Abstract
The invention provides an emulsion paraffin water repellent for a medium density fiber board, which is prepared by taking solid paraffin and water as main materials, lauryl sodium sulfate, SPAN-60 and monoglyceride as emulsifiers, peregal 0 and tween-80 as catalysts and polyvinylalcohol as a colloid protecting agent. The water repellent comprises the following components in portion by weight: 40 to 45 portions of paraffin, 45 to 50 portions of water, 1.0 to 1.5 portions of lauryl sodium sulfate, 1.5 to 2.5 portions of SPAN-60, 0.5 to 1.0 portion of monoglyceride, 0.5 to 1.0 portion of peregal 0, 1.0 to 1.5 portions of tween-80, and 0.1 to 0.5 portion of polyvinylalcohol. The water repellent is unnecessarily melted or dissolved by a solvent when used; in addition, the water repellent also has the advantages of even film forming, small granularity, good dispersibility, good storing stability, easy combination with water solutions or emulsions of other materials for use, safety, high efficiency, economy and convenience, and can meet the requirements of the water repellent on low paraffin consumption and good water resisting property in the fiber board industry.
Description
Technical field
The present invention relates to a kind of medium density fibre board (MDF) water-resisting agent, be specifically related to a kind of medium density fibre board (MDF) emulsion paraffin water repellent.
Background technology
Medium density fibre board (MDF) is the product of timber resources comprehensive utilization, is the main raw material(s) of furniture, is taking wood fibre or other plant fiber as raw material, applies a certain proportion of tackiness agent and water-resisting agent, under heating and pressurizing condition, and the sheet material being pressed into.Sheet material after moulding has higher mechanical strength and water resistance.Emulsified olefin and solid paraffin are fiberboard sector application water-resisting agents widely, in Fibreboard Production, the WATER REPELLENT procedure that is absolutely necessary, otherwise, because wood materials is mushy organism, after moisture absorption, water suction, sheet material expansion modification, strength decreased, affects its range of application and work-ing life.
Emulsion paraffin water repellent is the substitute of paraffin.It is taking paraffin as anti-water carrier, being equipped with the chemical combination such as emulsifying agent, catalyzer forms, product stability is good, in fiberboard manufacturing processed, by breakdown of emulsion effectively, can make small Wax particles separate out from water, be adsorbed on equably on xylon, thereby improve the quality of fiberboard, and reduced wax consumption.Therefore emulsified olefin is widely used in fiberboard industry as water-resisting agent.
Summary of the invention
The invention provides a kind of medium density fibre board (MDF) emulsion paraffin water repellent and preparation method thereof.
The technical solution used in the present invention is:
Taking solid paraffin, water, sodium lauryl sulphate, this dish-60, mono-glycerides, peregal 0, tween-80, polyvinyl alcohol as component raw material.
Taking solid paraffin and water as main raw material, with sodium lauryl sulphate, this dish-60, mono-glycerides be emulsifying agent, with peregal 0, tween-80 be catalyzer, be that colloid protective agent is prepared emulsion paraffin water repellent with polyvinyl alcohol.
The each composition weight proportioning of paraffin wax emulsions of the present invention is as follows: 40～45 parts, paraffin, 45～50 parts, water, 1.0～1.5 parts of sodium lauryl sulphate,-60 1.5～2.5 parts, this dish, 0.5～1.0 part of mono-glycerides, 0 0.5～1.0 parts of peregals, 1.0～1.5 parts of tween-80s, 0.1～0.5 part of polyvinyl alcohol.
Medium density fibre board (MDF) of the present invention by the concrete production method of emulsion paraffin water repellent is:
Step 1: add solid paraffin, water in the reactor of being furnished with stirring rake, sodium lauryl sulphate is heated to 60 DEG C～75 DEG C jointly, adds this dish-60, mono-glycerides after stirring, be incubated 10～20 minutes;
Step 2: add peregal 0, tween-80,70 DEG C～80 DEG C insulations 50～60 minutes, emulsion is retrogradation gradually, adds appropriate water while there is thick liquid again, continued heating;
Step 3: add water, 60～70 DEG C of insulations 15 minutes, then add polyvinyl alcohol;
Step 4: slowly add water, 65～70 DEG C of insulations 15 minutes;
Step 5: slowly add water, 60～65 DEG C of insulations 15 minutes;
Step 6: slowly add water, 65～80 DEG C of insulations 15 minutes;
Step 7: be cooled to below 45 DEG C discharging.
The advantage of water-resisting agent of the present invention is: when use without heating and melting or by dissolution with solvents, its film forming is even, granularity is little, good dispersity, excellent storage stability, be easy to the aqueous solution or milk sap compound use with other materials, there is safety, the efficient and economic advantage such as convenient, can meet the requirement that fiberboard industry is low to water-resisting agent consumption wax amount, water resisting property is good.
