Abstract
The invention relates to an embedded polyethylene glycol foam board. The embedded polyethylene glycol foam board comprises the following components: urea-formaldehyde resin, sodium dodecyl sulfate, phosphoric acid, urea, polyethylene glycol and water at a weight part ratio of (600-700):(5-8):(8-10):(3-6):(150-180):(200-300). A preparation method of the embedded polyethylene glycol foam board is characterized in that firstly polyethylene glycol liquid foam with a reticular structure is formed by using the urea-formaldehyde resin and the polyethylene glycol as main raw materials, as the polyethylene glycol foam is dried and cured, when the polyethylene glycol foam is in a liquid foam state, and the urea-formaldehyde resin is added, so that the urea-formaldehyde resin is uniformly mixed and distributed in the polyethylene glycol foam so as to form a foam system with double reticular structures, meanwhile, firstly the urea-formaldehyde resin is cured so as to form a solid foam structure by using a phosphorous acid as a curing agent according to the characteristic that the urea-formaldehyde resin is rapidly cured and set when reacting with the acid, and then polyethylene glycol solid foam is formed by drying, and the double-network crossed system foam is formed. The embedded polyethylene glycol foam board has the advantages of high compressive strength, good flexibility and elasticity, high sealing rate of foam holes and good water repellency.
Description
Technical field
The present invention relates to a kind of embedded polyoxyethylene glycol cystose and preparation method thereof.
Background technology
Urea-formaldehyde foam is a kind of cheap, application prospect is organic polymer material widely, in the recent period at architectural exterior insulation, agricultural seedling, grass planting, the research in the field such as improvement, ground of desertifying has had important breakthrough and development, but the crisp brittleness having due to urea-formaldehyde foam, cause it to become easy to break and frangible problem after plate, limited its application and production.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of embedded polyoxyethylene glycol cystose, this foam has the feature of fast shaping by solidifying agent by urea-formaldehyde foam, the binary that first forms polyoxyethylene glycol and urea-formaldehyde foam is liquid foam, in the process of urea-formaldehyde foam sizing, polyoxyethylene glycol foam is fixed in the foam system of urea-formaldehyde foam, by the dry polyoxyethylene glycol foam that forms second system, when this foam has been inherited the high feature of the ultimate compression strength of urea-formaldehyde foam, also there is good snappiness and elasticity, avoided urea-formaldehyde foam because of crisp brittleness simultaneously, low and the easy to break and frangible problem that causes of fracture resistence force.
Another object of the present invention is to provide the preparation method of embedded polyoxyethylene glycol cystose.
The problem existing in order to solve prior art, the technical solution used in the present invention is:
Embedded polyoxyethylene glycol cystose, is made up of according to the following number of weight ratio following component:
Urea-formaldehyde resin: sodium lauryl sulphate: phosphoric acid: urea: polyoxyethylene glycol: water=600-700: 5-8: 8-10: 3-6: 150-180: 200-300.
Described embedded polyoxyethylene glycol cystose is made up of according to the following number of weight ratio following component:
Urea-formaldehyde resin: sodium lauryl sulphate: phosphoric acid: urea: polyoxyethylene glycol: water=680: 7: 9: 5: 165: 245.
Prepare embedded polyoxyethylene glycol cystose method, comprise the following steps:
(1), prepare the first system foam: get the sodium lauryl sulphate, urea and the water that meet above-mentioned parts by weight and be made into expanding foam solution, expanding foam solution is stirred and adds after foaming the polyoxyethylene glycol of described weight part fully to stir to form polyoxyethylene glycol liquid foam with agitator;
(2), prepare second system foam: in polyoxyethylene glycol liquid foam, add the urea-formaldehyde resin of described weight part to stir to make urea-formaldehyde resin evenly to embed and in polyoxyethylene glycol liquid foam, form two net intersection system foams;
(3), pour mould molding into after adding the phosphoric acid mixing and stirring of described weight part;
(4), curing and demolding seasoning.
Advantage and effect that the present invention has are:
The present invention is take urea-formaldehyde resin and polyoxyethylene glycol as main raw material, distinguish traditional way of making urea-formaldehyde resin properties-correcting agent of polyoxyethylene glycol, first form cancellated polyoxyethylene glycol liquid foam, because polyoxyethylene glycol foam is dry solidification, in the time of its liquid foam state, add urea-formaldehyde resin, make the even mixed distribution of urea-formaldehyde resin in polyoxyethylene glycol foam, form two cancellated foam systems, utilize urea-formaldehyde resin to meet the characteristic of sour fast setting sizing simultaneously, take phosphoric acid as solidifying agent, first solidify urea-formaldehyde resin formation of foam solid foam structure, then by the dry polyoxyethylene glycol solid foam that forms again, form two net intersection system foams.Embedded polyoxyethylene glycol cystose has possessed the high advantage of urea-formaldehyde foam ultimate compression strength, has possessed the snappiness of polyoxyethylene glycol foam, the feature of good springiness simultaneously, although be that binary is foam, foam hole enclosed is high, water repellency is good, can be used for architectural exterior insulation, the fields such as packing.
