Description
Technical field
The present invention relates to the preparation method of timber preservative dry powder.
Background technology
Phenolic resin is the general designation that phenols and aldehydes form resin under catalyst action.It is industrialization earliest (1910
Year, German Bakelite) synthesis high polymer material.In the time in a nearly century, it is used for many industrial fields, now
It is still important synthesis high polymer material.Phenolic resin is to use one of extensive main glue kind in wood processing field, its
Consumption is only second to Lauxite.Especially phenolic resin has special meaning in terms of water-fast, weatherability woodwork is produced.
Synvaren has that heat-resist, adhesive strength is high, ageing-resistant performance is good and electrical insulating property is excellent, and valency
The features such as Lian Yiyong, therefore obtained relatively broad application.
Phenolic resin adhesive polarity is big, bonding force is strong；Rigidity is big, heat resistance is high；Resistance to ag(e)ing is good；It is water-fast, oil resistant, resistance to
Chemical mediator, resistance to mould；Itself is easily modified, and also other adhesive can be modified.But phenolic resin adhesive color compared with
Deeply, there is certain fragility, be easily cracked, particularly water soluble phenol resin hardening time compared with Lauxite is longer, solidify temperature
Degree is high, strict to Veneer moisture requirement.Therefore urgently develop that a kind of new antiseptic property is good, fire resistance is good, good toughness,
The phenolic resin preservative dry powder not being easily cracked.
