My Rigidbody can stick/hold walls

When I jump into a wall, and hold the button in the direction of the wall, my rigid body character can hold/stick to the wall for a bit. Here is my code (And no switching to character controller is not an option)

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class Controller : MonoBehaviour { public float moveSpeed; public float jumpSpeed; public float hitDistance; public bool isGrounded; public float airTime;

 // Use this for initialization
 void Start ()
 {
 }
 
 // Update is called once per frame
 void FixedUpdate ()
 {
     transform.rotation = Quaternion.identity;

     transform.Translate (Input.GetAxis ("Horizontal") * moveSpeed * Time.deltaTime,0f, 0f);

     if (Input.GetAxis ("Horizontal") != 0) { 
         if (moveSpeed < 10) {
             
             moveSpeed += 0.1f;

         }

     }

     if (Input.GetAxis ("Horizontal") == 0) {

         if (moveSpeed > 5) {

             moveSpeed -= 1;

         }

     }
     if (Input.GetAxis ("Jump") == 1) {
         airTime += 1;
     }
     if (Input.GetAxis ("Jump") == 0) {
         if (airTime > 0) {
             airTime = 0;
         }
     }

     if (airTime < 60)
     {
         transform.Translate (0f, Input.GetAxis ("Jump") * jumpSpeed * Time.deltaTime, 0f);

     }


     
 
 }
     

}

if someone could fix this it would make my week!
