Abstract
The invention relates to a production method of phenolic aldehyde foam, which adopts the following raw materials and steps: firstly, carboxyl nitrile rubber and linear soluble phenolic resin are mixed, and stirred for 4 hours at 60 DEG C; secondly, the temperature of the obtained mixed liquor is decreased to 25 DEG C, and A4 level curing accelerator TMTD is added and stirred for 30 minutes; thirdly, benzene sulfonic acid and phosphoric acid are mixed in sequence; fourthly, phenolic resin, silicone oil, normal pentane and the obtained mixture are mixed, and poured into a die box after being stirred; fifthly, the die box is positioned in a 68 to 70 DEG C environment for 10 minutes to get the finished product. The invention has the advantages that not only the mechanical property of the phenolic resin can be enhanced, but also the heat resistance of the phenolic resin is increased.
Description
Technical field
The present invention relates to a kind of improved production technique that improves the phenol formaldehyde foam of product flexility, belong to the macromolecular organic compound technical field.
Background technology
Current, efficient, fire-retardant, the light body of market in urgent need, heat-insulation and heat-preservation material safe, with low cost.Phenolic aldehyde (PF) foam has both several specific characters, one of above-mentioned just this ideal organic insulation material, thereby market outlook are very wide.Nontoxic, no drip melt thing when the outstanding feature of phenol formaldehyde foam is critical oxygen index height, burning, use temperature is up to 150 ℃.When it directly contacts flame, the contact part carbonization, flame can not get expansion.In case leave flame, flame is from horizontal blanking.Phenol formaldehyde foam has better heat-resisting performance and cold tolerance again, and the use temperature scope can be between-150～150 ℃.Phenol formaldehyde foam can be by concentrated nitric acid and the highly basic erosion except only, and the erosional competency of resisting other mineral acid, organic acid, ammoniacal liquor and salt is stronger.Organic solvent, as benzene, acetone, but make it softening, but can not dissolve, though the intensity of phenol formaldehyde foam is subjected to the influence of its unit weight very big, for example the intensity of low unit weight goods is on the low side and character is fragile.Come just seem especially important of the production method of optimizing phenol formaldehyde foam therefrom.
Summary of the invention
The technical problem to be solved in the present invention is that the defective at prior art exists proposes a kind of production method that improves the phenol formaldehyde foam of product flexility, so as to improving the operational path of phenol formaldehyde foam, the phenolic foam products that the output flexility is up to standard.
Technical solution of the present invention is that the producer genealogy of law of described phenol formaldehyde foam adopts following raw material and processing step to make phenolic foam products:
(1), get carboxy nitrile rubber and line style resol resin in regular turn by 2～5: 100 weight ratio is mixed, stirred 4 hours under 60 ℃ of temperature the mixed solution of carboxy nitrile rubber and line style resol resin;
(2), the mixed solution of step (1) gained carboxy nitrile rubber and line style resol resin is cooled to 25 ℃, add A by 0.2～0.6% of this mixed solution weight
4The level vulcanization accelerator TMTD stir leave standstill after 30 minutes 24 hours standby;
(3), get Phenylsulfonic acid and phosphoric acid in regular turn by 6～8: 2～4 weight ratio compatibilities mix;
(4), get step (2) gained resol, silicone oil, Skellysolve A and step (3) gained mixture in regular turn by 95～105: 2.5～5: 5～7: 18～21 weight ratio compatibilities mix, and pour the preset die case after stirring into;
Embodiment 2:
The die box of gained mixture places 68 ℃～70 ℃ environment of constant temperature to keep promptly getting in 10 minutes the phenol formaldehyde foam finished product.
The invention has the beneficial effects as follows that in the present invention, the paracril plasticizing phenol formaldehyde belongs to physics blending modification, but in various degree grafting or block copolymerization reaction are arranged in solidification process, the add-on of paracril generally is controlled at 2～5%.In the mixture of solubility and lacquer resins, add carboxylic paracril, because of the two keys of the methylol in the resol resin and the divinyl in the paracril, carboxyl react, make between resol and the paracril close-coupled by chemical bond, therefore, the mechanical property of resol can be improved, also its thermotolerance can be improved.
Embodiment:
Embodiment 1:
(1), get carboxy nitrile rubber 2g and mix with line style resol resin 100g, under 60 ℃ of temperature continuously stirring 4 hours the mixed solution of carboxy nitrile rubber and line style resol resin;
(2), the mixed solution of step (1) gained carboxy nitrile rubber and line style resol resin is cooled to 25 ℃, add the commercially available A that is equivalent to this mixed solution weight 0.2%
4The level vulcanization accelerator TMTD, continuously stirring leave standstill after 30 minutes 24 hours standby;
(3), getting Phenylsulfonic acid 6g mixes with phosphoric acid 2g;
(4), with step (3) gained mixture 18g and 95g resol, 2.5g silicone oil, 5g Skellysolve A through mix with evenly stir after pour the preset die case into;
(5), the die box that will fill step (4) gained mixture places 68～70 ℃ of environment of constant temperature, keeps promptly getting in 10 minutes the phenol formaldehyde foam finished product.
Gained phenol formaldehyde foam finished product is measured its compressive strength by GB/T 8813-1988, and the result is 648Kpa; By the measured thermal conductivity of GB/T 10294-1988 is 0.018W/ (mK); In addition, press GB/T8811-1988 and GB/T 5486.2-2001 size up stability and folding strength respectively, the result shows that the dimensional stability of made phenol formaldehyde foam finished product is 0.44%, and folding strength is 2.78MPa.
