Description

Finishing uses formaldehydeless light composite board
Technical field
The present invention relates to technical field of polymer composite materials, and in particular to one kind finishing uses formaldehydeless light composite board.
Background technology
The indoor pollution of China is more serious, and at present on indoor dirt first, finishing material is the topmost pollution of formaldehyde One of source.The change of finishing material is one of product of modern society's high speed development.
The life of the not only let us of being showing improvement or progress day by day of science and technology is greatly improved, while also bringing in the past not Trouble and disaster.When finishing material is manufactured, many businessmans are substantial amounts of to use some chemical articles for interests, these Chemical article use a small amount of in prescribed limit will not produce very big problem, but if these changes of heavy dose of use Articles for use are learned, manufacture finishing material is become indoor pollution source, more seriously it can produce great threat to human body, Damage our health.Formaldehyde is exactly a kind of many finishing producers most long chemical raw material added in process of production.Therefore new Formaldehyde Pollution of Indoor Air is caused to be nowadays common problem after having fitted up in room.Statistics shows, about 68% human body Disease is relevant with indoor pollution, and harm of the indoor environmental pollution to human body is many-sided and multifarious.
Medical research shows that harmful chemical substance can cause upper respiratory tract irritation, and such as nasal cavity dryness is itched, blocked up Plug flow tears, sneeze, smell decline, throat burn feeling or foreign body sensation, or even cough celostomia.With local respiratory tract mucosal immunity Dysregulation and phagocytosis, the function reduction for removing the foreign matters such as virus, bacterium, it is easy to induce lower respiratory tract i.e. trachea-bronchial epithelial cell And the inflammatory reaction and infection of lung, involve whole respiratory system.The especially two or more chemical substance accumulations such as arene When, poisoning symptom can be caused, local mucous membrane is not only damaged, it is also possible to the Novel presentation of ear,nose ＆ throat occurs, and then influences whole body.
Biologic contamination, essentially from the acarid that parasitizes in carpet, sofa, bed clothes, clothing, down toy and other thin Bacterium；Flowers, birds, fish and insects and pathogenic microorganism, parasite in cat and dog pet that family raises etc..Come from room dirt, carpet, birds and beasts plumage Acarid, fungi in the bedding such as hair and pillow, bed clothes are medically referred to as anaphylactogen, can often trigger human allergy anti- Answer, most commonly allergic rhinitis and anaphylaxis dermatosis.
Only contain carbon hydrogen element in polypropylene, oxygen index (OI) is low (about 18), from energy self-sustaining combustion after fire, and caloric value is big, produces Molten drop easily makes fire spread, adds the occurrence probability, incident classification and disaster relief difficulty of fire.In above-mentioned application field, in recent years Come due to legal provisions and user requires, it is necessary to which fiber has higher anti-flammability.Since 2008, mandatory national standards GB 20286-2006《Public place fire-retardant product and the requirement of component combustibility and mark》Implementation implement, the combustion to pavement Burn performance and made clear and definite restriction, be not less than GB 8624-2006《Construction material and product burns grading performance》Defined Df1 Level, and production smoke toxicity grade is not less than t1 grades, more accelerates the development and application process of the fire-retardant pavement of building.
For polypropylene fibre, fire-retardant effective ways mainly add fire retardant in melt spinning process makes fiber have lasting resistance Combustion property, halogen/antimony system is current ripe effective fire retardant, mainly by with the freedom of gas phase fire retardant mechanism-suppression gas-phase combustion Base chain reaction reaches fire-retardant purpose, has a good flame retardant effect under low concentration, but because exist in combustion by Produce the environmental issue of a large amount of corrosive hydrogen halides and other poisonous halide and limited by international community.
Alternatively, research at present and using it is more be halogen-free expanded flame-retardant system, this method mainly with containing The compound for having phosphorus-carbon-to-nitrogen constitutes acid source, charcoal source, source of the gas, and the synergy in " three sources " is caused during burning in material surface formation Close porous foam layer of charcoal, can both prevent internal layer high polymer further degraded and combustible to the release on surface, can prevent again Transmission and isolation oxygen source of the thermal source to high polymer, mainly with condensed phase and interruption heat exchange fire retardant mechanism, prevent the climing of flame Prolong and propagate.
This invention address that a kind of formaldehydeless light composite board of brand-new finishing of exploitation, meets present people and environmental protection is pacified The demand of full light composite board.
The content of the invention
In view of the deficienciess of the prior art, being fitted up the technical problem to be solved in the present invention is to provide one kind with formaldehydeless light Matter composite plate.
To solve the above problems, the present invention is adopted the following technical scheme that：
One kind finishing (is also known as with formaldehydeless light composite board：Glass/Polypropylene fiber light composite board), by being combined Two parts of plate and facial ornament are constituted, and the composite plate is prepared by 20-40wt% glass fibres, 60-80wt% flame-retardant polypropylene fibres Form；
The flame-retardant polypropylene fibre is prepared from by the raw material of following weight parts：80-100 parts of polypropylene chips, 20-30 parts Fire retardant, 10-20 part compatilizer.
Preferably, the fire retardant by triphenyl phosphate, phosphate toluene diphenyl ester, three (xylyl) phosphates mixing and Into the triphenyl phosphate, phosphate toluene diphenyl ester, the mass ratio of three (xylyl) phosphates are (1-3)：(1-3)：(1- 3)。
Preferably, the compatilizer is mixed by PP-g-MAH, AS-g-MAH, POE-g-MAH, the PP-g-MAH, AS-g-MAH, POE-g-MAH mass ratio are (1-3)：(1-3)：(1-3).
Preferably, described glass fibre, length is 6-8cm；Described polypropylene fiber, length is 6-11cm.
Preferably, it is characterised in that the facial ornament is cotton, burlap or chemical fiber plus material.
Specifically, in the present invention：
Triphenyl phosphate, No. CAS：115-86-6.
Phosphate toluene diphenyl ester, No. CAS：26444-49-5.
Three (xylyl) phosphates, No. CAS：25155-23-1.
The formaldehydeless light composite board of present invention finishing, it is excellent that polypropylene fiber carries out flame retardant treatment imparting light composite board Fire resistance, it is to avoid the potential safety hazard during production and use；Sheet material be by composite fibre cross lapping, acupuncture into Felt is formed, and stock dispersion is uniform, and glass fibre and polypropylene fiber interfacial adhesion degree are improved, and sheet material is had excellent synthesis mechanics Performance；Product is easy to shaping, and processing technology is simple, it is possible to increase production efficiency, reduces production cost, will not produce the change such as formaldehyde Learn contact scar.
