Abstract
The invention belongs to technical field of adhesive, is a kind of wood adhesive, is made up of following weight parts raw material：Urea 15~25, formaldehyde 25~35, sodium sulphate 2~6, water 5~10, metaformaldehyde 5~10, borax 1~5, ammonium chloride 1~5；Product of the present invention stability in low tempertaure storage is good, is particularly suitable for preserving for a long time in cold district, its water-tolerant, is mainly used in bonding between timber, there is good bonding effect.
Description
Technical field
The invention belongs to technical field of adhesive, specifically a kind of wood adhesive.
Background technology
It is glued（Bonding, it is bonded, is cementing, gluing）Refer to homogeneity or the skill that heterogeneous body surface is linked together with adhesive
Art, there is the features such as stress distribution is continuous, in light weight, or sealing, most technological temperatures are low, be glued especially suitable for different materials
The connection of matter, different-thickness, ultra-thin specification and complex component, is glued that RECENT DEVELOPMENTS is most fast, and application industry is extremely wide, and to high-new section
Learning technological progress and people's daily life improvement has significant impact.Therefore, it is very heavy to study, develop and produce all kinds of adhesive
Will.
The content of the invention
Present invention aim to a kind of wood adhesive is provided for the strong binding between timber.
A kind of wood adhesive of the present invention, is made up of following weight parts raw material：
The formaldehyde 25~35 of urea 15~25
The water 5~10 of sodium sulphate 2~6
The borax 1~5 of metaformaldehyde 5~10
Ammonium chloride 1~5.
A kind of wood adhesive of the present invention, its optimization formula are made up of following weight parts raw material：
The formaldehyde 32 of urea 22
The water 8 of sodium sulphate 4
The borax 3 of metaformaldehyde 7
Ammonium chloride 4.
Product of the present invention stability in low tempertaure storage is good, is particularly suitable for preserving for a long time in cold district, its water-tolerant,
It is mainly used in bonding between timber, there is good bonding effect.
