Description
Technical field
The invention belongs to mattress processing and manufacturing technologies, and in particular, to adhesive is used in a kind of processing of palm mattress.
Background technique
Arenga engleri Beccari, palm are also known as palm, belong to shrub plant, Palmae.The dry brown piece draped over one's shoulders from level to level of palm, can be by palm
Brown piece with it is cut off one by one, is dried for making the palm coir products such as brown pad, coir rope, straw rain cape.Toughness after palm becomes a useful person
Splendid, its raw material as natural plants elastomer especially has a variety of excellent nature.
Mattress be in order to guarantee consumer secure good health and comfortably sleep and use it is a kind of between human body and bed it
Between article, mattress material is various, different materials production mattress different sleeper effects can be brought to people.Palm mattress due to
Raw material it is healthy, renewable, be increasingly becoming one of main mattress.
With advocating, natural cry is higher and higher, and environmental problem is increasingly paid attention to, prepared by staple fibre
Occur a series of problems in the process, for example energy consumption is excessively high, cause more serious pollution to environment, product cost compared with
It is expensive, not pro-skin etc..So that natural plant fibre occupies certain market again.Palm fiber mattress is palm mattress, by hand
Shredded coconut meat (coconut palm palm fibre) fiber that weaving can not use also can use binder and be bonded into brown pad.The primary raw material of palm fibre pad has Arenga engleri Beccari silk
And shredded coconut meat, Arenga engleri Beccari silk are palm-bark rain cape (brown piece) fibers of palm；Shredded coconut meat is the fiber in the pericarp of coconut.Since palm mattress forms
More difficult, natural glue viscosity is not enough to maintain the stabilization of mattress, and contains formaldehyde etc. in existing artificial synthesized adhesive
Harmfulness ingredient, is harmful to human health, it is therefore desirable to which a kind of viscosity is good, while the dedicated gluing harmless to environment and human body
Agent.

In aqueous polyurethane emulsion matrix；Functional filler realizes effective and uniform dispersion and functionalization in aqueous polyurethane emulsion
The large specific surface area, high intensity of filler itself (nano-titanium dioxide, carbon black), so that functionalization filler and water polyurethane base
Active force between body is enhanced, and stress transfer occurs in receiving exogenic processes, so functionalization filler can effectively improve
The mechanical property of adhesive；Meanwhile the nano carbon black in functionalization filler, in heated situation, thermal insulation capabilities can be transferred to
To the two-phase interface of organic (polyurethane) and inorganic (titanium dioxide), need the breaking of covalent bonds between aqueous polyurethane hard section more
More heats enhances thermal stability, so that adhesive is initial so being able to suppress the thermal decomposition of adhesive to a certain extent
Decomposition temperature improves；
Aqueous polyurethane emulsion is prepared by the following method:
60g polyadipate -1,4-butanediol esterdiol is weighed, is added in the three-necked flask for having stirring rod, thermometer,
Temperature is 100 DEG C, vacuum degree is dehydrated 1h under being 0.095MPa；26.6g isophorone diisocyanate is weighed again is added this three mouthfuls
In flask, 3h is reacted at 90 DEG C；Add dihydromethyl propionic acid 3.6g, 1,4-butanediol 2.1g, melamine 1.8g, acetone
12mL reacts 1h at 80 DEG C；Continue that stannous octoate 0.007g, dibutyl tin dilaurate 0.009g is added dropwise, and 12mL is added
Acetone reacts 4h at 70 DEG C, is cooled to 55 DEG C, weighs hydroxy-ethyl acrylate 0.92g and is added in three-necked flask, anti-at 65 DEG C
Answer 2h；50 DEG C are cooled to, product is put into Emulsion cask, 3.5mL triethylamine is added and neutralizes, at 900r/min plus water carries out cream
Change, ethylenediamine 1.2g is added later and carries out chain extension, reacts 25min；Finally taken off in the case where temperature is 60 DEG C, vacuum degree is 0.095MPa
Acetone is removed, aqueous polyurethane emulsion is obtained；
Aqueous polyurethane is modified as crosslinking agent using melamine, by cross-linking modified aqueous polyurethane energy
Enough improve original heat resistance, the defect of poor water resistance, and the appropriately crosslinked cyberspace structure that can form densification, improves
The adhesive strength of adhesive；Furthermore main material used in palm mattress is monkey grass, and monkey grass is fine as a kind of plant
The oxygen-containing groups such as hydroxyl, carbonyl are contained on dimension, surface, hydrogen bond action can occur with-the NHCOO- on aqueous polyurethane segment, make
Obtaining adhesive matrix can be stronger with the effect of monkey grass, increases the bonding force of adhesive and fiber, improves and maintains mattress
Stability；
The adhesive is made by the following method:
Emulsifier is distributed in deionized water in the case where speed is the stirring state of 600-800r/min and forms water phase, by water
Property polyaminoester emulsion be distributed in water phase, functionalization filler, formaldehyde catching agent and levelling agent is added, stirs 120-150min, adds
Enter defoaming agent, continues to stir 30-40min, palm mattress processing adhesive is obtained by filtration.
