Description
Technical field:
Product of the present invention belongs to chemical building material field, and in particular to a kind of synvaren and preparation method thereof.
Background technique:
Phenolic resin be phenol and formaldehyde under catalysts conditions polycondensation, neutralized, washing and made of resin, select different
Catalyst, two resinoid of thermosetting property and thermoplasticity can be made, phenolic resin has good weak acid resistant and weak base performance, mechanics
Performance and heat resistance are widely used in the industries such as anticorrosion engineering, adhesive, fire proofing, grinding wheel manufacture.Phenolic resin
One important purposes is exactly to prepare binder, and single phenolic resin colloidality is crisp, and unmodified synvaren is mainly used
In bonding timber, foamed plastics and other porous materials, it can also be used to manufacture the bonding of glued board and essence casting sand mold.Phenolic aldehyde tree
Because producing containing formaldehyde and will receive certain limitation in, the novel environment friendly formaldehyde of low pollution is produced rouge, into
And the new phenolic resin of environment-friendly type without formaldehyde is produced, new phenolic resin has excellent mechanical performances, heat resistance, cohesive force
By force, chemical stability is good, heat resistance is high, hardening when shrink the advantages that small, adhesion strength is high, it the shortcomings that be that price is slightly higher, can
Selection uses as needed.In order to which the using effect of synvaren is more preferable, in adhesive be added appropriate amount of auxiliary materials and
Reinforcing agent, adhesive obtained can be used for timber, laminated material, brake block, grinding wheel, lamp holder, hardboard and consolidate
Bulk resistor etc..
Summary of the invention:
Present invention mainly solves the problem of be to provide a kind of synvaren and preparation method thereof, produce what the product used
Raw material includes: Environmental protection phenol formaldehyde resin 20-22%, styrene 50-52%, furfuryl alcohol 10%, hexamethylenetetramine 11%, ammonia by weight ratio
Water 3%, sodium hydrate aqueous solution 4%.
The technical solution adopted by the present invention is that:
(1) styrene of formula ratio is sent into chemical reaction kettle, is warming up to 40-42 DEG C, start blender stirring, then slowly
Environmental protection phenol formaldehyde resin, the furfuryl alcohol, hexamethylenetetramine of formula ratio is added, is stirred 1.0-1.2 hours after mixing.
(2) it is cooled to room temperature, continues to stir, the ammonium hydroxide of formula ratio, sodium hydrate aqueous solution are sent into chemistry while stirring
Reaction kettle obtains finished product after being stirred to react 0.3-0.4 hours.
Preferably, the purity of the Environmental protection phenol formaldehyde resin is 65%.
Preferably, the purity of the styrene is 80%.
The beneficial effects of the present invention are: product is a kind of universal adhesive, it is using Environmental protection phenol formaldehyde resin as primary raw material
Obtained, product shrinks small and good insulating properties, weatherability, water-fast when having good mechanical property, heat resistance, hardening
Property, resistance to ag(e)ing, film forming and shock resistance, be mainly used for timber, laminated material, brake block, grinding wheel, lamp holder,
The bonding of hardboard and solid resistance.
