Abstract
The invention discloses a paraffin emulsion waterproof agent and a preparation method thereof, and relates to the technical field of the chemical industry. The paraffin emulsion waterproof agent comprises the following substances in parts by mass: 100 parts of paraffin, 9.5-10.5 parts of stearic acid, 45-47 parts of 25% ammonia aqueous solution, and 180-190 parts of water. The paraffin emulsion waterproof agent and the preparation method can solve the problems that a paraffin emulsion has a pungent smell, emulsifying paraffin can easily cause layered demulsification, and the storage stability is poorer.
Description
Technical field
The present invention relates to chemical technology field, especially a kind of paraffin wax emulsions water-resisting agent for the production of wood-based plate and preparation method thereof.
Background technology
Wood-based plate comprises three kinds of fiberboard and shaving board, glued boards, these three kinds of sheet materials all are the products of wood industry timber comprehensive utilization, its composition also need have the sizing material of certain proportioning except xylon or wood shavings, veneer, make xylon or wood shavings, veneer through the hot-pressing processing glue molding.In the production process of fiberboard and shaving board, in order to strengthen the water resistance of sheet material, the method that extensively adopts in the production is to apply water-proof material to fiber or wood shavings, using maximum water-proof materials at present is solid paraffin and paraffin wax emulsions, because need in advance fusing when solid paraffin uses, consume mass energy; And in use easily cause line clogging.Therefore paraffin wax emulsions more and more replaces solid paraffin in the whole world.And the quality of paraffin wax emulsions quality directly affects the water resistance of product; Existing a kind of paraffin wax emulsions water-resisting agent commonly used is by paraffin, oleic acid, and ammoniacal liquor, emulsified water and dilution water consist of; This paraffin wax emulsions water-resisting agent and preparation method thereof has irritating smell because of oleic acid wherein, and is larger on the operating environment impact aborning; The other easy layering breakdown of emulsion of this paraffin wax emulsions water-resisting agent emulsifying wax, stability in storage is relatively poor.
Summary of the invention
Technical problem to be solved by this invention provides a kind of paraffin wax emulsions water-resisting agent and preparation method thereof, and it can solve paraffin wax emulsions irritating smell and the easy layering breakdown of emulsion of emulsifying wax, the problem that stability in storage is relatively poor.
In order to address the above problem, technical scheme of the present invention is: this paraffin wax emulsions water-resisting agent is comprised of the material of following mass parts:
Paraffin: 100
Stearic acid: 9.5-10.5
25% ammonia soln: 45-47
Water: 180-190.
In the technique scheme, more specifically scheme can also be:
Described paraffin wax emulsions water-resisting agent is comprised of the material of following mass parts:
Paraffin: 100
Stearic acid: 9.5
25% ammonia soln: 47
Water: 180.
Described paraffin wax emulsions water-resisting agent is comprised of the material of following mass parts:
Paraffin: 100
Stearic acid: 10.5
25% ammonia soln: 45
Water: 190.
This paraffin wax emulsions water-resisting agent adopts the material of following mass parts to form:
Paraffin: 100
Stearic acid: 9.5-10.5
25% ammonia soln: 45-47
Water: 180-190;
Making step is:
(1) adds successively the water, paraffin, stearic acid of formula ratio to Emulsion cask;
(2) will add mixture heating up in the Emulsion cask to 90-93 ℃, and after paraffin and stearic acid melt fully, remove solid sundries with the string bag, and with 50-60 rev/min stirring velocity mixture is stirred; Temperature remains on 89-93 ℃, stirs 30 minutes;
(3) with 900-1200 rev/min stirring velocity mixture is stirred and slowly add 25% ammonia soln, the speed that adds ammonia soln is advisable not produce a large amount of foams, adds ammonia soln and must be controlled in 5 minutes, and temperature is 86-91 ℃ of scope;
(4) add ammonia soln after, with 50-60 rev/min stirring velocity mixture is stirred again, simultaneously mixture is cooled off;
Stop cooling when (5) being cooled to below 45 ℃, stop simultaneously stirring, namely obtain this paraffin wax emulsions water-resisting agent.
Because adopt technique scheme, the present invention has following beneficial effect:
1, the stearic acid that adopts of the present invention does not have the irritating smell of oleic acid, can improve operating environment;
2, be difficult for breakdown of emulsion after the emulsification of the present invention, stability is high, can stably stored six months, be easy to the board materials production allotment;
3, water resistance of the present invention is good, and operating procedure is easy, uses manpower and material resources sparingly.
