Description
Technical field
The present invention relates to the fields of coating, and in particular to anti-skidding superhard fire-retardant floor coatings.
Background technique
With the progress of science and technology, the raising of human living standard, requirement of the people to indoor environment, air quality is got over
Come higher；Modern industry proposes more stringent requirement to terrace simultaneously, such as food, medicine industrial requirements terrace do not rise
Ash, no unwanted volatile are clean dustless；Mechanical industry requires resistance to strong mechanical shock, wear-resistant, can be subjected to fork truck etc. for a long time
The roll off of vehicle is easy maintenance local damage；The industrial plants such as lathe, instrument and meter ground is subjected to various oils and invades
Erosion leakage, it is difficult to thoroughly remove, it is desirable that terrace oil resistivity is good, and chemical industry then requires terrace to be resistant to the corruption of various chemical mediators
Erosion；Therefore with the very fast development of floor coatings technology, in order to adapt to different occasions, environment, floor coatings need to meet phase
The characteristic answered.
Epoxy flooring coating is wear-resisting frequently as multi-functional floor coatings, such as anti-corrosion, anti-skidding, develops to general common
Industry ground slab also has decorative effect in addition to multi-functional requirement.Epoxy flooring coating is in normal use, generally
It is emphasised that wearability and pressure-proof and impact resistance energy, also have means suitable to be produced into the different requirement such as anticorrosion type, there is pole
A small number of customer requirement floor coatings have heat resistance perhaps flame retardant property if any food factory because having oven etc. or electronics
Factory will heat or there is a baking vanish requirement in part factory, and general heat resistance requires to reach 100 DEG C or more, according to such case,
The terrace pan feeding that the good heat-resisting quantity of flexibility can be used strong, it is desirable that the terrace that the place such as high place such as amusement and recreation uses applies
Material has then had to resistance to cigarette butt and has burnt performance, because cigarette butt extreme temperatures when glowing are influenced plus tar etc., often generates
It burns the problems such as yellow.Therefore the multi-functional terrace for having both flame retarding function will be the overdevelopment of the following indoor or outdoors floor coatings
Point.Our company discloses waterborne flame retardant epoxy resin in the patent for having applied for a patent No. CN201610740995.4 before
Coating and preparation method thereof is specifically disclosed and is formulated by tri- component of A, B, C 5:1:1 in mass ratio, and component A is by below by weight

10-25 parts；B component is made of following raw material by weight: 20-25 parts of triethylene tetramine, 3-5 parts of titanium dioxide, pigment 8-
10 parts, 100-110 parts of talcum powder, 30-40 parts of water；Component C is made of following raw material by weight: wetting dispersing agent 1-
3.2 parts, 1.2-1.6 parts of defoaming agent, 1.2-1.8 parts of levelling agent, 15-20 parts of phosphor nitrogen composite combustion inhibitor, hypophosphite fire retardant 5-6
Part, 5-6 parts of phosphate；The waterborne flame retardant epoxy coating is with environmentally friendly, hardness of film is high, excellent in cushion effect, glossiness
The advantages that good and good flame resistance, but in practical applications, urgent need the aspect of performance such as anti-skidding, waterproof, weather-proof, chemical resistance more
Add excellent floor coatings.Grant number is that the Chinese patent of CN103571304B discloses a kind of flame retardant epoxy floor coatings, should
Invention specifically discloses flame retardant epoxy floor coatings and is matched by host agent and curing agent according to the ratio mixing of weight ratio 100:(20-30)
Than composition, the host agent is made of the raw material of following weight: 40-70 parts of epoxy resin, 2-10 parts of diluent, and fire retardant
30-50 parts, 0.01-2 parts of dispersing agent, 0.01-2 parts of defoaming agent, 0.01-2 parts of levelling agent, 1-5 parts of toner；The curing agent is under
The raw material of column weight forms: 30-90 parts of polyetheramine, 10-70 parts of property amine, 1-10 parts of promotor；The flame retardant epoxy terrace
Coating is different from product on the market, can achieve UL94V0 fire-protection rating, the appearance is beautiful and elegant after product construction, and construction party
Just, easily operated, low volatilization or non-volatile, but the hardness of the flame retardant epoxy floor coatings is lower, in anti-skidding, weather-proof, resistance toization
The aspect of performance such as the property learned are poor, therefore the scope of application is restricted.
