Abstract

The invention discloses high-levelling property paint. Raw materials of the paint comprises, by weight, 76-85 parts of high density polyethylene, 3-4 parts of levelling agent PV99, 1-2 parts of N,N-diethylaniline, 3-5 parts of locust bean gum, 1-2 parts of sodium fluoborate, 1-2 parts of polyoxy tertramethylene ether glycol, 3-4 parts of alumina silicate fiber, 0.3-0.5 parts of tea tree oil, 5-7 parts of an acrylonitrile-butadiene-styrene copolymer, 3-5 parts of silicon carbide, 7-10 parts of talcum powder, 2-4 parts of palm wax and 17-20 parts of a composite filling material. The paint is good in adhesive force, weatherability, wear resistance, levelling property and anti-temperature change property and is smooth in surface. The raw materials of the paint are easy to obtain and the paint is low in cost and cheap in price. The cohesiveness between the paint and a coated part is strong and the coating is uniform and is good in stability. The paint enables the coated part to obtain a great protective effect and is long in service life.

Description

A kind of coating of high-leveling

Technical field

The present invention relates generally to a kind of coating, relates in particular to a kind of coating of high-leveling.

Background technology

Object is exposed among atmosphere, 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; extended the work-ing life of various materials; therefore a kind of coating efficiently can play good protection effect, reduces the wastage rate of object, economizes on resources.

Along with the development of coating industry; taking acrylate, PVC polymkeric substance etc. as the product of coating 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 materials can be widely used in, good protection effect can be played.

Summary of the invention

The object of the invention is just to provide a kind of coating of high-leveling.

The present invention is achieved by the following technical solutions:

A coating for high-leveling, it is made up of the raw material of following weight parts:

High density polyethylene(HDPE) 76-85, flow agent PV99 3-4, N, N-Diethyl Aniline 1-2, Viscogum BE 3-5, Sodium tetrafluoroborate 1-2, PTMG 1-2, aluminum silicate fiber 3-4, tea tree oil 0.3-0.5, acrylonitrile-butadiene-styrene copolymer 5-7, silicon carbide 3-5, talcum powder 7-10, palm wax 2-4, compounded mix 17-20;

Described compounded mix is made up of the raw material of following weight parts:

Agalmatolite 25-30, fine hair powder 10-13, methylisothiazolinone 2-3, linear low density polyethylene 15-25, Xylo-Mucine 1-2, tricresyl phosphate (butoxyethyl group) ester 1-2, Terpineol 350 1-2;

Above-mentioned agalmatolite is calcined to 1-2 hour at 600-700 DEG C, after discharging is cooling, add methylisothiazolinone, linear low density polyethylene, Xylo-Mucine is joined in 6-10 times of water, after stirring, add fine hair powder, at 60-70 DEG C, be uniformly mixed 4-6 minute, mix with powder obtained above, add the each raw material of residue, fully grind, dry, cross 60-80 mesh sieve, obtain described compounded mix.

A preparation method for the coating of high-leveling, comprises the following steps:

Above-mentioned glass fibre is mixed with aluminium dihydrogen phosphate, at 70-80 DEG C, be uniformly mixed 3-5 minute, add barium stearate, be stirred to normal temperature, add the each raw material of residue, mix, send into twin screw extruder, carry out melting, extrude, cross 60-100 mesh sieve, obtain the coating of described high-leveling.

Using method:

If be sprayed on the high temperature materials such as steel pipe, coating piece can be heated to suitable temperature, generally, between 200-350 DEG C, then coating of the present invention is dispersed on coating piece uniformly by electrostatic spraying, after coating melting, can be bonded in and on coating piece, forms plastic film;

If be sprayed on the material of the non-refractory such as cloth, fiberboard, can, by paint heating melting, then coating piece be infiltrated, can exert pressure to control by rubber rollers the thickness of glue-line to coating, then through plasticizing, cooling.

Advantage of the present invention is:

Paint adhesion of the present invention, weathering resistance, wear resistance, temperature-change resistance are good, smooth surface, good leveling property, and raw material is easy to get, low price; cost is low, and between coating and coating piece, cohesiveness is strong, and coating is even; good stability, can play good protection effect, long service life to coating piece.
