Abstract
The invention relates to a surface fireproof coating of a wood plastic composite material and a preparation method of the surface fireproof coating. The surface fireproof coating is characterized in that the surface fireproof coating comprises the following raw material components in part by weight: 25 parts of resin matrix, 20 parts of solvent, 45 parts of P-C-N flame retardant system, 5 parts of flame-retardant synergist, 3 parts of filler and a right amount of assistant. The preparation method comprises the following steps of: weighing the raw materials according to the right proportion; placing a charring agent and a foaming agent in a mortar to carry out grinding; adding the solvent, the resin matrix and the assistant and stirring the mixture until colloid is formed; coating the colloid on a matrix of the wood plastic composite material by a scraper until the thickness of the colloid is 0.5mm; and standing. The surface fireproof coating of the wood plastic composite material and the preparation method of the surface fireproof coating have the advantages that the method is simple to operate and has high production efficiency; after the wood plastic composite material is subjected to modification treatment by the method, the flame retardant property of the wood plastic composite material is obviously improved, so that the fireproof heat insulation coating on the surface of the wood plastic composite material is rapidly expanded when the wood plastic composite material is burnt, is coated on the surface of the wood plastic composite material and delays the burning process of the wood plastic composite material; and by high and low temperature, cold water, hot water and acid-base circulating treatment, the coating still has good flame retardant property though being damaged.
Description
Technical field
What the present invention relates to is a kind of wood plastic composite surface fireproof coating and preparation method thereof, belongs to wood and moulds surface fireproof coating technology field.
Background technology
Wood plastic composite is that a class contains basic materials wide, that product category is many, morphological structure is various, the advantage such as have good water-fast and corrosion resistance nature and can be recycled.The theory that it has greatly embodied China's development " recycling economy " and has built " conservation-minded society "; greatly develop this ep-type material; both be beneficial to and protected forest resources and petroleum resources, can open up new road for the extensive comprehensive utilization of waste or used plastics and abandoned biomass resource again.Wood plastic composite is mainly used in structure properties is required lower field, such as industries such as pallet, tr, automotive trim base material, bed board, landscape gardens, account for wood and mould 75 ﹪ of compound articles for use total amount, successfully be applied at present the Beijing Olympic Games and Paralympic Games and and 2010 Shanghai World's Fair in 2008.Yet because natural fiber and various polymkeric substance all are combustible materials, therefore the very easy burning of matrix material can not be put out after catching fire certainly, belongs to inflammable class material, this is so that it is restricted in application process, so flame-retardant wood-plastic composite will become one of emphasis of research.Wood plastic composite can not reach the code for fire prevention design of interior decoration of buildings requirement without fire-retardant finish, is used for the certain disaster hidden-trouble of indoor existence, and fire is to occur the most frequent in all kinds of disasters and have destructive a kind of disaster.At present, generally adopt in wood plastic composite the mode of adding fire retardant to improve the flame retardant resistance of wood plastic composite, but in order to reach preferably flame retardant properties, the addition of fire retardant is very large, not only reduced the mechanical property of material, and increased cost, be difficult to popularize.
In order to address the above problem, a kind of preparation method of surface flame-retardant wood-plastic composite material plate is disclosed in Chinese patent application 200920037412.7.The technical process of the method is that mold pressing has the vegetable fibre reinforced plastic layer between two-layer crystal whisker modified plastic layer, and the sheet material that makes has surface flame-retardant and the higher performance characteristics such as rigidity.The weak point of the method is, in order to reach preferably flame retardant effect, need to carry out modification to whisker, the higher and complex process of cost; The wood-plastic composite board of compression molding preparation, mechanical property especially modulus in flexure are difficult to improve.
Summary of the invention
What the present invention proposed is a kind of wood plastic composite surface fireproof coating and preparation method thereof, its purpose is intended to overcome that existing flame-retardant wood-plastic composite flame retardant properties is low, the amount of being fuming is large, the fire retardant add-on is large, the problems such as cost height and reduction material mechanical performance, the present invention not only can give the flame retardant effect of wood plastic composite excellence, and can to its modifying surface, improve endurance quality.
Technical solution of the present invention: a kind of wood plastic composite surface fireproof coating is characterized in that feed composition and weight part are: 25 parts of resin matrixes, and 20 parts of solvents, 45 parts of P-C-N fire retardant systems, 5 parts of fire retarding synergists, 3 parts of fillers, auxiliary agent is an amount of.The preparation method comprises the steps:
One, takes by weighing raw material according to formula rate;
Two, char-forming agent and whipping agent are placed the mortar last beaker that is transferred to of pulverizing, and add catalyzer, fire retarding synergist and filler, mix;
Three, add solvent, resin matrix and auxiliary agent, and be placed in the magnetic stirrer and fully stir, be stirred to colloid and form;
Four, in the colloid that forms, add an amount of carboxymethyl cellulose, make its fineness reach 75 μ m, finish the preparation of frie retardant coating;
Five, divide some roads to be coated on after treatment the wood plastic composite matrix the above-mentioned frie retardant coating for preparing with scraper plate, concrete grammar is: be coated with first the first coating, be coated with second behind the 12-24h of interval, one time is coated with according to the method is until thickness is 0.5mm again;
Six, the above-mentioned wood plastic composite of processing through surface fireproof is placed physical environment 7 days, test its physicochemical property and fire resistance.
Resin matrix is selected from Resins, epoxy, acrylic resin, Synolac or modifying epoxy resin by organosilicon.
The P-C-N fire retardant systems is selected from char-forming agent, catalyzer and whipping agent, wherein from char-forming agent: catalyzer: the weight ratio of whipping agent=10-20 part: 40-60 part: 30-40 part; Described char-forming agent is selected from tetramethylolmethane; Described catalyzer is selected from ammonium polyphosphate; Described whipping agent is selected from trimeric cyanamide and urea, and the ratio of trimeric cyanamide and urea is 8:2.
Fire retarding synergist is selected from one or more in pure aluminium silicate, zinc borate, aluminium hydroxide, magnesium hydroxide, expansible black lead, mica, red phosphorus, the aluminum oxide, if two or more, the ratio between them is 1:1.
Auxiliary agent is selected from one or more in water glass, methyl-silicone oil, titanate coupling agent, dibutyl phthalate, Soxylat A 25-7, OP-10, Sodium hexametaphosphate 99, the carboxymethyl cellulose.
Filler is selected from one or more in kaolin, wilkinite, titanium dioxide, ferric oxide, the silicon-dioxide, if two or more, the ratio between them is 1:1.
