Abstract
The present invention relates to a flame retarding and corrosion resisting agent for wood (bamboo) or plywood, which is prepared from zinc oxide, zinc bromide, zinc sulfate, zinc chloride, ammonium sulfate, ammonium hydrogen phosphate, sodium phosphate, boracic acid, borax, etc. The present invention can directly process wood (bamboo) products through flame retarding and corrosion resisting treatment, and the flame retarding and corrosion resisting performance of the present invention is not the surface effect of raw materials but the qualitative effect of the raw materials (full cells for short). Moreover, the processed wood does not deform, the water ratio, the bonding strength and other physical mechanics performance technical index values of the processed wood completely accord with the standards. The agent of the present invention has the advantages of low toxicity, little pollution, continuous closed cycle, no consumption waste, closed recovery of the waste of the agent and no environmental influence.
Description
The present invention relates to a kind of fire-retarding preservative, particularly a kind of wood (bamboo) material, glued board fire-retarding preservative.
To natural timber and bamboo wood, the mankind extensively utilize, and its more perfect processing is used, particularly timber with and the processing of the fire protection flame retarding antiseptic property of woodwork, modern times to timber and material products thereof are utilized, and make its energy safer, durable in the mankind, its meaning reality, far-reaching.
The treating of wood reagent of at present existing independent fire protecting performance, and treating of wood reagent with independent antiseptic property.But these reagent limitation are bigger, and its shortcoming is big to the corrosivity of production equipment, and are simultaneously owing to copper in the medicament has bigger contaminative to environment, therefore tighter to its discharging wastes standard control; In the medicament chromium compound is arranged in addition, its toxicity and the severe contamination that may cause environment are that World Environment Organization and National Environmental administrative department pay much attention to and strict control.
The objective of the invention is to avoid above-mentioned the deficiencies in the prior art part and a kind of quality requirement that timber and goods thereof can be reached fire retardant anticorrosion after processing is provided, and toxicity is low, pollute few wood (bamboo) material glued board fire-retarding preservative.
Purpose of the present invention can reach by following measure: the present invention is characterized in that choosing according to following main component and percentage by weight: zinc oxide (5～7%), zinc bromide (6～8%), zinc sulfate (3～5%), zinc chloride (6～8%), ammonium sulfate (14～16%), ammonium hydrogen phosphate (34～36%), sodium phosphate (17～19%), boric acid (4～6%), borax (2～4%).
Purpose of the present invention can also reach by following measure: each composition optimum weight percentage is: zinc oxide (6%), zinc bromide (7%), zinc sulfate (4%), zinc chloride (7%), ammonium sulfate (15%), ammonium hydrogen phosphate (35%), sodium phosphate (18%), boric acid (5%), borax (3%).
The present invention will now be further detailed embodiment:
Embodiment one
Choose zinc oxide (5%), zinc bromide (6%), zinc sulfate (3%), zinc chloride (6%), ammonium sulfate (16%), ammonium hydrogen phosphate (36%), sodium phosphate (19%), boric acid (6%), borax (3%).Above-mentioned substance is mixed, promptly becomes this fire-retarding preservative in proportion.
Embodiment two
Choose zinc oxide (7%), zinc bromide (8%), zinc sulfate (5%), zinc chloride (8%), ammonium sulfate (14%), ammonium hydrogen phosphate (34%), sodium phosphate (17%), boric acid (4%), borax (3%).Above-mentioned substance is stirred in proportion, mixes, promptly become this fire-retarding preservative.
Embodiment three
Choose zinc oxide (6%), zinc bromide (7%), zinc sulfate (4%), zinc chloride (7%), ammonium sulfate (15%), ammonium hydrogen phosphate (35%), sodium phosphate (18%), boric acid (5%), borax (3%).Above-mentioned substance is stirred, mixes, promptly becomes this fire-retarding preservative in proportion.
When utilizing this anticorrisive agent fire retardant to handle (wood) bamboo wood or glued board, its technological process is as follows: at first glued board (or timber) is carried out application of vacuum, again the antiseptic fire-retardation agent is sucked in the glued board by the mode that sucks, then glued board is carried out the adding pressure type pressure treatment, medicament is discharged in glued board, glued board is carried out application of vacuum again, preferably the air-dry finished product that promptly becomes of discharging.
The present invention has following advantage compared to existing technology:
1. but the natural timber raw material is processed former material and timber-work place Manage one time effect, the absolutely not former material of its fire protection flame retarding antiseptic property surface, But the effect of matter is called for short " full cell ".
2. can directly carry out fire retardant anticorrosion to timber-work and process, process Rear timber is indeformable, the material resources such as moisture content, bonding strength performance skill The art desired value also meets standard fully. In addition, do not affect in its use Upper seven, veneer.
3. medicament toxicity is low, pollution is few, and the continuous closed circulation of energy, and consumption is not wasted, and its discarded object also seals recovery, does not have the environment influence extremely.
Claims (2)
1. a wood (bamboo) material, glued board fire-retarding preservative is characterized in that choosing according to following main component and percentage by weight: zinc oxide 5～7%, zinc bromide 6～8%, zinc sulfate 3～5%, zinc chloride 6～8%, ammonium sulfate 14～16%, ammonium hydrogen phosphate 34～36%, sodium phosphate 17～19%, boric acid 4～6%, borax 2～4%.
2. fire-retarding preservative according to claim 1 is characterized in that: each composition percentage by weight is: zinc oxide 6%, zinc bromide 7%, zinc sulfate 4%, zinc chloride 7%, ammonium sulfate 15%, ammonium hydrogen phosphate 35%, sodium phosphate 18%, boric acid 5%, borax 3%.
