Between 30s/mm.
The adhesive is ultrapas modified urea-formaldehyde resin adhesive, and the solid content of adhesive is 55%, adhesive
Free formaldehyde content be 0.05%, in adhesive containing 1% zeolite powder, the fineness of zeolite powder is 150 mesh.
The present embodiment optimizes panel, the material of third substrate and corresponding technological parameter, makes finished product floor after processing
TVOC burst size can reach 0.28mg/ (m2H), burst size of methanal 0.8mg/L, critical thermal radiation flux 10.6kW/m2,
20s internal flame cusp height is less than 150mm, static bending strength 43MPa, elasticity modulus 4180MPa, surface abrasion resistance 0.10g/100r, paint
Film hardness 3H；Further improve structural behaviour, flame retardant effect and the security performance of floor entirety.
Experimental example 1: respectively identical 5 parts of ground board raw material is processed to obtain floor sample by processing technology of the invention
Product, wherein plate sample A step 2. and 4. in replace flame-retarding adhesive to bond the adhesive, and save step 5.；Ground
Plate sample B step 1. in replace adhesive to bond first substrate the flame-retarding adhesive, and save step 5.；Floor sample
Product C step 2. and 4. in replace flame-retarding adhesive to bond the adhesive；Ground plate sample D presses processing work of the present invention
Skill is processed；Ground plate sample E step 1. in by flame-retarding adhesive replace adhesive first substrate is bonded；Then divide
It is other that physicochemical property test is carried out to 5 parts of ground plate samples.Experimental result is as shown in table 1:
Influence of 1 technique of table to finished product flame retardant property
It can intuitively be found out by table 1, the treatment process pair of fire retardant is added in panel surface coating fire retarding paint, adhesive
20s internal flame cusp height does not influence.And by the anti-flammability in GB 8624-2012 " construction material and classification of combustion properties of building materials and products "
Energy foundation, B1-C grades of requirements are not satisfied in option A, B and C.The test result of scheme D, E meets B1-C grades of requirements, but scheme E
Flame retardant effect is not obvious compared to scheme D；It will lead to the decline of substrate adhesive strength due to adding fire retardant in adhesive, and
Fire retardant can gradually volatilize formaldehyde and TVOC after adhesion, so that the health to user causes a hidden trouble.Therefore, used in the present invention
Panel surface coats fire retarding paint, and the mode of two layers of addition fire retardant, which enables floor simultaneously, on substrate has good fire-retardant effect
Fruit and security performance.

Product；A copy of it plate sample be not added with adsorbent material in processing, in adhesive, another ground plate sample in processing,
By the zeolite powder of 1% content of addition of the present invention in its adhesive.Experimental result is as shown in table 2:
Influence of 2 adsorbent of table to properties of product
| Burst size of methanal (mg/L) | TVOC(mg/m2·h) | |
| Without adsorbent material | 1.2 | 0.36 |
| 1% zeolite powder | 0.8 | 0.28 |
Can intuitively be found out by table 2, in adhesive the addition of zeolite powder can be effectively reduced floor burst size of methanal and
TVOC burst size, to improve security performance of the invention.
