after dropwising, 400-600 rev/min of dispersed with stirring 20-30 minute, dries, and mixes with each raw material of residue, send into twin screw extruder, carry out melting, extrude, cross 60-100 mesh sieve, buildings deadweight coating described in obtaining, can be reduced.

Using method:

Advantage of the present invention is:

Coating of the present invention adopts aluminium vanadine ceramsite sand as filler; density is high, light weight; buildings deadweight can be reduced; aluminium vanadine ceramsite sand has very strong high temperature resistant, high pressure, corrosion resistance nature simultaneously; be chronically exposed to cohesive strength and stability that building surface also can not reduce coating; long service life, protected effect is good.
