Problems solved by technology

[0004] Some of the school desks in the prior art use flame-retardant boards, but the related materials contain more formaldehyde, which affects human health, and also has the following disadvantages:
[0005] 1. The flame retardant performance is not good enough, and the strength is not strong enough;
[0006] 2. The boards in the prior art do not have other functions, such as refreshing and water absorption, which will cause water stains to soak on the desk after the surface of the desk is wet.

Abstract

The invention provides a board with flame-retardant effect. The raw materials of the board include: Sophora japonica powder and pot bottom ash; the raw materials of the board also include kaolin. The present invention also provides a method for preparing a board with a flame-retardant effect, which is characterized in that: the method includes a step of compounding and strengthening; the step of compounding and strengthening: kaolin and ground sorghum straw, peanut shell powder, The camphor powder and flame retardant are sent to the high-speed mixer according to the number of raw materials for mixing; the mixing temperature is controlled at 62-68°C, the mixing time is 30-50min, and the speed is 500-800r / min until the material emits a strong camphor fragrance. The plate with excellent flame-retardant effect prepared by the invention has an oxygen index of 58-62%; a notched impact strength of 16-18 KJ / m2; a tensile strength of 42-45MPa; and an elongation at break of 28-30%.

Description

technical field [0001] The invention relates to a composite board and a preparation method thereof, in particular to a board with a flame-retardant effect and a preparation method thereof. Background technique [0002] The role of flame retardants in fire safety has been proven. According to the assessment of the European Commission, the use of flame retardants has reduced the number of fire deaths in Europe by 20% in the past 10 years. According to relevant reports from Global Plastification, in the two accidents of the Asiana Airlines flight crash in San Francisco in 2013 and the Air France flight crash in Toronto in 2005, because the flame retardants used meet the requirements of the American aviation industry for fire-resistant safety seats People survived because of the regulations required by chairs and cargo planes. [0003] In recent years, fires have occurred in many places, especially the fires caused by educational activities such as school experiments that caus...
