Abstract
The invention discloses a novel hot-melt adhesive which comprises pentaerythritol rosin ester, hydrogenated rosin ester, paraffin and an ethylene-vinyl acetate copolymer, wherein the percentage by weight of the pentaerythritol rosin ester in the novel hot-melt adhesive is 32% to 36%, the percentage by weight of the hydrogenated rosin ester in the novel hot-melt adhesive is 4% to 8%, the percentage by weight of the paraffin in the novel hot-melt adhesive is 1% to 5%, and the percentage by weight of the ethylene-vinyl acetate copolymer in the novel hot-melt adhesive is 51% to 55%. Through the way, the novel hot-melt adhesive disclosed by the invention is prepared by mixing various raw materials, and the prepared adhesive works excellently in the aspect of anti-oxidation, is applicable to manufacturing of a synthetic wood board, has the advantage of improving the strength and durability of the wood board and is low in cost.
Description
Technical field
The present invention relates to Hotmelt Adhesive field, particularly relate to a kind of new-type heat-melting type tackiness agent.
Background technology
Hotmelt Adhesive is a kind of solid binder, makes to use after adhesive melts by heating, uses more in the processing of plank.By Hotmelt Adhesive, wood fragments bits or single plate are added to heat bonding, form well-set slab, saved wood raw material, and moulding is convenient, can make larger area veneer, cost is also relatively cheap.
Common Hotmelt Adhesive has been grown easily and be oxidized in air duration of service, aging speed is accelerated, easily there is cracking or metamorphism at panel or support junction in the furniture that therefore partial synthesis plank is made, do not have work-ing life long solid wood furniture time.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of new-type heat-melting type tackiness agent, and ageing-resistant performance is outstanding, and Thermoadhesive is good, the plank long service life of making.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of new-type heat-melting type tackiness agent is provided, comprise: rosin pentaerythritol ester, hydrogenated wood rosin glycerol ester, paraffin and ethylene-vinyl acetate copolymer, described rosin pentaerythritol ester accounts for 32% ~ 36% in new-type heat-melting type tackiness agent, described hydrogenated wood rosin glycerol ester accounts for 4% ~ 8% in new-type heat-melting type tackiness agent, described paraffin accounts for 1% ~ 5% in new-type heat-melting type tackiness agent, described ethylene-vinyl acetate copolymer accounts for 51% ~ 55% in new-type heat-melting type tackiness agent.
In a preferred embodiment of the present invention, described rosin pentaerythritol ester accounts for 32% ~ 36% in new-type heat-melting type tackiness agent.
In a preferred embodiment of the present invention, described hydrogenated wood rosin glycerol ester accounts for 4% ~ 8% in new-type heat-melting type tackiness agent.
In a preferred embodiment of the present invention, described paraffin accounts for 1% ~ 5% in new-type heat-melting type tackiness agent.
In a preferred embodiment of the present invention, described ethylene-vinyl acetate copolymer accounts for 51% ~ 55% in new-type heat-melting type tackiness agent.
The invention has the beneficial effects as follows: a kind of new-type heat-melting type tackiness agent that the present invention points out, employing plurality of raw materials is mixed, and the tackiness agent obtaining does well aspect anti-oxidant, is applicable to making Homogenholz, improve intensity and the wearing quality of plank, and with low cost.
Embodiment
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of new-type heat-melting type tackiness agent, comprise: rosin pentaerythritol ester, hydrogenated wood rosin glycerol ester, paraffin and ethylene-vinyl acetate copolymer, above-mentioned 4 Raws are fully merged, described rosin pentaerythritol ester accounts for 32% ~ 36% in new-type heat-melting type tackiness agent, described hydrogenated wood rosin glycerol ester accounts for 4% ~ 8% in new-type heat-melting type tackiness agent, described paraffin accounts for 1% ~ 5% in new-type heat-melting type tackiness agent, described ethylene-vinyl acetate copolymer accounts for 51% ~ 55% in new-type heat-melting type tackiness agent.
A kind of new-type heat-melting type of the present invention tackiness agent contains multiple stickiness composition, and described rosin pentaerythritol ester accounts for 32% ~ 36% in new-type heat-melting type tackiness agent.
Further, described hydrogenated wood rosin glycerol ester accounts for 4% ~ 8% in new-type heat-melting type tackiness agent.The antioxidant property of hydrogenated wood rosin glycerol ester is good, and fragility is little, and thermostability is high, and unlikely oxidation in air is not easy to change under the effect of light.
Further, described paraffin accounts for 1% ~ 5% in new-type heat-melting type tackiness agent.
Further, described ethylene-vinyl acetate copolymer accounts for 51% ~ 55% in new-type heat-melting type tackiness agent.
In sum, a kind of new-type heat-melting type tackiness agent that the present invention points out, compared with common plank tackiness agent, is ensureing, on the basis of bond properties, to have improved antioxidant property, and synthetic boarding is firm, and wearing quality is good.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
